TRANSDIGM GROUP INCORPORATED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

TWENTY-SIX WEEK PERIODS ENDED APRIL 2, 2011 AND APRIL 3, 2010

(UNAUDITED)

1. DESCRIPTION OF THE BUSINESS

Description of the Business – TransDigm Group Incorporated (“TD Group”), through its wholly-owned subsidiary, TransDigm Inc., is a leading global designer, producer and supplier of highly engineered aircraft components for use on nearly all commercial and military aircraft in service today. TransDigm Inc. (which includes the Adel Wiggins Group), along with TransDigm Inc.’s direct and indirect wholly-owned operating subsidiaries (collectively, with TD Group, the “Company” or “TransDigm”), offers a broad range of proprietary aerospace components. TD Group has no significant assets or operations other than its 100% ownership of TransDigm Inc. TD Group’s common stock is listed on The New York Stock Exchange, or the NYSE, under the trading symbol “TDG.”

Major product offerings, substantially all of which are ultimately provided to end-users in the aerospace industry, include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, aircraft audio systems, specialized cockpit displays, engineered latching and locking devices, specialized lavatory components, engineered connectors and elastomers, rods and locking devices, NiCad batteries/chargers, and lighting and control technology.

Separate Financial Statements – Separate financial statements of TransDigm Inc. are not presented because TransDigm Inc.’s 7 ³/4% senior subordinated notes are fully and unconditionally guaranteed on a senior subordinated basis by TD Group and all existing domestic subsidiaries of TransDigm Inc. and because TD Group has no significant operations or assets separate from its investment in TransDigm Inc.

2. UNAUDITED INTERIM FINANCIAL INFORMATION

The financial information included herein is unaudited; however, the information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s financial position and results of operations and cash flows for the interim periods presented. These financial statements and notes should be read in conjunction with the financial statements and related notes for the year ended September 30, 2010 included in TD Group’s Form 10-K dated November 15, 2010 and Form 10-K/A dated November 19, 2010. As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“GAAP”). The September 30, 2010 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the twenty-six week period ended April 2, 2011 are not necessarily indicative of the results to be expected for the full year.

3. ACQUISITIONS

McKechnie Aerospace Holdings, Inc. – On December 6, 2010, TransDigm Inc. completed the acquisition of McKechnie Aerospace Holdings Inc. (“McKechnie Aerospace”), for approximately $1.27 billion in cash, subject to adjustments based on the level of working capital as of the closing date of the acquisition. McKechnie Aerospace, through its subsidiaries, is a leading global designer, producer and supplier of aerospace components, assemblies and subsystems for commercial aircraft, regional/business jets, military fixed wing and rotorcraft. These products fit well with TransDigm’s overall business direction.

The Company financed the McKechnie Aerospace acquisition, repaid borrowings under the previous senior secured credit facility and redeemed outstanding 7 ³/4% Senior Subordinated Notes due 2014 through a combination of the offering of $1.60 billion of 7 ³/4% Senior Subordinated Notes due 2018 and new term loan borrowings of $1.55 billion. See Note 9 to the Condensed Consolidated Financial Statements.

The total purchase price was allocated to the underlying assets acquired and liabilities assumed based upon management’s estimated fair values at the date of acquisition. The condensed consolidated balance sheet at April 2, 2011 reflects the preliminary purchase price allocation for the business. The Company obtained a preliminary third-party valuation of certain tangible and intangible assets of McKechnie Aerospace; thus, the values attributed to the acquired assets in the consolidated financial statements are subject to adjustment. To the extent the purchase price exceeded the estimated fair value of the net identifiable tangible and intangible assets acquired, such excess was allocated to goodwill.

-5-

The following table summarizes the preliminary purchase price allocation of the estimated fair values of the assets acquired and liabilities assumed at the transaction date (in thousands).

Assets acquired:
Current assets, excluding cash acquired	$	137,398
Property, plant and equipment		49,827
Intangible assets		433,000
Goodwill		879,819
Total assets acquired	$	1,500,044
Liabilities assumed:
Current liabilities	$	44,927
Deferred tax liabilities		159,408
Other noncurrent liabilities		30,351
Total liabilities assumed	$	234,686
Net assets acquired	$	1,265,358

The Company expects that the approximately $879.8 million of goodwill recognized for the acquisition will not be deductible for tax purposes.

The results of operations of McKechnie Aerospace are included in the Company’s consolidated financial statements from the date of the transaction. The Company recorded net sales of $99.1 million from the date of acquisition through April 2, 2011. Had the McKechnie acquisition and related financing transactions occurred at the beginning of the twenty-six week period ended April 3, 2010, unaudited pro forma consolidated results for the twenty-six week periods ended April 2, 2011 and April 3, 2010 would have been as follows (in thousands, except per share data):

	Twenty-Six Week Periods Ended
	April 2, 2011		April 3, 2010
Net sales	$	619,777	$	536,986
Net income (loss) applicable to common stock	$	140,720	$	(35,508	)
Net income (loss) per share: basic and diluted	$	2.64	$	(0.67	)

The unaudited pro forma consolidated results are based on the Company’s historical financial statements and those of McKechnie Aerospace and do not necessarily indicate the results of operations that would have resulted had the acquisition actually been completed at the beginning of the applicable period presented. The pro forma financial information assumes that the companies were combined as of October 1, 2009. The pro forma results for the twenty-six week period ended April 3, 2010 reflect the business combination accounting effects from the acquisition including amortization charges from the acquired intangible assets, inventory purchase accounting adjustments charged to cost of sales as the inventory is sold, increase in interest expense associated with debt incurred to fund the acquisition, refinancing costs associated with the refinancing of the Company’s entire debt structure and acquisition-related transaction costs. The unaudited pro forma consolidated results do not give effect to the synergies of the acquisition and are not indicative of the results of operations in future periods.

-6-

Talley Actuation – On December 31, 2010, TransDigm Inc. completed the acquisition of the actuation business of Telair International Inc. (“Talley Actuation”), a wholly-owned subsidiary of Teleflex Incorporated, for approximately $94 million in cash, subject to adjustments based on the level of working capital as of the closing date of the acquisition. Talley Actuation manufactures proprietary, highly engineered electro-mechanical products and other components for commercial and military aircraft. These products fit well with TransDigm’s overall business direction. The Company expects that the approximately $65 million of goodwill recognized for the acquisition will be deductible for tax purposes.

Semco Instruments – On September 3, 2010, TransDigm Inc. completed the acquisition of Semco Instruments, Inc. (“Semco Instruments”) for approximately $73.6 million in cash, which includes a purchase price adjustment of $3.0 million paid in the first quarter of fiscal 2011. Semco Instruments manufactures proprietary, highly engineered components for major turbo-prop, turbo-fan, and turbo-shaft engines, which are primarily used on helicopters, business jets and selected regional airplanes. These products fit well with TransDigm’s overall business direction. The Company expects that the approximately $42.3 million of goodwill recognized for the acquisition will not be deductible for tax purposes.

Dukes Aerospace – On December 2, 2009, TransDigm Inc., through a newly formed, wholly owned subsidiary of TransDigm Inc., Dukes Aerospace Inc., acquired certain assets and liabilities from Dukes, Inc. and GST Industries, Inc. (collectively “Dukes Aerospace”) for approximately $95.7 million in cash, subject to adjustment based on the level of working capital as of the closing date of the acquisition. In addition, the agreement provides for potential earn-out payments up to a total of $60 million over four years based on the achievement of certain growth targets. Dukes Aerospace is a supplier of proprietary, highly engineered components primarily to the business jet, regional jet, and military aerospace markets, along with commercial and military helicopter markets. The products are comprised primarily of highly engineered valves and certain pumps, solenoids and related components. These products fit well with TransDigm’s overall business direction. The purchase price allocation includes a fair value liability of $8.0 million recorded for the potential earn-out payments. The Company expects that the approximately $64.0 million of goodwill recognized for the acquisition will be deductible for tax purposes.

The Company accounted for the acquisitions of McKechnie Aerospace, Talley Actuation, Semco Instruments and Dukes Aerospace (collectively, the “Acquisitions”) using the acquisition method and included the results of operations of the Acquisitions in its consolidated financial statements from the effective date of each acquisition. The Company obtained a preliminary third-party valuation of certain tangible and intangible assets of McKechnie Aerospace and Talley Actuation; thus, the values attributed to those acquired assets in the consolidated financial statements are subject to adjustment. Pro forma net sales and results of operations for the twenty-six week periods ended April 2, 2011 and April 3, 2010, respectively, for the acquisitions of Talley Actuation, Semco Instruments and Dukes Aerospace, had they occurred at October 1, 2009, are not significant and, accordingly, are not provided.

The Acquisitions strengthen and expand our position to design, produce and supply highly engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategies. The purchase price paid for each acquisition reflects the current earnings before interest, taxes, depreciation and amortization (EBITDA) and cash flows, as well as, the future EBITDA and cash flows expected to be generated by the business, which is driven in most cases by the recurring aftermarket consumption over the life of a particular aircraft, which is estimated to be approximately 30 years.

4. DISCONTINUED OPERATIONS

On March 9, 2011 the Company completed the divestiture of its fastener business for approximately $240.0 million in cash, subject to adjustments based on the level of working capital as of the closing date. This business, which was acquired as part of the McKechnie Aerospace acquisition, is made up of Valley-Todeco, Inc. and Linread Ltd. The business designs and manufactures fasteners, fastening systems and bearings for commercial, military and general aviation aircraft. The results of operations and gain on sale of the fastener business has been presented as discontinued operations in the condensed consolidated statements of income.

The following summarized operating results for the fastener business is reported as discontinued operations in the accompanying condensed consolidated statements of income for the thirteen and twenty-six week periods ended April 2, 2011 (in thousands).

	Thirteen Week Period Ended			Twenty-Six Week Period Ended

9. DEBT

Revolving Credit Facility and Term Loan – In December 2010, TD Group’s wholly owned subsidiary, TransDigm Inc., entered into a Senior Secured Credit Facility, which consisted of a $1.55 billion term loan facility and a $245 million revolving credit facility (collectively, the “Existing Senior Secured Credit Facility”). The proceeds of the term loan were used to pay the purchase price of and related transaction expenses associated with the acquisition of McKechnie Aerospace and repay a portion of the amounts outstanding under the previous senior secured credit facility.

On February 14, 2011, TransDigm Inc. entered into a new Senior Secured Credit Facility which provides for $1.55 billion term loan facility (the “New Senior Secured Credit Facility”), which was fully drawn on February 14, 2011. The New Senior Secured Credit Facility replaced the term loan under the Existing Senior Secured Credit Facility and modified certain terms of the original agreement including extending the maturity date of the term loan and modifying the interest rate provisions.

On March 25, 2011, TransDigm entered into Amendment No. 1 (the “Amendment”) to the Existing Senior Secured Credit Facility. The Amendment provides for a modification to certain terms of the permitted indebtedness covenant contained in the Existing Senior Secured Credit Facility to modify the requirements for incurring certain additional senior indebtedness.

Under the terms of the New Senior Secured Credit Facility, TransDigm is entitled on one or more occasions, subject to the satisfaction of certain conditions, to request additional term loans under the New Senior Secured Credit Facility in the aggregate principal amount of up to $500 million (less any increase in the commitments under the revolving credit facility and/or additional term loans under the term loan facility under the Existing Senior Secured Credit Facility) to the extent that existing or new lenders agree to provide such additional term loans.

At April 2, 2011, the Company had $7.0 million letters of credit outstanding and $238.0 million of borrowings available under the Existing Senior Secured Credit Facility, as amended.

Under the New Senior Secured Credit Facility, the term loan matures in February 2017. Under the Existing Senior Secured Credit Facility, the revolving credit facility matures in December 2015. The term loan under the New Senior Secured Credit Facility requires quarterly principal payments that began on March 31, 2011.

The interest rates per annum applicable to the term loans under the New Senior Secured Credit Facility will be, at TransDigm’s option, equal to either an alternate base rate or an adjusted LIBO rate for one, two, three or six-month (or to the extent agreed to by each relevant lender, nine or twelve-month) interest periods chosen by TransDigm, in each case plus an applicable margin percentage. At April 2, 2011, the applicable interest rate on the term loan was 4.0%.

-10-

Under the terms of the New Senior Secured Credit Facility, the Company is required to pay the administrative agent certain fees. In addition, on the last day of each calendar quarter the Company is required to pay a commitment fee equal to the applicable rate per annum in effect from time to time of any unused commitments under the revolving credit line and certain other fees in respect of letters of credit that may be outstanding thereunder from time to time.

All of the indebtedness outstanding under the New Senior Secured Credit Facility is guaranteed by TD Group and all of TransDigm’s current and future domestic restricted subsidiaries (other than immaterial subsidiaries), and is secured by a first priority security interest in substantially all of the existing and future property and assets, including inventory, equipment, general intangibles, intellectual property, investment property and other personal property (but excluding leasehold interests and certain other assets) of TransDigm and all of TransDigm’s existing and future domestic restricted subsidiaries (other than immaterial subsidiaries), and a first priority pledge of the capital stock of TransDigm and its domestic subsidiaries and 65% of the voting capital stock of certain of TransDigm’s foreign subsidiaries.

The New Senior Secured Credit Facility contains certain covenants that limit the ability of TD Group, TransDigm and TransDigm’s restricted subsidiaries to, among other things, incur or guarantee additional indebtedness or issue preferred stock, pay distributions on, redeem or repurchase capital stock or redeem or repurchase subordinated debt, make investments, sell assets, enter into agreements that restrict distributions or other payments from restricted subsidiaries to TransDigm, incur or suffer to exist liens securing indebtedness, consolidate, merge or transfer all or substantially all of their assets, and engage in transactions with affiliates. At April 2, 2011, TransDigm was in compliance with all of the covenants contained in the New Senior Secured Credit Facility.

The term loan under the New Senior Secured Credit Facility requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as therein defined), commencing 90 days after the end of each fiscal year, commencing with the fiscal year ending September 30, 2012, subject to certain exceptions. In addition, subject to certain exceptions (including, with respect to asset sales, the reinvestment in productive assets), TransDigm will be required to prepay the loans outstanding under the term loan facility at 100% of the principal amount thereof, plus accrued and unpaid interest, with the net cash proceeds of certain asset sales and issuance or incurrence of certain indebtedness. In addition, if, prior to February 14, 2012, the principal amount of the term loans are (i) prepaid substantially concurrently with the incurrence by TD Group, TransDigm or any its subsidiaries of new bank loans that have an effective yield lower than the yield in effect on the term loans so prepaid or (ii) received by a lender due to a mandatory assignment following the failure of such lender to consent to an amendment of the New Senior Secured Credit Facility that has the effect of reducing the effective interest rate with respect to the term loans, such prepayment or receipt shall be accompanied by a premium of 1.0%.

Senior Subordinated Notes – In December 2010, TransDigm issued $1.6 billion in aggregate principal amount of its 7 ³/4% Senior Subordinated Notes due 2018 (the “2018 Notes”) at an issue price of 100% of the principal amount. The 2018 Notes represent unsecured obligations of TransDigm Inc. ranking subordinate to TransDigm Inc.’s senior debt, as defined in the indenture governing the 2018 Notes. Interest under the 2018 Notes is payable semi-annually.

The 2018 Notes are redeemable by TransDigm, in whole or in part, at specified redemption prices, which decline from 103.875% to 100% over the remaining term of the 2018 Notes, plus accrued and unpaid interest. Prior to December 15, 2013, TransDigm is permitted to redeem specified percentages of the 2018 Notes from the proceeds of equity offerings at a redemption price of 107.75%, plus accrued and unpaid interest. If a change in control of the Company occurs, the holders of the 2018 Notes will have the right to demand that TransDigm redeem the 2018 Notes at a purchase price equal to 101% of the principal amount of the 2018 Notes plus accrued and unpaid interest. The 2018 Notes contain many of the same restrictive covenants included in the New Senior Secured Credit Facility. TransDigm is in compliance with all of the covenants contained in the 2018 Notes.

TransDigm utilized a portion of the proceeds from the 2018 Notes to purchase approximately $968.6 million aggregate principal amount of its 7 ³/4% Senior Subordinated Notes due 2014 (the “2014 Notes”) representing all such 2014 Notes that were validly tendered at or prior to the consent expiration deadline pursuant to TransDigm’s previously announced cash offers to purchase any and all of its outstanding 2014 Notes in December 2010. TransDigm also received consents from holders of the required majority of the principal amount of the 2014 Notes to, among other modifications, eliminate substantially all of the restrictive covenants and certain events of default in the indentures governing the 2014 Notes.

-11-

Remaining proceeds from the 2018 Notes were utilized to pay off the remaining outstanding balance under the previous senior secured credit facility and for general corporate purposes.

During January 2011, TransDigm redeemed the remaining $31.4 million outstanding under the 2014 Notes.

The Company recorded refinancing costs of $1.6 million and $72.4, respectively, during the thirteen and twenty-six week periods ended April 2, 2011 representing charges resulting from the refinancing of TransDigm’s entire debt structure. The total charge for the twenty-six week period ended April 2, 2011 consisted of the premium of $42.4 million paid to redeem the 2014 Notes, the write-off of debt issue costs and unamortized note premium and discount of $25.7 million, and the settlement of the interest rate swap agreement and other expenses of $4.3 million.

At April 2, 2011 and September 30, 2010, the Company had the following debt outstanding (in thousands):

	April 2, 2011			September 30, 2010
Term Loans	$	1,546,125		$	780,000
Senior Subordinated Notes due 2018		1,600,000			—
Senior Subordinated Notes due 2014		—			991,646

Less current portion		(15,500	)		—
Long-term debt	$	3,130,625		$	1,771,646

Special Cash Dividend Payment – In October 2009, TransDigm made a special cash dividend to its stockholders of $7.65 per share and cash dividend equivalents payments (“Dividend Equivalent Payments”) to holders of options to purchase its common stock from the net proceeds of the $425 million Senior Subordinated Notes due 2014 issued in October 2009. After the payment of debt issue fees and expenses, the net proceeds amounted to approximately $404.5 million. The special cash dividend and Dividend Equivalent Payments of $404.9 million were paid in the first quarter of fiscal 2010 and $2.8 million were paid in the first quarter of fiscal 2011. The $425 million of 2014 Notes were included in the tender offer made in conjunction with the 2018 Notes issuance.

10. ENVIRONMENTAL LIABILITIES

Our operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations that govern, among other things, discharges of pollutants into the air and water, the generation, handling, storage and disposal of hazardous materials and wastes, the remediation of contamination and the health and safety of our employees. Environmental laws and regulations may require that the Company investigate and remediate the effects of the release or disposal of materials at sites associated with past and present operations. At certain facilities acquired in connection with the acquisition of McKechnie Aerospace or third-party sites utilized by subsidiaries of McKechnie Aerospace, subsidiaries of the Company have been identified as potentially responsible parties under the federal Superfund laws and comparable state laws. The Company is currently involved in the investigation and remediation of a number of sites under applicable laws.

Estimates of the Company’s environmental liabilities are based on current facts, laws, regulations and technology. These estimates take into consideration the Company’s prior experience and professional judgment of the Company’s environmental specialists. Estimates of the Company’s environmental liabilities are further subject to uncertainties regarding the nature and extent of site contamination, the range of remediation alternatives available, evolving remediation standards, imprecise engineering evaluations and cost estimates, the extent of corrective actions that may be required and the number and financial condition of other potentially responsible parties, as well as the extent of their responsibility for the remediation.

Accordingly, as investigation and remediation proceed, it is likely that adjustments in the Company’s accruals will be necessary to reflect new information. The amounts of any such adjustments could have a material adverse effect on the Company’s results of operations or cash flows in a given period. Based on currently available information, however, the Company does not believe that future environmental costs in excess of those accrued with respect to sites for which the Company has been identified as a potentially responsible party are likely to have a material adverse effect on the Company’s financial condition.

-12-

Environmental liabilities are recorded when the liability is probable and the costs are reasonably estimable, which generally is not later than at completion of a feasibility study or when the Company has recommended a remedy or has committed to an appropriate plan of action. The liabilities are reviewed periodically and, as investigation and remediation proceed, adjustments are made as necessary. Liabilities for losses from environmental remediation obligations do not consider the effects of inflation and anticipated expenditures are not discounted to their present value. The liabilities are not reduced by possible recoveries from insurance carriers or other third parties, but do reflect anticipated allocations among potentially responsible parties at federal Superfund sites or similar state-managed sites, third party indemnity obligations, and an assessment of the likelihood that such parties will fulfill their obligations at such sites.

The Company’s consolidated balance sheet includes the following for environmental remediation obligations (in thousands):

	April 2, 2011
Accrued liabilities	$	1,600
Other non-current liabilities		18,688
Total	$	20,288

11. INCOME TAXES

At the end of each reporting period, TD Group makes an estimate of its annual effective income tax rate. The estimate used in the year-to-date period may change in subsequent periods. During the thirteen week periods ended April 2, 2011 and April 3, 2010, the effective income tax rate was 36.1% and 36.2%, respectively. During the twenty-six week periods ended April 2, 2011 and April 3, 2010, the effective income tax rate was 36.5% and 36.0%, respectively.

TD Group and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions as well as foreign jurisdictions located in the United Kingdom, Belgium and Malaysia. The Company is no longer subject to U.S. federal examination for years before fiscal year 2009. In addition, the Company is subject to state and local income tax examinations for fiscal years 2006 through 2010.

At April 2, 2011 and September 30, 2010, TD Group had $6.7 million and $1.8 million in unrecognized tax benefits, the recognition of which would have an effect of approximately $6.1 million and $1.3 million on the effective tax rate at April 2, 2011 and September 30, 2010, respectively. The Company does not believe that the tax positions that comprise the unrecognized tax benefit amount will change significantly over the next 12 months. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense.

12. FAIR VALUE MEASUREMENTS

The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

-13-

The following summarizes the carrying amounts and fair values of financial instruments (in thousands):

			April 2, 2011				September 30, 2010
	Level		Carrying Amount		Fair Value		Carrying Amount		Fair Value

(1) Included in Accrued liabilities on the Condensed Consolidated Balance Sheet at September 30, 2010.

Interest rate swaps were measured at fair value using quoted market prices for the swap interest rate indexes over the term of the swap discounted to present value versus the fixed rate of the contract. The estimated fair value of the Company’s term loans was based on information provided by the agent under the Company’s senior secured credit facility. The estimated fair values of the Company’s 7 ³/4% senior subordinated notes due 2014 and 7 ³/4% senior subordinated notes due 2018 were based upon quoted market prices.

At September 30, 2010, an agreement was in place to swap variable interest rates on our previous senior secured credit facility for a fixed interest rate for the notional amount of $300 million through March 23, 2011. This interest rate swap agreement effectively converted the variable rate interest on the notional amount of our senior secured credit facility to a fixed rate of 3.04% plus the 2% margin percentage, over the term of the agreement. The interest rate swap agreement was terminated in December 2010 in conjunction with the repayment of the outstanding term loan balance under the previous senior secured credit facility.

13. COMPREHENSIVE INCOME

Comprehensive income, which primarily includes adjustments for changes in the fair values of the interest rate swap agreements on a net of tax basis and foreign currency translation adjustments, was approximately $51.3 million and $69.8 million for the twenty six week periods ended April 2, 2011 and April 3, 2010, respectively.

14. SUBSEQUENT EVENTS

On April 7, 2011 the Company completed the divestiture of Aero Quality Sales (“AQS”) for approximately $30 million in cash, subject to adjustments based on the level of working capital as of the closing date. AQS, which was acquired as part of the McKechnie Aerospace acquisition, is a distributor and service center of aircraft batteries and battery support equipment.

We have evaluated events subsequent to April 2, 2011, through the date the financial statements were issued, and determined that no events have occurred that require adjustment of or disclosure in the consolidated financial statements, other than as disclosed above.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of the Company’s financial condition and results of operations should be read together with TD Group’s consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q. References in this section to “TransDigm,” “the Company,” “we,” “us,” “our,” and similar references refer to TD Group, TransDigm Inc. and TransDigm Inc.’s subsidiaries, unless the context otherwise indicates. The following discussion may contain predictions, estimates and other forward-looking statements that involve a number of risks and uncertainties, including those discussed in this report. These risks could cause our actual results to differ materially from any future performance suggested below.

This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including, in particular, the statements about the Company’s plans, strategies and prospects under this section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Although the Company believes that its plans, intentions and expectations reflected in or suggested by such forward-looking statements are reasonable, the Company can give no assurance that such plans, intentions or expectations will be achieved. Many of the factors affecting these forward-looking statements are outside the control of the Company. Consequently, such forward-looking statements should be regarded solely as the Company’s current plans, estimates and beliefs. The Company does not undertake, and specifically declines, any obligation to publicly release the results of any revisions to these forward-looking statements that may be made to reflect any future events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events, except as required by applicable law. All forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by the foregoing cautionary statements.

Important factors that could cause actual results to differ materially from the forward-looking statements made in this Quarterly Report on Form 10-Q include but are not limited to: the sensitivity of our business to the number of flight hours that our customers’ planes spend aloft and our customers’ profitability, both of which are affected by general economic conditions; future terrorist attacks; our reliance on certain customers; the U.S. defense budget and risks associated with being a government supplier; failure to maintain government or industry approvals; failure to complete or successfully integrate acquisitions; our substantial indebtedness; potential environmental liabilities; and other factors. Please refer to the other information included in this Quarterly Report on Form 10-Q and to the Annual Report on Form 10-K and Form 10-K/A for additional information regarding the foregoing factors that may affect our business.

Overview

We believe we are a leading global designer, producer and supplier of highly engineered aircraft components for use on nearly all commercial and military aircraft in service today. Our business is well diversified due to the broad range of products we offer to our customers. Some of our more significant product offerings, substantially all of which are ultimately provided to end-users in the aerospace industry, include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, aircraft audio systems, specialized cockpit displays, engineered latching and locking devices, specialized lavatory components, engineered connectors and elastomers, rods and locking devices, NiCad batteries/chargers, and lighting and control technology. Each of these product offerings is composed of many individual products that are typically customized to meet the needs of a particular aircraft platform or customer.

For the second quarter of fiscal 2011, we generated net sales of $311.3 million and net income of $55.8 million. EBITDA As Defined was $146.7 million, or 47.1% of net sales. See below for certain information regarding EBITDA and EBITDA As Defined, including reconciliations of EBITDA and EBITDA As Defined to net income and net cash provided by operating activities.

This business, which was acquired as part of the McKechnie Aerospace acquisition, is made up of Valley-Todeco, Inc. and Linread Ltd. The business designs and manufactures fasteners, fastening systems and bearings for commercial, military and general aviation aircraft.

Non-GAAP Financial Measures

We present below certain financial information based on our EBITDA and EBITDA As Defined. References to “EBITDA” mean earnings before interest, taxes, depreciation and amortization, and references to “EBITDA As Defined” mean EBITDA plus, as applicable for each relevant period, certain adjustments as set forth in the reconciliations of net income to EBITDA and EBITDA As Defined and the reconciliations of net cash provided by operating activities to EBITDA and EBITDA As Defined presented below.

Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under accounting principles generally accepted in the United States of America (“GAAP”). We present EBITDA and EBITDA As Defined because we believe they are useful indicators for evaluating operating performance and liquidity.

Our management believes that EBITDA and EBITDA As Defined are useful as indicators of liquidity because securities analysts, investors, rating agencies and others use EBITDA to evaluate a company’s ability to incur and service debt. In addition, EBITDA As Defined is useful to investors because our revolving credit facility under our senior secured credit facility requires compliance, on a pro forma basis, with a financial covenant that measures the

-23-

ratio of the amount of our secured indebtedness to the amount of our Consolidated EBITDA defined in the same manner as we define EBITDA As Defined herein. This financial covenant is a material term of our senior secured credit facility as the failure to comply with such financial covenant could result in an event of default in respect of the revolving credit facility (and such an event of default could, in turn, result in an event of default under the indentures governing our 7 ³/4% senior subordinated notes).

In addition to the above, our management uses EBITDA As Defined to review and assess the performance of the management team in connection with employee incentive programs and to prepare its annual budget and financial projections. Moreover, our management uses EBITDA As Defined to evaluate acquisitions.

Although we use EBITDA and EBITDA As Defined as measures to assess the performance of our business and for the other purposes set forth above, the use of these non-GAAP financial measures as analytical tools has limitations, and you should not consider any of them in isolation, or as a substitute for analysis of our results of operations as reported in accordance with GAAP. Some of these limitations are:

• neither EBITDA nor EBITDA As Defined reflects the significant interest expense, or the cash requirements necessary to service interest payments, on our indebtedness;

• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and neither EBITDA nor EBITDA As Defined reflects any cash requirements for such replacements;

• the omission of the substantial amortization expense associated with our intangible assets further limits the usefulness of EBITDA and EBITDA As Defined;

• neither EBITDA nor EBITDA As Defined includes the payment of taxes, which is a necessary element of our operations; and

• EBITDA As Defined excludes the cash expense we have incurred to integrate acquired businesses into our operations, which is a necessary element of certain of our acquisitions.

Because of these limitations, EBITDA and EBITDA As Defined should not be considered as measures of discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by not viewing EBITDA or EBITDA As Defined in isolation and specifically by using other GAAP measures, such as net income, net sales and operating profit, to measure our operating performance. Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under GAAP, and neither should be considered as an alternative to net income or cash flow from operations determined in accordance with GAAP. Our calculation of EBITDA and EBITDA As Defined may not be comparable to the calculation of similarly titled measures reported by other companies.

Critical Accounting Policies

Our consolidated financial statements have been prepared in conformity with GAAP, which often requires the judgment of management in the selection and application of certain accounting principles and methods. Management believes that the quality and reasonableness of our most critical policies enable the fair presentation of our financial position and results of operations. However, investors are cautioned that the sensitivity of financial statements to these methods, assumptions and estimates could create materially different results under different conditions or using different assumptions.

We have identified the following as the most critical accounting policies upon which our financial status depends. These critical policies were determined by considering accounting policies that involve the most complex or subjective decisions or assessments. Our most critical accounting policies are as follows:

Revenue Recognition and Related Allowances: Revenue is recognized from the sale of products when title and risk of loss passes to the customer, which is generally at the time of shipment. Substantially all sales are made pursuant to firm, fixed-price purchase orders received from customers. Collectability of amounts recorded as revenue is reasonably assured at the time of sale. Provisions for returns, uncollectible accounts and the cost of repairs under contract warranty provisions are provided for in the same period as the related revenues are recorded and are principally based on historical results modified, as appropriate, by the most current information available. We have a history of making reasonably dependable estimates of such allowances; however, due to uncertainties inherent in the estimation process, it is possible that actual results may vary from the estimates and the differences could be material.

Management estimates the allowance for doubtful accounts based on the aging of the accounts receivable and customer creditworthiness. The allowance also incorporates a provision for the estimated impact of disputes with customers. Management’s estimate of the allowance amounts that are necessary includes amounts for specifically identified credit losses and a general amount for estimated credit losses based on historical information. The determination of the amount of the allowance for doubtful accounts is subject to significant levels of judgment and estimation by management. Depending on the resolution of potential credit and other collection issues, or if the financial condition of any of the Company’s customers were to deteriorate and their ability to make required payments were to become impaired, increases in these allowances may be required. Historically, changes in estimates in the allowance for doubtful accounts have not been significant.

The Company provides limited warranties in connection with the sale of its products. The warranty period for products sold varies throughout the Company’s operations, generally ranging from 90 days to six years. In addition, certain contracts with distributors contain right of return provisions. The Company accrues for estimated returns and warranty claims based on knowledge of product performance issues and based on excess inventories provided by its customers and industry sources. The Company also provides a general amount based on historical trends. To the extent total warranty claims differ from estimates, adjustments may be necessary. Historically, actual product returns and warranty claims have not differed materially from the estimates originally established.

Inventories: Inventories are stated at the lower of cost or market. Cost of inventories is determined by the average cost and the first-in, first-out (FIFO) methods for all locations except CEF, which determines the cost of inventories using the last-in, first-out (LIFO) method. Because the Company sells products that are installed on airframes that can be in-service for 30 or more years, it must keep a supply of such products on hand while the airframes are in use. Where management estimated that the current market value was below cost or determined that future demand was lower than current inventory levels, based on historical experience, current and projected market demand, current and projected volume trends and other relevant current and projected factors associated with the current economic conditions, a reduction in inventory cost to estimated net realizable value was made by recording a provision included in cost of sales. Although management believes that the Company’s estimates of excess and obsolete inventory are reasonable, actual results may differ materially from the estimates and additional provisions may be required in the future. In addition, in accordance with industry practice, all inventories are classified as current assets as all inventories are available and necessary to support current sales, even though a portion of the inventories may not be sold within one year. Historically, changes in estimates in the net realizable value of inventories have not been significant.

-27-

Intangible Assets: Mergers and acquisitions are accounted for using the acquisition method and have resulted in significant amounts of identifiable intangible assets and goodwill. Fair value adjustments to the Company’s assets and liabilities are recognized and the results of operations of the acquired business are included in our consolidated financial statements from the effective date of the merger or acquisition. We generally use third-party appraisals to assist us in determining the estimated fair value of the intangible assets.

Intangible assets other than goodwill are recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the intangible asset can be sold, transferred, licensed or exchanged, regardless of the Company’s intent to do so. Goodwill and identifiable intangible assets are recorded at their estimated fair value on the date of acquisition and are reviewed at least annually for impairment based on cash flow projections and fair value estimates.

GAAP requires that the annual, and any interim, impairment assessment be performed at the reporting unit level. The reporting unit level is the operating subsidiary level for the Company. Substantially all goodwill was determined and recognized for each operating subsidiary pursuant to the accounting for the merger or acquisition as of the date of each transaction, and therefore the allocation of goodwill among reporting units was immaterial for purposes of the impairment assessment. With respect to acquisitions integrated into an existing operating subsidiary, any related goodwill is combined with goodwill of the operating subsidiary.

At the time of goodwill impairment testing, management determines the estimated fair value through the use of a discounted cash flow valuation model incorporating discount rates commensurate with the risks involved for each reporting unit. If the calculated estimated fair value is less than the current carrying value, impairment of goodwill of the reporting unit may exist. The use of a discounted cash flow valuation model to determine estimated fair value is common practice in impairment testing. The key assumptions used in the discounted cash flow valuation model for impairment testing includes discount rates, growth rates, cash flow projections and terminal value rates. Discount rates are set by using the Weighted Average Cost of Capital (“WACC”) methodology. The WACC methodology considers market and industry data as well as Company specific risk factors for each reporting unit in determining the appropriate discount rates to be used. The discount rate utilized for each reporting unit is indicative of the return an investor would expect to receive for investing in such a business.

Operational management, considering industry and company-specific historical and projected data, develops growth rates, sales projections and cash flow projections for each reporting unit. Terminal value rate determination follows common methodology of capturing the present value of perpetual cash flow estimates beyond the last projected period assuming a constant WACC and low long-term growth rates. As an indicator that each reporting unit has been valued appropriately through the use of the discounted cash flow valuation model, the aggregate of all reporting units estimated fair value is reconciled to the total market capitalization of the Company.

The Company had 13 reporting units with goodwill as of the first day of the fourth quarter of fiscal 2010, the date of the last annual impairment test. The estimated fair values of each of the reporting units was substantially in excess of their respective carrying values (by more than 25 percent), and therefore no goodwill impairment was recorded. The Company performed a sensitivity analysis on the discount rate, which is a significant assumption in the calculation of fair values. With a one percentage point increase in the discount rate, the reporting units would continue to have fair values in excess of their respective carrying values.

Management tests indefinite-lived intangible assets for impairment at the asset level, as determined by appropriate asset valuation at the time of acquisition. The impairment test for indefinite-lived intangible assets consists of a comparison between the estimated fair values and carrying values. If the carrying amounts of intangible assets that have indefinite useful lives exceed their estimated fair values, an impairment loss will be recognized in an amount equal to the difference. Management utilizes the royalty savings valuation method to determine the estimated fair value for each indefinite-lived intangible asset. In this method, management estimates the royalty savings arising from the ownership of the intangible asset. The key assumptions used in estimating the royalty savings for impairment testing include discount rates, royalty rates, growth rates, sales projections and terminal value rates. Discount rates used are similar to the rates developed by the WACC methodology considering any differences in company-specific risk factors between reporting units and the indefinite-lived intangible assets. Royalty rates are established by management with the advice of valuation experts and periodically substantiated

-28-

by valuation experts. Operational management, considering industry and company-specific historical and projected data, develops growth rates and sales projections for each significant intangible asset. Terminal value rate determination follows common methodology of capturing the present value of perpetual sales estimates beyond the last projected period assuming a constant WACC and low long-term growth rates.

The discounted cash flow and royalty savings valuation methodologies require management to make certain assumptions based upon information available at the time the valuations are performed. Actual results could differ from these assumptions. Management believes the assumptions used are reflective of what a market participant would have used in calculating fair value considering the current economic conditions.

Stock Options: The Company accounts for the cost of its stock options in accordance with GAAP, which requires the measurement of compensation expense under the stock option plan to be based on the estimated fair value of the awards under the plan on the grant dates and amortizes the expense over the options’ vesting periods. Compensation expense is recorded over the service period using the straight-line method for service-based awards and in the service period corresponding to the performance target for performance-based awards. The Company estimates the fair value of all share-based payments using the Black-Scholes-Merton option pricing model which requires management to make certain assumptions. Management continuously reviews the following assumptions: risk-free interest rates, expected life of options, expected volatility of stock and expected dividend yield of stock. An increase or decrease in the assumptions or economic events outside management’s control could have an impact on the Company’s results of operations.

Environmental Matters: The Company is involved with environmental investigation and remediation activities at some of its currently and formerly owned sites and at a number of third-party sites. The Company accrues for environmental-related activities for which commitments or clean-up plans have been developed and for which costs can be reasonably estimated based on industry standards and professional judgment. All accrued amounts were recorded on an undiscounted basis. Environmental-related expenses include costs of investigation and remediation and fees paid to outside engineering, actuarial, consulting and law firms. Due to uncertainties surrounding environmental investigations and remediation activities, the Company’s ultimate liability may result in costs that are significantly higher than currently accrued.

Income Taxes: The Company estimated income taxes in each jurisdiction in which it operated. This involved estimating taxable earnings, specific taxable and deductible items, the likelihood of generating sufficient future taxable income to utilize deferred tax assets and possible exposures related to future tax audits. To the extent these estimates change, adjustments to deferred and accrued income taxes will be made in the period in which the changes occur. Historically, such adjustments have not been significant.

Changes in Results of Operations

Thirteen week period ended April 2, 2011 compared with the thirteen week period ended April 3, 2010.

• Net Sales. Net sales increased by $105.2 million, or 51.1%, to $311.3 million for the quarter ended April 2, 2011, from $206.1 million for the comparable quarter last year. Sales of $81.2 million, or 39.4%, resulted from the acquisitions of Dukes Aerospace and Semco Instruments in fiscal 2010 and McKechnie Aerospace and Talley Actuation in fiscal 2011. Organic sales increased by $24.0 million or 11.7% from the prior year. The organic sales growth was primarily due to an increase of $5.7 million in commercial OEM sales, and an increase of $18.1 million in commercial aftermarket sales resulting primarily from higher volumes given an improving market demand for aftermarket products. Defense sales decreased slightly by $1.8 million for the quarter ended April 2, 2011 compared to the quarter ended April 3, 2010.

• Cost of Sales and Gross Profit. Cost of sales increased by $61.9 million, or 68.1%, to $152.8 million for the quarter ended April 2, 2011 from $90.9 million for the comparable quarter last year. The increase in the dollar amount of cost of sales was primarily due to increased volume associated with the net sales from acquisitions and the organic sales growth discussed above along with an increase in inventory purchase accounting adjustments and acquisition integration costs.

-30-

Gross profit as a percentage of sales decreased to 50.9% for the thirteen week period ended April 2, 2011 from 55.9% for the thirteen week period ended April 3, 2010. The dollar amount of gross profit increased by $43.4 million, or 37.6%, to $158.6 million for the thirteen week period ended April 2, 2011 from $115.2 million for the thirteen week period ended April 3, 2010. The increase in the amount of gross profit was primarily due to the following items:

• Sales of $81.2 million from the acquisitions indicated above contributed gross profit of approximately $23 million for the quarter ended April 2, 2011, which includes the acquisition-related costs (inventory purchase accounting adjustments and acquisition integration costs) incurred in connection with those acquisitions amounting to $14.0 million. These acquisitions diluted gross profit as a percentage of sales for the quarter ended April 2, 2011 by approximately 8 percentage points.

• Organic sales growth described above, favorable product mix and favorable product pricing on our proprietary products resulted in increased gross profit of approximately $20 for the thirteen week period ended April 2, 2011.

• Selling and Administrative Expenses. Selling and administrative expenses increased by $10.2 million to $33.8 million, or 10.9% of sales, for the quarter ended April 2, 2011 from $23.6 million, or 11.4% of sales, for the comparable quarter last year. The increase is primarily due to higher selling and administrative expenses relating to recent acquisitions of approximately $8.2 million and higher general professional fees.

• Amortization of Intangibles. Amortization of intangibles increased to $11.6 million for the quarter ended April 2, 2011 from $3.6 million for the comparable quarter last year. The net increase of $8.0 million was primarily due to amortization expense related to the additional identifiable intangible assets recognized in connection with acquisitions during the last twelve months.

• Refinancing Costs. Refinancing costs of $1.6 million were recorded during the quarter ended April 2, 2011 as a result of the redemption of the remaining $31.4 million outstanding 2014 Notes.

• Interest Expense-net. Interest expense increased $25.7 million, or 90.5%, to $54.1 million for the quarter ended April 2, 2011 from $28.4 million for the comparable quarter last year. The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $3.15 billion for the quarter ended April 2, 2011 and approximately $1.78 billion for the quarter ended April 3, 2010. The increase in borrowings was due to the debt refinancing transactions and the acquisition financing related to McKechnie Aerospace which occurred in December 2010.

• Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 36.1% for the quarter ended April 2, 2011 compared to 36.2% for the quarter ended April 3, 2010.

• Income from discontinued operations. Income from discontinued operations includes loss from discontinued operations through the date of sale and the after-tax gain on sale of $21.0 million recorded during the quarter ended April 2, 2011.

• Net Income. Net income increased $17.8 million, or 46.7%, to $55.8 million for the quarter ended April 2, 2011 compared to net income of $38.0 million for the quarter ended April 3, 2010, primarily as a result of the factors referred to above.

• Earnings per Share. The basic and diluted earnings per share were $1.05 for the quarter ended April 2, 2011 and $0.72 per share for the quarter ended April 3, 2010. The quarter ended April 2, 2011 comprises basic and diluted earnings per share from continuing operations of $0.69 and basic and diluted earnings per share from discontinued operations of $0.36.

Twenty-six week period ended April 2, 2011 compared with the twenty-six week period ended April 3, 2010.

• Net Sales. Net sales increased by $157.8 million, or 40.4%, to $548.2 million for the twenty-six week period ended April 2, 2011, from $390.4 million for the comparable period last year. Sales of $114.3 million, or 29.3%, resulted from the acquisitions of Dukes Aerospace and Semco Instruments in fiscal 2010 and McKechnie Aerospace and Talley Actuation in fiscal 2011. Organic sales increased by $43.5 million or 11.1% from the prior year. The organic sales growth was primarily due to an increase of $9.5 million in commercial OEM sales, and an increase of $33.6 million in commercial aftermarket sales resulting primarily from higher volumes given an improving market demand for aftermarket products. Defense sales decreased slightly by $1.7 million for the twenty-six week period ended April 2, 2011 compared to the quarter ended April 3, 2010.

• Cost of Sales and Gross Profit. Cost of sales increased by $90.0 million, or 52.3%, to $262.1 million for the twenty-six week period ended April 2, 2011 from $172.1 million for the comparable period last year. The increase in the dollar amount of cost of sales was primarily due to increased volume associated with the net sales from acquisitions and the organic sales growth discussed above along with an increase in inventory purchase accounting adjustments and acquisition integration costs.

Gross profit as a percentage of sales decreased to 52.2% for the twenty-six week period ended April 2, 2011 from 55.9% for the twenty-six week period ended April 3, 2010. The dollar amount of gross profit increased by $67.9 million, or 31.1%, to $286.2 million for the twenty-six week period ended April 2, 2011 from $218.3 million for the twenty-six week period ended April 3, 2010. The increase in the amount of gross profit was primarily due to the following items:

• Sales of $114.3 million from the acquisitions indicated above contributed gross profit of approximately $34 million for the twenty-six week period ended April 2, 2011, which includes the acquisition-related costs (inventory purchase accounting adjustments and acquisition integration costs) incurred in connection with those acquisitions amounting to $16.5 million. These acquisitions diluted gross profit as a percentage of sales for the twenty-six week period ended April 2, 2011 by approximately 6 percentage points.

• Organic sales growth described above, favorable product mix and favorable product pricing on our proprietary products resulted in increased gross profit of approximately $34 for the twenty-six week period ended April 2, 2011.

• Selling and Administrative Expenses. Selling and administrative expenses increased by $18.4 million to $64.5 million, or 11.8% of sales, for the twenty-six week period ended April 2, 2011 from $46.1 million, or 11.8% of sales, for the comparable period last year. The increase is primarily due to higher selling and administrative expenses relating to recent acquisitions of approximately $13.7 million and higher general professional fees.

• Amortization of Intangibles. Amortization of intangibles increased to $15.9 million for the twenty-six week period ended April 2, 2011 from $7.7 million for the comparable period last year. The net increase of $8.2 million was primarily due to amortization expense related to the additional identifiable intangible assets recognized in connection with acquisitions during the last twelve months.

• Refinancing Costs. Refinancing costs were recorded in December 2010 as a result of the refinancing of TransDigm’s entire debt structure. The charge of $72.4 million consisted of the premium of $42.4 million paid to redeem our 7 ³/4% senior subordinated notes, the write-off of debt issue costs and unamortized note premium and discount of $25.7 million, and the settlement of the interest rate swap agreement and other expenses of $4.3 million.

• Interest Expense-net. Interest expense increased $29.8 million, or 52.3%, to $86.7 million for the twenty-six week period ended April 2, 2011 from $56.9 million for the comparable period last year. The net increase in

-32-

interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $2.65 billion for the twenty-six week period ended April 2, 2011 and approximately $1.78 billion for the twenty-six week period ended April 3, 2010. The increase in borrowings was due to the debt refinancing transactions and the acquisition financing related to McKechnie Aerospace which occurred in December 2010. The weighted average interest rate on total borrowings outstanding at April 2, 2011 was approximately 5.9%.

• Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 36.5% for the twenty-six week period ended April 2, 2011 compared to 36.0% for the twenty-six week period ended April 3, 2010.

• Income from discontinued operations. Income from discontinued operations includes loss from discontinued operations from the McKechnie Aerospace acquisition date through the date of sale of the fastener business and the after-tax gain on sale of $21.0 million recorded during the twenty-six week period ended April 2, 2011.

• Net Income. Net income decreased $20.3 million, or 29.6%, to $48.5 million for the twenty-six week period ended April 2, 2011 compared to net income of $68.8 million for the twenty-six week period ended April 3, 2010, primarily as a result of the factors referred to above.

• Earnings per Share. The basic and diluted earnings per share were $0.86 for the twenty-six week period ended April 2, 2011 and $0.73 per share for the twenty-six week period ended April 3, 2010. The twenty-six week period ended April 2, 2011 comprises basic and diluted earnings per share from continuing operations of $0.50 and basic and diluted earnings per share from discontinued operations of $0.36. Net income for the twenty-six week period ended April 2, 2011 of $48.5 million was decreased by an allocation of dividends to participating securities of $2.8 million resulting in net income available to shareholders of $45.6 million. Due to the special cash dividend declared and paid during the quarter ended January 2, 2010, the net income for the twenty-six week period ended April 3, 2010 of $68.8 million was reduced by an allocation of dividends to participating securities of $30.3 million resulting in net income applicable to common shareholders of $38.5 million.

Backlog

As of April 2, 2011, the Company estimated its sales order backlog at $670.0 million compared to an estimated sales order backlog of $429.5 million as of April 3, 2010. This increase in backlog is primarily due to the purchase orders acquired in connection with the acquisitions of Semco Instruments, McKechnie Aerospace and Talley Actuation, discussed above, totaling approximately $185.2 million as of April 2, 2011. The majority of the purchase orders outstanding as of April 2, 2011 are scheduled for delivery within the next twelve months. Purchase orders may be subject to cancellation or deferral by the customer prior to shipment. The level of unfilled purchase orders at any given date during the year will be materially affected by the timing of the Company’s receipt of purchase orders and the speed with which those orders are filled. Accordingly, the Company’s backlog as of April 2, 2011 may not necessarily represent the actual amount of shipments or sales for any future period.

Foreign Operations

Although we manufacture substantially all of our products in the United States, we manufacture some products in Malaysia, Mexico and Belgium. We sell our products in the United States, as well as in foreign countries. A number of risks inherent in international operations could have a material adverse effect on our results of operations, including currency fluctuations, difficulties in staffing and managing multi-national operations, general economic and political uncertainties and potential for social unrest in countries in which we operate, limitations on our ability to enforce legal rights and remedies, restrictions on the repatriation of funds, change in trade policies, tariff regulation, difficulties in obtaining export and import licenses and the risk of government financed competition.

There can be no assurance that foreign governments will not adopt regulations or take other action that would have a direct or indirect adverse impact on the business or market opportunities of the Company within such governments’

-33-

countries. Furthermore, there can be no assurance that the political, cultural and economic climate outside the United States will be favorable to our operations and growth strategy.

Liquidity and Capital Resources

Operating Activities. The Company generated $129.2 million of cash from operating activities during the twenty-six week period ended April 2, 2011 compared to $83.8 million during the twenty-six week period ended April 3, 2010. The net increase of $45.4 million was due primarily due to an increase in income from operations and favorable working capital management during the twenty-six week period ended April 2, 2011.

Investing Activities. Cash used in investing activities was $1,130.6 million during the twenty-six week period ended April 2, 2011, consisting primarily of the acquisitions of McKechnie Aerospace and Talley Actuation and capital expenditures of $8.4 million offset by the cash proceeds on the sale of the fastener business of $240.0 million. Cash used in investing activities was $102.8 million during the twenty-six week period ended April 3, 2010 consisting primarily of the acquisition of Dukes Aerospace and capital expenditures of $6.9 million.

Financing Activities. Cash provided by financing activities during the twenty-six week period ended April 2, 2011 was $1,272.7 million, which comprised $1,260.6 million of net proceeds from the refinancing of our entire debt structure, $3.9 million repayment on our new senior secured credit facility, $2.8 million of dividends and dividend equivalent payments, and $18.7 million of cash for tax benefits related to share-based payment arrangements and from the exercise of stock options. Cash provided by financing activities during the twenty-six week period ended April 3, 2010 was $16.2 million, which comprised $404.5 million of net proceeds from the issuance of the 7 ³/4% senior subordinated notes, $404.9 million of dividends and dividend equivalent payments, and $16.6 million of cash for tax benefits related to share-based payment arrangements and from the exercise of stock options.

Description of New Senior Secured Credit Facility and Indenture

In December 2010, TransDigm entered into a Senior Secured Credit Facility, which consisted of a $1.55 billion term loan facility and a $245 million revolving credit facility (collectively, the “Existing Senior Secured Credit Facility”). The proceeds of the term loan were used to pay the purchase price of and related transaction expenses associated with the acquisition of McKechnie Aerospace and repay a portion of the amounts outstanding under the previous senior secured credit facility.

On February 14, 2011, TransDigm Inc. entered into a new Senior Secured Credit Facility which provides for $1.55 billion term loan facility (the “New Senior Secured Credit Facility”), which was fully drawn on February 14, 2011. The New Senior Secured Credit Facility replaced the term loan under the Existing Senior Secured Credit Facility and modified certain terms of the original agreement including extending the maturity date of the term loan and modifying the interest rate provisions.

On March 25, 2011, TransDigm entered into Amendment No. 1 (the “Amendment”) to the Existing Senior Secured Credit Facility. The Amendment provides for a modification to certain terms of the permitted indebtedness covenant contained in the Existing Senior Secured Credit Facility to modify the requirements for incurring certain additional senior indebtedness.

The applicable interest rate on the term loan at April 2, 2011 was 4.0%. At April 2, 2011, the Company had $7.0 million letters of credit outstanding and $238.0 of borrowings available under the Existing Senior Secured Credit Facility.

Under the New Senior Secured Credit Facility, the term loan matures in February 2017. Under the Existing Senior Secured Credit Facility, the revolving credit facility matures in December 2015. The term loan under the New Senior Secured Credit Facility requires quarterly principal payments that began on March 31, 2011.

The term loan under the New Senior Secured Credit Facility requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as therein defined), commencing 90 days after the end of each fiscal year,

-34-

commencing with the fiscal year ending September 30, 2012, subject to certain exceptions. In addition, subject to certain exceptions (including, with respect to asset sales, the reinvestment in productive assets), TransDigm will be required to prepay the loans outstanding under the term loan facility at 100% of the principal amount thereof, plus accrued and unpaid interest, with the net cash proceeds of certain asset sales and issuance or incurrence of certain indebtedness. In addition, if, prior to February 14, 2012, the principal amount of the term loans are (i) prepaid substantially concurrently with the incurrence by TD Group, TransDigm or any its subsidiaries of new bank loans that have an effective yield lower than the yield in effect on the term loans so prepaid or (ii) received by a lender due to a mandatory assignment following the failure of such lender to consent to an amendment of the New Senior Secured Credit Facility that has the effect of reducing the effective interest rate with respect to the term loans, such prepayment or receipt shall be accompanied by a premium of 1.0%.

Long-term financing arrangements also include $1.6 billion of aggregate principal amount of 7 ³/4% senior subordinated notes (discussed further below). Such notes do not require principal payments prior to their maturity in December 2018.

New 7 ³/4% Senior Subordinated Notes due 2018

In December 2010, TransDigm issued $1.6 billion in aggregate principal amount of its 7 ³/4% Senior Subordinated Notes due 2018 (the “2018 Notes”) at an issue price of 100% of the principal amount. The 2018 Notes represent unsecured obligations of TransDigm Inc. ranking subordinate to TransDigm Inc.’s senior debt, as defined in the indenture governing the 2018 Notes (the “Indenture”). Interest under the 2018 Notes is payable semi-annually.

TransDigm utilized a portion of the proceeds from the 2018 Notes to purchase approximately $968.6 million aggregate principal amount of its 7 ³/4% Senior Subordinated Notes due 2014 (the “2014 Notes”) representing all such 2014 Notes that were validly tendered and not validly withdrawn at or prior to the consent expiration deadline pursuant to TransDigm’s previously announced cash offers to purchase (“Tender Offers”) any and all of its outstanding 2014 Notes in December 2010. TransDigm also received consents from holders of the required majority of the principal amount of the 2014 Notes to, among other modifications, eliminate substantially all of the restrictive covenants and certain events of default in the indentures governing the 2014 Notes.

Remaining proceeds from the 2018 Notes were utilized to pay off the remaining outstanding balance under the previous senior secured credit facility and for general corporate purposes.

During January 2011, TransDigm redeemed the remaining $31.4 million outstanding under the 2014 Notes.

The Company recorded refinancing costs of $72.4 million during the twenty-six week period ended April 2, 2011 representing one-time charges resulting from the refinancing of TransDigm’s entire debt structure. The charge consisted of the premium of $42.4 million paid to redeem our 2014 Notes, the write-off of debt issue costs and unamortized note premium and discount of $25.7 million, and the settlement of the interest rate swap agreement and other expenses of $4.3 million.

Certain Restrictive Covenants in Our Debt Documents

The New Senior Secured Credit Facility and the Indenture contain restrictive covenants that, among other things, limit the incurrence of additional indebtedness, the payment of dividends, transactions with affiliates, asset sales, acquisitions, mergers and consolidations, liens and encumbrances, and prepayments of other indebtedness. A breach of any of the covenants or an inability to comply with the required leverage ratio could result in a default under the New Senior Secured Credit Facility or the Indenture. If any such default occurs, the lenders under the New Senior Secured Credit Facility and the holders of the 2018 Notes may elect to declare all outstanding borrowings, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. The lenders under the New Senior Secured Credit Facility also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, following an event of default under the New Senior Secured Credit Facility, the lenders thereunder will have the right to proceed against the collateral granted to them to secure the debt, which includes our available cash, and they will also have the right to prevent us from making debt service payments on the 2018 Notes.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Our main exposure to market risk relates to interest rates. Our financial instruments that are subject to interest rate risk principally include fixed-rate and floating-rate long-term debt. At April 2, 2011, we had borrowings under our Senior Secured Credit Facility of $1.51 billion that were subject to interest rate risk. Borrowings under our Senior Secured Credit Facility bear interest, at our option, at a rate equal to either an alternate base rate or an adjusted LIBO rate for a one-, two-, three- or six-month (or to the extent available to each lender, nine- or twelve-month) interest period chosen by us, in each case, plus an applicable margin percentage. Accordingly, the Company’s cash flows and earnings will be exposed to the market risk of interest rate changes resulting from variable rate borrowings under our Senior Secured Credit Facility. The effect of a hypothetical one percentage point increase in interest rates would increase the annual interest costs under our New Senior Secured Credit Facility by approximately $15.1 million based on the amount of outstanding borrowings at April 2, 2011. The weighted average interest rate on the $1.51 billion of borrowings under our Senior Secured Credit Facility on April 2, 2011 was 4.0%.

-35-

The fair value of the $1.51 billion aggregate principal amount of borrowings under our New Senior Secured Credit Facility is exposed to the market risk of interest rates. The estimated fair value of such term loan approximated $1.56 billion at April 2, 2011 based upon information provided to the Company from its agent under the credit facility. The fair value of the $1.60 billion aggregate principal amount of our 7 ³/4% senior subordinated notes due 2018 is exposed to the market risk of interest rate changes. The estimated fair value of such notes approximated $1.72 billion at April 2, 2011 based upon quoted market rates.

ITEM 4. CONTROLS AND PROCEDURES

As of April 2, 2011, TD Group carried out an evaluation, under the supervision and with the participation of TD Group’s management, including its Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial and Accounting Officer), of the effectiveness of the design and operation of TD Group’s disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that TD Group’s disclosure controls and procedures are effective to ensure that information required to be disclosed by TD Group in the reports it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported, within the time periods specified by the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to TD Group’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, TD Group’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures. There have been no significant changes in TD Group’s internal controls or other factors that could significantly affect the internal controls subsequent to the date of TD Group’s evaluations.

Changes in Internal Control over Financial Reporting

On December 6, 2010, we acquired McKechnie Aerospace. McKechnie Aerospace operated under its own set of systems and internal controls and we are currently maintaining those systems and much of that control environment until we are able to incorporate McKechnie Aerospace’s processes into our own systems and control environment. We currently expect to complete the incorporation of McKechnie Aerospace’s operations into our systems and control environment in fiscal 2011. There were no other changes to our internal controls over financial reporting that could have a material effect on our financial reporting during the quarter ended April 2, 2011.
