TRANSDIGM GROUP INCORPORATED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

THIRTEEN AND TWENTY-SIX WEEK PERIODS ENDED APRIL 1, 2006 AND APRIL 2, 2005 (UNAUDITED)

1. DESCRIPTION OF THE BUSINESS AND MERGER

Description of the Business—On January 19, 2006 TD Holding Corporation changed its legal name to TransDigm Group Incorporated (“TD Group”). This change was effected to ensure that investors recognize that TD Group is the ultimate owner of the TransDigm group of operating companies, as the TransDigm name is recognized in the industry in which TD Group’s subsidiaries operate. TD Group, through its wholly-owned subsidiary TransDigm Holding Company (“TransDigm Holdings”), and 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 AeroControlex and Adel Wiggins Groups, along with its wholly-owned operating subsidiaries, MarathonNorco Aerospace, Inc., Adams Rite Aerospace, Inc., Champion Aerospace Inc., Avionic Instruments, Inc. and Skurka Aerospace Inc. (collectively, with TD Group and TransDigm Holdings, the “Company” or “TransDigm”) offers a broad range of proprietary aerospace components. Major product offerings, substantially all of which are ultimately provided to end-users in the aerospace industry, include ignition systems and components, gear pumps, mechanical/electromechanical actuators and controls, NiCad batteries/chargers, power conditioning devices, hold open rods and locking devices, engineered connectors, engineered latches, cockpit security devices, lavatory hardware and components, specialized AC/DC electric motors and specialized valving.

TD Group was incorporated on July 8, 2003 by outside investors to acquire control of TransDigm Holdings through the Merger described below and had no operations prior to the Merger. TD Group has no material assets or operations other than its 100% ownership of TransDigm Holdings, which in turn has no material assets or operations other than its 100% ownership of TransDigm Inc.

Initial Public Offering—On March 20, 2006, TD Group completed an initial public offering (“IPO”) of its common stock (see Note 11). As a result of the IPO, TD Group’s common stock is publicly traded on the New York Stock Exchange under the ticker symbol “TDG”.

On March 14, 2006, TD Group effected a 149.6 for 1 stock split and, in conjunction therewith, amended and restated its certificate of incorporation to increase the number of authorized shares of common stock and preferred stock. All common shares and per common share amounts in these condensed consolidated financial statements prior to March 14, 2006 have been retroactively adjusted for all periods presented to give effect to the stock split, including reclassifying an amount equal to the increase in par value from additional paid-in capital to common stock.

Merger—On July 22, 2003, an entity formed by Warburg Pincus Private Equity VIII, L.P. (“Warburg Pincus”) merged with and into TransDigm Holdings, with TransDigm Holdings continuing as the surviving corporation as a wholly-owned subsidiary of a newly formed corporation controlled by Warburg Pincus, TD Group (the “Merger”).

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, 2005 included in its prospectus dated March 14, 2006. The September 30, 2005 condensed consolidated balance sheet was derived from the TD Group’s audited financial statements. The results of operations for the thirteen and twenty-six week periods ended April 1, 2006 are not necessarily indicative of the results to be expected for the full year.

3. NEW ACCOUNTING STANDARDS

During December 2004, the Financial Accounting Standards Board (the “FASB”) issued Statement No. 123(R), Share Based Payment (“SFAS 123(R)”), which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. The Company anticipates adopting this pronouncement effective October 1, 2006. The Company anticipates that the adoption of this pronouncement will not have a material impact on its consolidated financial position or results of operations as SFAS 123(R) will be applied to option grants issued subsequent to December 20, 2005.

4. ACQUISITIONS

Eaton Motors – On June 30, 2005, TransDigm Inc., through its wholly-owned Skurka Aerospace Inc. subsidiary, acquired an aerospace motor product line from Eaton Corporation for $9.6 million in cash. The Eaton business has been a long-time supplier of aerospace motors and related products. The motor products are used on a range of commercial aircraft, as well as military programs. The product line’s proprietary products, market position, and aftermarket content fit well with TransDigm’s overall direction. The acquired business was consolidated into Skurka’s existing aerospace motor business in Camarillo, California. The Company expects that the $4.8 million of goodwill recognized for the acquisition will be deductible for income tax purposes.

Fluid Regulators— On January 28, 2005, TransDigm acquired all of the outstanding capital stock of Fluid Regulators Corporation, a wholly-owned subsidiary of Esterline Technologies Corporation, for $23.5 million in cash, net of a purchase price adjustment of $0.5 million received in April 2005. Fluid Regulators designs and manufactures highly engineered flight control and pressure valves used in hydraulic, fuel, lubrication and related applications. The products are used on a wide range of commercial and regional aircraft as well as many corporate and military aircraft. Fluid Regulator’s product characteristics and market position fit well with TransDigm’s overall direction. In an attempt to reduce the combined operating costs of Fluid Regulators and the AeroControlex division of TransDigm Inc., Fluid Regulators was merged into TransDigm Inc. on September 30, 2005. The Company expects that the $15.7 million in goodwill recognized in accounting for the acquisition will not be deductible for income tax purposes.

Skurka— On December 31, 2004, TransDigm Inc., through its wholly-owned Skurka Aerospace Inc. subsidiary, acquired certain assets and assumed certain liabilities of Skurka Engineering Company (“Skurka”) for $30.7 million in cash. Skurka designs and manufactures engineered aerospace components, primarily AC/DC electric motors and transducers. The products are used on a wide range of commercial and military aircraft, ships and ground vehicles. Skurka’s product characteristics and market position fit well with TransDigm’s overall direction. The Company expects that the $20.7 million of goodwill recognized in accounting for the acquisition will be deductible for income tax purposes.

The Company accounted for the acquisitions of Skurka, Fluid Regulators and the motor product line (collectively, the “Acquisitions”) as purchases and included the results of operations of the Acquisitions in its consolidated financial statements from the effective date of each acquisition. Proforma net sales and results of operations for the Acquisitions, had the Acquisitions occurred at the beginning of the thirteen and twenty-six week periods ended April 2, 2005, are not significant and, accordingly, are not provided.

8. DEBT

On November 10, 2005, TD Group closed on a $200 million loan facility (the “TD Group Loan Facility”). The TD Group Loan Facility matures on November 10, 2011. The principal amount of the indebtedness outstanding under the TD Group Loan Facility is not amortized and, therefore, the entire balance thereof is payable on maturity on November 10, 2011, subject to certain prepayment requirements. On November 10, 2005, TD Group used the net proceeds from the TD Group Loan Facility of approximately $193.8 million, together with substantially all of the proceeds received from a dividend payment from TransDigm Holdings to prepay the entire outstanding principal amount and all accrued and unpaid interest on its former senior unsecured promissory notes totaling approximately $262.7 million (see Note 10).

The interest rates per annum applicable to the loans under the TD Group Loan Facility are equal to an adjusted LIBO rate for three-month interest periods plus an applicable margin percentage. The adjusted LIBO rate is determined by reference to settlement rates established for deposits in dollars in the London interbank market for three-month periods as adjusted for the maximum reserve percentages established by the Board of Governors of the United States Federal Reserve to which TD Group’s lenders are subject. Prior to the IPO, the applicable margin percentage was a percentage per annum equal to 5%. For any day on or after the IPO (the “Trigger Date”) until the day that is one year from the Trigger Date, the applicable margin percentage is a percentage per annum equal to 5.5%, and for any day on or after the date that is one year from the Trigger Date, the applicable margin percentage is a percentage per annum equal to 6%. The interest rate on the TD Group Loan Facility at April 1, 2006 was 10.2%

The TD Group Loan Facility is subject to mandatory prepayment upon the occurrence of a Change in Control (as defined in the TD Group Loan Facility) and, subject to certain exceptions, in connection with certain asset sales. The TD Group Loan Facility is unsecured and is not guaranteed by TransDigm Holdings or any of its direct or indirect subsidiaries. The agreement also contains a number of restrictive covenants restricting or limiting the ability of TD Group and its subsidiaries to, among other things, incur or guarantee additional debt, incur liens, issue preferred stock of restricted subsidiaries, pay dividends or make other distributions, purchase or redeem capital stock, make certain investments, enter into arrangements that restrict dividends from restricted subsidiaries, engage in transactions with affiliates, sell or otherwise dispose of assets and merge into or consolidate with another entity. TD Group is in compliance with all of the covenants contained in the TD Group Loan Facility.

In connection with closing of the TD Group Loan Facility, on November 10, 2005, TransDigm Inc. entered into an amendment to the amended and restated credit agreement (the “Amended and Restated Senior Credit Agreement”), dated as of April 1, 2004 (the “Amendment”). The Amendment, among other things, authorizes TransDigm Holdings, so long as certain conditions are satisfied, to (i) make Bonus and Dividend Payments (as defined therein) and (ii) pay dividends to TD Group so long as the proceeds of such dividends are used, directly or indirectly, to pay interest in respect of the indebtedness outstanding under the TD Group Loan Facility. In addition, the Amendment authorizes TransDigm Inc. to make distributions to TransDigm Holdings to enable TransDigm Holdings to make such dividend payments to TD Group.

9. RETIREMENT PLANS

Defined Benefit Pension Plans – The Company has two non-contributory defined benefit pension plans, which together cover certain union employees. The plans provide benefits of stated amounts for each year of service. The Company’s funding policy is to contribute actuarially determined amounts allowable under Internal Revenue Service regulations. The plans’ assets consist primarily of guaranteed investment contracts with an insurance company.

The components of net periodic benefit cost are detailed below (in thousands):

	Thirteen Weeks Ended						Twenty-Six Weeks Ended
	April 1, 2006			April 2, 2005			April 1, 2006			April 2, 2005
Service cost	$	23		$	21		$	46		$	42
Interest cost		107			96			214			192
Expected return on plan assets		(65	)		(67	)		(130	)		(134	)
Net amortization and deferral		6			8			12			16
	$	71		$	58		$	142		$	116

Deferred Compensation Plans—Certain management personnel of the Company participated in one or both of two deferred compensation plans of TD Group that were established in connection with the Merger. On November 10, 2005 and December 16, 2005, the Board of Directors of TD Group approved the termination of these deferred compensation plans. TD Group adopted the TD Holding Corporation 2005 New Management Deferred Compensation Plan (the “New Management Deferred Compensation Plan”) in December 2005 in connection with certain new requirements under Section 409A of the Internal Revenue Code of 1986, as amended. The New Management Deferred Compensation Plan is for the benefit of certain management personnel of the Company who were granted new management options under the TD Group 2003 stock option plan. The New Management Deferred Compensation Plan provides that a participant’s deferred compensation account is fully distributable upon the earlier of: December 31, 2008 or a Change in Control (as defined in the plan). On December 16, 2005, TD Group’s Board of Directors approved contributions of $6.2 million, in the aggregate, to participant account balances under the New Management Deferred Compensation Plan. The cost of the plans totaled $0.5 million, $(2.5) million, $1.4 million and $2.8 million for the thirteen and twenty-six week periods ended April 1, 2006 and April 2, 2005, respectively. The amount recognized during the twenty-six week period ended April 1, 2006 includes a reversal of previously recorded charges of $3.8 million resulting from the termination of the two deferred compensation plans of TD Group discussed above. The obligations under the New Management Deferred Compensation Plan represent obligations of TD Group and are not guaranteed by TransDigm Holdings or any of its subsidiaries.

10. DIVIDEND AND BONUS PAYMENTS

On November 10, 2005, in connection with the closing of the TD Group Loan Facility (see Note 8), TransDigm Inc. paid a cash dividend to TransDigm Holdings and made bonus payments to certain members of TransDigm’s management. The aggregate amount of the cash dividend and bonus payments made by TransDigm Inc. was approximately $104 million. TransDigm Holdings used all of the proceeds received by it from the payment of the cash dividend from TransDigm Inc. to pay a cash dividend to TD Group. On November 10, 2005, TD Group used the net proceeds received from the TD Group Loan Facility of approximately $193.8 million together with substantially all of the proceeds received from the dividend payment from TransDigm Holdings to (i) prepay the entire outstanding principal amount and all accrued and unpaid interest on its senior unsecured promissory notes that were issued by it in connection with the Merger in July 2003, with all such payments totaling approximately $262.7 million, (ii) make a distribution to participants under the TD Holding Corporation 2003 Rollover Deferred Compensation and Phantom Stock Unit Plan (the “Rollover Deferred Compensation Plan”) of their vested deferred compensation account balances, with all such distributions totaling approximately $23.0 million, and (iii) make a distribution to participants under the TD Holding Corporation 2003 Management Deferred Compensation and Phantom Stock Unit Plan (the “Management Deferred Compensation Plan”) of their vested and a portion of their unvested deferred compensation account balances, with all such distributions totaling approximately $3.0 million. In connection with the distributions under the Rollover Deferred Compensation Plan and the Management Deferred Compensation Plan, the Board of Directors of TD Group approved the termination of the Rollover Deferred Compensation Plan and the Management

Deferred Compensation Plan, with such terminations becoming effective on November 10, 2005 and December 16, 2005, respectively.

The approximately $6.2 million in aggregate bonuses were allocated to each employee receiving a bonus based on the aggregate number of shares of the Company’s common stock underlying rollover options and new management options granted to all employees receiving a bonus.

11. CAPITAL STOCK

Authorized capital stock of TD Group consists of 224.4 million shares of $.01 par value common stock and 149.6 million shares of $.01 par value preferred stock.

On December 19, 2005, TD Group filed a registration statement on Form S-1 with the SEC for its proposed IPO in connection with the sale by certain selling stockholders of TD Group’s common stock. The registration statement was declared effective by the Securities and Exchange Commission on March 14, 2006 at a public offering price of $21.00 per share. The number of shares offered by the selling stockholders was 10,954,570. The selling stockholders also granted the underwriters a 30-day option to purchase up to 1,643,186 additional shares to cover any over-allotments. The underwriters’ over-allotment option was exercised on March 15, 2006. The proceeds from the sale of shares of TD Group’s common stock sold in the IPO were solely for the account of the selling stockholders. TD Group did not receive any proceeds from the sale of shares by the selling stockholders.

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 the “Company” “TransDigm,” “we,” “us” or “our” are to TD Group, TransDigm Holdings, together with TransDigm Inc. and its subsidiaries. References to “TransDigm Holdings” are to TransDigm Holding Company, a wholly owned subsidiary of TD Group which holds all of the outstanding capital stock of TransDigm Inc.

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 occurrence of future terrorist attacks.

• Our business is sensitive to the number of flight hours that our customers’ planes spend aloft, the size and age of the worldwide aircraft fleet, and to our customers’ profitability. These items are, in turn, affected by general economic conditions.

• Our sales to manufacturers of new large aircraft are cyclical, and a downturn in sales to these manufacturers may adversely effect us.

• We rely heavily on certain customers for much of our sales.

• We generally do not have guaranteed future sales of our products. Further, we enter into fixed price contracts with some of our customers, so we take the risk for cost overruns.

• U.S military spending is dependent upon the U.S. defense budget.

• We are subject to certain unique business risks as a result of supplying equipment and services to the U.S Government. In addition, government contracts contain unfavorable termination provisions and are subject to modification and audit.

• Certain of our divisions and subsidiaries have been subject to a pricing review by the DOD Office of Inspector General.

• Our business may be adversely affected if we would lose our government or industry approvals or if more stringent government regulations were enacted, or if industry oversight is increased.

• Our substantial leverage could adversely affect our financial health.

• The terms of the Amended and Restated Senior Credit Agreement, the Indenture governing the 8 ³/8% Senior Subordinated Notes and the TD Group Loan Facility may restrict our current and future operations.

• We are dependent on our highly trained employees and any work stoppage or difficulty hiring similar employees would adversely affect our business.

11

• Our business is dependent on the availability of certain components and raw materials that we buy from suppliers.

• We are subject to a number of environmental laws and regulations, and we could incur substantial costs as a result of violations under such environmental laws and regulations.

• We intend to pursue future acquisitions. Our business may be adversely affected if we cannot consummate acquisitions on satisfactory terms or if we cannot effectively integrate acquired operations.

• We have recorded a significant amount of intangible assets, which may never generate the returns we expect.

• We face significant competition.

• We could be adversely affected if one of our components causes an aircraft to crash.

• We do not intend to pay regular dividends.

• Our stock price may be volatile and your investment in our common stock could suffer a decline in value.

• Future sales of our common stock in the public market could lower our share price.

• Our principal stockholder and its affiliates will be able to influence matters requiring stockholder approval.

• We are exempt from certain corporate governance requirements since we are a “controlled company” within the meaning of New York Stock Exchange rules.

• Our corporate documents and Delaware law contain provisions that could discourage, delay, or prevent a change in control.

Please refer to the other information included in this Quarterly Report on Form 10-Q and to the Registration Statement on Form S-1 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 ignition systems and components, gear pumps, mechanical/electromechanical actuators and controls, NiCad batteries/chargers, power conditioning devices, hold-open rods and locking devices, engineered connectors, engineered latches and cockpit security devices, lavatory hardware and components, specialized AC/DC electric motors and specialized valving. Each of these product offerings consists 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 2006, we generated net sales of $108.3 million and net income of $14.3 million. EBITDA As Defined was $48.1 million, or 44.4% of net sales. Please see below for certain information regarding EBITDA and EBITDA As Defined, including a reconciliation of EBITDA and EBITDA As Defined to net income.

Recent Developments

Dividend and Bonus Payments

On November 10, 2005, TD Group closed on the $200 million TD Group Loan Facility. In connection with the closing of the TD Group Loan Facility, on November 10, 2005, TransDigm Inc. and TransDigm Holdings entered into the Amendment to the Amended and Restated Senior Credit Agreement. Among other things, the Amendment authorized (i) the payment of the cash dividends by TransDigm Inc. and TransDigm Holdings referred to in the immediately following paragraph and (ii) TransDigm Inc. and TransDigm Holdings to make certain distributions to TD Group from time to time, so long as certain conditions are satisfied and the proceeds of such distributions to TD Group are used, directly or indirectly, by TD Group to pay interest in respect of the indebtedness outstanding under the TD Group Loan Facility.

12

In connection with the closing of the TD Group Loan Facility, TransDigm Inc. paid a cash dividend of approximately $98.0 million to TransDigm Holdings and made bonus payments of approximately $6.2 million to certain members of our management (which bonus payments were in addition to amounts paid to certain members of our management under our deferred compensation plans, as described below). TransDigm Holdings used all of the proceeds received by it from TransDigm Inc. to pay a cash dividend to TD Group. On November 10, 2005, TD Group used the net proceeds received from the TD Group Loan Facility of approximately $193.8 million, together with substantially all of the proceeds received from the dividend payment from TransDigm Holdings, to:

• prepay the entire outstanding principal amount and all accrued and unpaid interest on TD Group’s senior unsecured promissory notes issued in connection with the Merger, with all such payments totaling approximately $262.7 million;

• make distributions to certain members of our management who participated in the Rollover Deferred Compensation Plan of their vested deferred compensation account balances (including Douglas Peacock, a director, who participated in the Rollover Deferred Compensation Plan as the former chief executive officer of TransDigm Inc. and TransDigm Holdings), with all such distributions totaling approximately $23.0 million; and

• make distributions to certain members of our management and one of our directors who participated in the Management Deferred Compensation Plan of their vested and a portion of their unvested deferred compensation account balances, with all such distributions totaling approximately $3.0 million (with approximately $1.8 million of such distributions being attributable to vested deferred compensation account balances and approximately $1.2 million being attributable to unvested deferred compensation account balances).

The approximately $6.2 million in aggregate bonuses paid by TransDigm Inc. and referred to above were allocated among our employees receiving such bonuses based on their respective holdings of rollover options and new management options.

In connection with the distributions under the Rollover Deferred Compensation Plan, the Board of Directors of TD Group approved the termination of the Rollover Deferred Compensation Plan, with such termination becoming effective on November 10, 2005. The Management Deferred Compensation Plan was terminated effective as of December 16, 2005 in connection with TD Group’s adoption of the New Management Deferred Compensation Plan, which is described in the following paragraph.

TD Group adopted the New Management Deferred Compensation Plan, in part, in connection with certain new requirements under Section 409A of the Internal Revenue Code of 1986, as amended. The New Management Deferred Compensation Plan is for the benefit of our employees who were granted new management options under our 2003 stock option plan. The New Management Deferred Compensation Plan is administered by the compensation committee of TD Group’s Board of Directors. The plan provides that a participant’s deferred compensation account is fully distributable upon the earlier of December 31, 2008 or a Change in Control (as defined in the plan). If a participant’s employment terminates by reason of death or disability, by the employee with good reason, or if a participant’s employment is terminated by the Company without Cause (as defined in the plan), a pro rata portion of the deferred compensation account, based on a fraction equal to the number of days elapsed between January 1, 2006 and the termination date over 1,096 (representing the number of days during the period from January 1, 2006 through December 31, 2008) will be distributed. If a participant’s employment is terminated for Cause or by the participant without good reason, the entire amount of the deferred compensation will be forfeited. Any amount distributable under the plan will be distributed no later than two and a half months following the end of the year in which the participant became entitled to the distribution. On December 16, 2005, the Board of Directors of TD Group approved contributions of $6.2 million, in the aggregate, to participant account balances under the plan.

Government Pricing Review

Certain parts sold by five of our divisions and subsidiaries to the Department of Defense through various buying agencies of the Defense Logistics Agency have been the subject of a pricing review by the Department of Defense Office of Inspector General. The pricing review examined whether the various buying offices within the Defense Logistics Agency had negotiated “fair and reasonable” prices for certain sole source spare parts purchased from those divisions and subsidiaries during fiscal years 2002 through 2004. On April 19, 2006, the Inspector General issued its final report dated February 23, 2006 and made public a redacted version thereof. The report recommends that Defense Logistics Agency contracting officers reevaluate their procedures for determining the reasonableness of pricing for sole source spare parts purchased from those divisions and subsidiaries and seek to develop Strategic Supplier Alliances with those divisions and subsidiaries.

We believe that the pricing review is part of a continuing effort by the Inspector General to monitor and evaluate prices paid to defense contractors for sole source spare parts. The report is consistent with reports issued with respect to sole source spare parts supplied by other companies, and, like those other reports, it advocates the negotiation of Strategic Supplier Alliances incorporating prices for parts based on cost, rather than based on prices of comparable commercial parts or other methods. We believe that our pricing of spare parts comports with the regulations applicable to contracts with agencies of the Federal government. Nonetheless, the report recommends that the Defense Logistics Agency request that the applicable divisions and subsidiaries of TransDigm Inc. voluntarily refund, in the aggregate, approximately $2.6 million for allegedly overpriced parts and negotiate Strategic Supplier Alliances incorporating cost-based prices for future Defense Logistics Agency purchases of sole source spare parts.

The Company’s position has been, and continues to be, that our pricing has been fair and reasonable and that there is no legal basis for the amount suggested as a refund by the Inspector General in its report. In response to the report, we offered reasons why we disagree with the Inspector General’s analysis and why computations related to a voluntary refund contained in the report failed to consider key data, such as actual historical sales. It cannot be determined at this time what the Defense Logistics Agency’s response to the report, and our response thereto, will be. If the Defense Logistics Agency requests a voluntary refund from any of our subsidiaries or divisions, we will consider such a request under the circumstances existing at that time.

Negotiations with the Defense Logistics Agency regarding Strategic Supplier Alliances have not yet commenced but will likely occur at a later date. As a result of those negotiations, it is possible that the divisions and subsidiaries subject to the pricing review will enter into Strategic Supplier Alliances with the Defense Logistics Agency. In connection with any Strategic Supplier Alliance, the Defense Logistics Agency may seek prices for parts based on cost or may seek volume discounts or other favorable pricing and/or the applicable division or subsidiary may agree to cost or pricing justification or appropriate discounts. It is also possible that the Department of Defense may seek alternative sources of supply for such parts.

The entry into Strategic Supplier Alliances or a decision by the Department of Defense to pursue alternative sources of supply for our sole source parts could reduce the amount of revenue we derive from, and the profitability of certain of our supply arrangements with, certain agencies and buying organizations of the U.S. Government. While management believes that the entry into Strategic Supplier Alliances with the Defense Logistics Agency will not have a material adverse effect on our financial condition, liquidity or capital resources, there is no means to determine the outcome of any future negotiations or discussions at this time.

EBITDA and EBITDA As Defined

The following table sets forth a reconciliation of net income to EBITDA and EBITDA As Defined.

	Thirteen Weeks Ended April 1, 2006		Thirteen Weeks Ended April 2, 2005		Twenty-Six Weeks Ended April 1, 2006			Twenty-Six Weeks Ended April 1, 2005

EBITDA As Defined (1)	$	48.1	$	40.5	$	90.5		$	75.4

(1) EBITDA represents earnings before interest, taxes, depreciation and amortization. EBITDA As Defined represents EBITDA, plus inventory purchase accounting adjustments, acquisition integration costs, non-cash compensation and deferred compensation charges, one-time special bonus payments and acquisition earnout costs.

We present EBITDA because we believe that it is a useful indicator of our operating performance. Our management believes that EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties to measure a company’s operating performance without regard to items such as interest and debt expense, income tax expense and depreciation and amortization, which may vary substantially from company to company depending upon, among other things, accounting methods, book value of assets, capital structure and the method by which assets are acquired. We also believe EBITDA is useful to our management and investors as a measure of comparative operating performance between time periods and among companies as it is reflective of changes in pricing decisions, cost controls and other factors that affect operating performance.

EBITDA As Defined represents EBITDA plus, as applicable for the relevant period, inventory purchase accounting adjustments, acquisition integration costs, non-cash compensation and deferred compensation costs, one-time special bonus payments made to certain members of our management and certain acquisition earnout costs. Our management uses EBITDA As Defined to review and assess our operating performance and management team in connection with our employee incentive programs, the preparation of our annual budget and financial projections. Our management also believes that EBITDA As Defined is useful to investors because the Amended and Restated Senior Credit Agreement requires compliance, on a pro forma basis, with certain financial ratios, including a leverage ratio, fixed charged coverage ratio and an interest coverage ratio. Leverage ratio is defined in the Amended and Restated Senior Credit Agreement, as of any date, as the ratio of the total indebtedness of TransDigm Inc. on a consolidated basis on such date to Consolidated EBITDA (as defined in the Amended and Restated Senior Credit Agreement) for the period of four consecutive fiscal quarters most recently ended on or prior to such date. Fixed charge coverage ratio is defined in the Amended and Restated Senior Credit Agreement as, for any period, the ratio of Consolidated EBITDA for such period

15

to consolidated fixed charges of TransDigm Inc. for such period. Interest coverage ratio is defined in the Amended and Restated Senior Credit Agreement as, for any period, the ratio of Consolidated EBITDA for such period to consolidated interest expense of TransDigm Inc. for such period. The Amended and Restated Senior Credit Agreement defines Consolidated EBITDA in a manner equal to how we define EBITDA As Defined. These financial covenants are material terms of the Amended and Restated Senior Credit Agreement as the failure to comply with such financial covenants could result in an event of default thereunder (and, in turn, an event of default under the Amended and Restated Senior Credit Agreement could result in an event of default under the Indenture governing the 8 ³/8% Senior Subordinated Notes and the TD Group Loan Facility).

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 EBITDA and EBITDA As Defined as an analytical tool has limitations and you should not consider either of them in isolation, or as a substitute for analysis of our results of operations as reported in accordance with accounting principles generally accepted in the United States of America, or 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, and our calculation of EBITDA and EBITDA As Defined may not be comparable to the calculation of similarly titled measures reported by other companies.

(2) Represents the portion of the purchase accounting adjustment to inventory pertaining to the Skurka and Fluid Regulators acquisitions in fiscal 2005 that was charged to cost of sales when the inventory was sold.

(3) Represents costs incurred to integrate the motor product line, Fluid Regulators and Avionic Instruments into the Company’s operations.

(4) Represents the expenses (income) recognized by the Company under a stock option plan and deferred compensation plans of TD Group. The amount reflected above for the twenty-six week period ended April 1, 2006 includes a reversal of previously recorded amounts charged to expense of $3.8 million resulting from the termination of two deferred compensation plans of TD Group. In addition, the amount reflected above for the thirteen and twenty-six week periods ended April 1, 2006 includes expenses recognized by the Company under a new deferred compensation plan of TD Group adopted December 2005.

(5) Represents the one-time special bonus paid to certain members of management based on their respective holdings of rollover options and new management options. In the Amendment to the Amended and

16

Restated Senior Credit Agreement entered into on November 10, 2005, our senior lenders agreed to exclude these one-time special bonus payments from the calculation of EBITDA As Defined.

(6) Represents the amount recognized for the potential earnout payment to Howard Skurka pursuant to the terms of the retention agreement entered into with him in connection with our acquisition of substantially all of the assets of Skurka in December 2004. In the Amendment to the Amended and Restated Senior Credit Agreement entered into on November 10, 2005, our senior lenders agreed to exclude earnout payments and deferred purchase price payments made in connection with certain permitted acquisitions from the calculation of EBITDA As Defined.

Critical Accounting Policies

Our consolidated financial statements have been prepared in accordance 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.

A summary of our significant accounting policies and estimates is included in the Registration Statement on Form S-1 for the year ended September 30, 2005. There has been no significant change to our critical accounting policies during the twenty-six week period ended April 1, 2006.

Changes in Results of Operations

Thirteen week period ended April 1, 2006 compared with the thirteen week period ended April 2, 2005.

• Net Sales. Net sales increased by $16.9 million, or 18.5%, to $108.3 million for the quarter ended April 1, 2006, from $91.4 million for the comparable quarter last year. Sales growth excluding acquisitions was $14.1 million and represented a 15.4% increase over the prior year. The organic sales growth was primarily due to: (i) an increase of $7.4 million of commercial aftermarket sales resulting from the continuing recovery in the commercial aerospace market as well as new business initiatives and (ii) an increase of $5.3 million of

17

commercial OEM sales primarily resulting from the increase in production rates for the Boeing Company and Airbus S.A.S and related OEM system suppliers as well as the business jet market. The remaining $2.8 million of the increase resulted from the acquisition of a motor product line in fiscal 2005.

• Cost of Sales. Cost of sales increased by $5.5 million, or 11.8%, to $51.8 million for the quarter ended April 1, 2006 from $46.3 million from the comparable quarter last year. Cost of sales as a percentage of sales decreased approximately 3 percentage points to 47.8% for the thirteen week period ended April 1, 2006 from 50.7% for the thirteen week period ended April 2, 2005. The increase in cost of sales was primarily due to increased volume associated with the higher net sales of $16.9 million discussed above. The decrease in cost of sales as a percentage of sales was primarily due to the favorable product mix (i.e., higher commercial aftermarket sales) and the absence in 2006 of a $0.9 million, or 1.0% of net sales, inventory purchase price accounting charge pertaining to the write-up of inventory associated with the acquisitions that occurred in fiscal 2005.

• Selling and Administrative Expenses. Selling and administrative expenses increased by $2.9 million, or 31.0%, to $12.4 million for the quarter ended April 1, 2006 from $9.5 million for the comparable quarter last year primarily due to non-recurring IPO costs of $1.7 million, or 1.5% of net sales, and higher costs to support the increase in sales discussed above. Selling and administrative expenses as a percentage of net sales increased to 11.5% for the quarter ended April 1, 2006 from 10.4% for the comparable quarter last year due primarily to the non-recurring IPO fees.

• Amortization of Intangibles. Amortization of intangibles decreased by $0.4 million to $1.5 million for the quarter ended April 1, 2006 from $1.9 million for the comparable quarter last year. The decrease was due to order backlog that was recorded in accounting for the acquisitions that was subsequently fully amortized during fiscal 2006.

• Interest Expense. Interest expense decreased slightly to $19.4 million for the quarter ended April 1, 2006 from $19.8 million for the comparable quarter last year.

• Income Taxes. Income tax expense as a percentage of income before income taxes increased to 38.5% for the quarter ended April 1, 2006 from 37.1% for the quarter ended April 2, 2005 primarily due to the reduction in the benefit related to foreign sales as a result of the change in the federal extraterritorial law which phases out the foreign sales deduction by 2007.

• Net Income. The Company earned $14.3 million for the second quarter of fiscal 2006 compared to $8.8 million for the second quarter of fiscal 2005, primarily as a result of the factors referred to above.

Twenty-six week period ended April 1, 2006 compared with the twenty-six week period ended April 2, 2005.

• Net Sales. Net sales increased by $36.7 million, or 21.4%, to $208.4 million for the twenty-six week period ended April 1, 2006, from $171.7 million for the comparable period last year. Sales growth excluding acquisitions was $24.1 million and represented a 14.1% increase over the prior year. The organic sales growth was primarily due to: (i) an increase of $14.2 million of commercial aftermarket sales resulting from the continuing recovery in the commercial aerospace market as well as new business initiatives; (ii) an increase of $12.2 million of commercial OEM sales primarily resulting from the increase in production rates for the Boeing Company and Airbus S.A.S and related OEM system suppliers as well as the business jet market and (iii) partially offsetting the increase in organic sales was a decrease in military sales. The remaining $12.6 million increase resulted from the acquisitions of Skurka, Fluid Regulators and the motor product line.

• Cost of Sales. Cost of sales increased by $15.6 million, or 17.9%, to $102.7 million for the twenty-six week period ended April 1, 2006 from $87.1 million from the comparable period last year. Cost of sales as a percentage of sales decreased approximately 1.5 percentage points to 49.3% for the twenty-six week period ended April 1, 2006 from 50.8% for the twenty-six week period ended April 2, 2005. The increase in cost of sales was primarily due to increased volume associated with the higher net sales of $36.7 million discussed above. The decrease in cost of sales as a percentage of sales was primarily due to the favorable product mix (i.e., higher commercial aftermarket sales) and the absence in 2006 of a $0.9 million, or 0.5% of net sales,

18

inventory purchase price accounting charge pertaining to the write-up of inventory associated with the acquisitions that occurred in fiscal 2005.

• Selling and Administrative Expenses. Selling and administrative expenses increased by $7.8 million to $25.5 million for the twenty-six week period ended April 1, 2006 from $17.7 million for the comparable period last year. The increase is due to (i) the one-time special bonus of $6.2 million, or 3.0% of net sales, paid to certain members of management, (ii) the higher net sales discussed above and (iii) non-recurring IPO costs of $2.4 million, or 1.1% of net sales. These increases were partially offset by (a) a reversal of previously recorded charges of $3.8 million, or 1.8% of net sales, resulting from the termination in fiscal 2006 of the Rollover Deferred Compensation Plan and the Management Deferred Compensation Plan and (b) the decrease of $1.5 million due to the lower compensation expense recorded under the New Management Deferred Compensation Plan.

Selling and administrative expenses as a percentage of net sales increased to 12.2% for the twenty-six week period ended April 1, 2006 from 10.3% for the comparable period last year primarily due to the factors described above.

• Amortization of Intangibles. Amortization of intangibles decreased by $0.4 million to $3.3 million for the twenty-six week period ended April 1, 2006 from $3.7 million for the comparable period last year. The decrease was due to order backlog that was recorded in accounting for the acquisitions made in fiscal 2005 that was subsequently fully amortized during fiscal 2006.

• Interest Expense. Interest expense decreased $0.2 million, or 0.4%, to $39.2 million for the twenty-six week period ended April 1, 2006 from $39.0 million for the comparable period last year.

• Income Taxes. Income tax as a percentage of income before income taxes increased to 38.4% for the quarter ended April 1, 2006 from 37.1% for the quarter ended April 2, 2005 primarily due to the reduction in the benefit related to foreign sales as a result of the change in the federal extraterritorial law which phases out the foreign sales deduction by 2007.

• Net Income. The Company earned $23.3 million for the twenty-six week period ended April 1, 2006 compared to $15.1 million for the same period last year, primarily as a result of the factors referred to above.

Backlog

As of April 1, 2006, the Company estimated its sales order backlog at $236.8 million compared to an estimated $200.8 million as of April 2, 2005. The increase in backlog of $36.0 million is primarily due to an increase among various products from both OEM and aftermarket customers, as well as an increase from the motor product line acquisition of $6.6 million. The majority of the purchase orders outstanding as of April 1, 2006 are scheduled for delivery within the next twelve months. Purchase orders may be subject to cancellation 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 1, 2006 may not necessarily represent the actual amount of shipments or sales for any future period.

Foreign Currency Exchange Rate Risk

We manufacture all of our products in the United States and sell our products in the United States, as well as in foreign countries. Substantially all of our foreign sales are transacted in U.S. dollars and, therefore, we have no material exposure to fluctuations in the rate of exchange between foreign currencies and the U.S. dollar. In addition, the amount of components or other raw materials or supplies that we purchase from foreign suppliers are not material, with substantially all such transactions being made in U.S. dollars. Accordingly, we have no material exposure to currency fluctuations in the rate of exchange between foreign currencies and the U.S. dollar arising from these transactions.

Inflation

Many of the Company’s raw materials and operating expenses are sensitive to the effects of inflation, which could result in changing operating costs. The effects of inflation on the Company’s business as a whole during the thirteen and twenty-six week periods ended April 1, 2006 and April 2, 2005 were not significant.

Liquidity and Capital Resources

Operating Activities. The Company used $61.1 million of cash from operating activities during the twenty-six weeks ended April 1, 2006 compared to $33.3 million provided during the twenty-six weeks ended April 2, 2005. The decrease of $94.4 million is primarily due to (i) additional interest payments of $74.3 million primarily relating to the payment of accrued interest of $62.7 million relating to the senior unsecured promissory notes in November 2005 and $4.8 million relating to the TD Group Loan Facility, (ii) distributions to participants in our deferred compensation plans totaling approximately $26.0 million in November 2005 (in connection with the distributions under the deferred compensation plans, our Board of Directors approved the termination of the plans during the first quarter of fiscal 2006) and (iii) the payment in November 2005 of a one-time special bonus to certain members of management of $6.2 million. These decreases are partially offset by a $12.0 million increase in operating cash flows as a result of an increase in net sales and other factors described in “Changes in Results of Operations” above.

Investing Activities. Cash used in investing activities decreased to $3.8 million during the twenty-six weeks ended April 1, 2006 compared to $58.2 million used during the twenty-six weeks ended April 2, 2005. The decrease in investing activities is primarily due to the absence of the acquisitions of Skurka and Fluid Regulators for $54.6 during fiscal 2005.

Financing Activities. Cash used in financing activities during the twenty-six weeks ended April 1, 2006 increased to $6.9 million compared to $3.0 million during the twenty-six weeks ended April 2, 2005, primarily due to the payment of approximately $200.0 million to prepay the entire outstanding principal balance of the senior unsecured promissory notes partially offset by the proceeds from the new TD Group Loan Facility, net of fees, of $193.8 million.

In connection with the closing of the TD Group Loan Facility, on November 10, 2005, TransDigm Inc. and TransDigm Holdings entered into the Amendment, which, among other things, authorized (i) the payment of the cash dividends and one-time special bonus payments described elsewhere in this Quarterly Report (see “Recent Developments – Dividend and Bonus Payments”) and (ii) TransDigm Inc. and TransDigm Holdings to make certain distributions to TD Group from time to time, so long as certain conditions are satisfied and the proceeds of such distributions to TD Group are used, directly or indirectly, by TD Group to pay interest in respect of the indebtedness outstanding under the TD Group Loan Facility. TransDigm Inc. and TransDigm Holdings intend to make such distributions, as permitted, on a quarterly basis.

The TD Group Loan Facility is unsecured and is not guaranteed by TransDigm Holdings or any of its direct or indirect subsidiaries, including TransDigm Inc. The TD Group Loan Facility matures in November 2011. The principal amount of the indebtedness outstanding under the TD Group Loan Facility is not amortized and, therefore, the entire balance of $200 million is payable upon maturity in November 2011, subject to certain required prepayment requirements.

The interest rates per annum applicable to the loans under the TD Group Loan Facility are equal to an adjusted LIBO rate for three-month interest periods plus an applicable margin percentage. The adjusted LIBO rate is determined by reference to settlement rates established for deposits in dollars in the London interbank market for three-month periods as adjusted for the maximum reserve percentages established by the Board of Governors of the United States Federal Reserve to which TD Group’s lenders are subject. Prior to the IPO, the applicable margin percentage was a percentage per annum equal to 5%. For any day on or after the IPO (the “Trigger Date”) until the day that is one year from the Trigger Date, the applicable margin percentage is a percentage per annum equal to 5.5%, and for any day on or after the date that is one year from the Trigger Date, the applicable margin percentage is a percentage per annum equal to 6%.

New Accounting Standards

During December 2004, the Financial Accounting Standards Board issued SFAS 123(R), which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. The Company anticipates adopting this pronouncement effective October 1, 2006. The Company anticipates that the adoption of this pronouncement will not have a material impact on its consolidated financial position or results of operations as SFAS 123(R) will be applied to option grants issued subsequent to December 20, 2005.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

At April 1, 2006, TD Group had borrowings under the TD Group Loan Facility and TransDigm Inc.’s Amended and Restated Senior Credit Facility of $488.4 million that were subject to interest rate risk. Borrowings under the TD Group Loan Facility bear interest at a rate equal to an adjusted LIBO rate for three-month interest periods plus an applicable margin percentage. Borrowings under the Amended and Restated Senior Credit Agreement bear interest, at TransDigm Inc.’s option, at a rate equal to either an alternate base rate or an adjusted LIBO rate for a one, two, three or six-month interest period chosen by the TransDigm Inc., 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 the TD Group Loan Facility and the Amended and Restated Senior Credit Agreement. The effect of a hypothetical one percentage point increase in interest rates would increase the annual interest costs under the TD Group Loan Facility and the Amended and Restated Senior Credit Agreement by approximately $4.9 million based on the amount of outstanding borrowings at April 1, 2006. The weighted average interest rate on the $488.4 million of total borrowings under the TD Group Loan Facility and the Amended and Restated Senior Credit Agreement on April 1, 2006 was 8.3%.

Because the interest rates on borrowings under the TD Group Loan Facility and the Amended and Restated Senior Credit Agreement vary with market conditions, the amount of outstanding borrowings under the TD Group Loan Facility and the Amended and Restated Senior Credit Agreement approximates the fair value of the indebtedness. The fair value of the $400 million aggregate principal amount of TransDigm Inc.’s 8 ³/8% Senior Subordinated Notes is exposed to the market risk of interest rate changes. The estimated fair value of such notes approximated $418 million at April 1, 2006 based upon quoted market rates.

Item 4. Controls and Procedures

As of April 1, 2006, 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 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 the 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.

Internal Control Over Financial Reporting

There have been no changes in TD Group’s internal control over financial reporting that occurred during the twenty-six week period ending April 1, 2006 that have materially affected, or are reasonably likely to materially affect, TD Group’s internal control over financial reporting.

Sarbanes-Oxley Act – Section 404 Compliance

Section 404 of the Sarbanes-Oxley Act requires the Company’s management to report on, and its independent auditors to attest to, the Company’s internal control over financial reporting as of September 30, 2007. The Company is actively continuing its compliance efforts and utilizing outside assistance of documenting, testing and evaluating the effectiveness of its internal control over financial reporting in order to be in full compliance with all requirements of Section 404 as of September 30, 2007.
