Exhibit 99.1

TransDigm To Acquire Aviation Technologies Inc. From Odyssey Investment Partners

CLEVELAND, January 9, 2007 /PRNewswire-FirstCall/ — TransDigm Group Incorporated (NYSE: TDG) announced today a definitive agreement to purchase Aviation Technologies Inc. (“ATI”), a privately-owned supplier of innovative aerospace products, for a total enterprise value of approximately $430 million in cash. TransDigm expects to finance the acquisition primarily through a combination of senior and subordinated debt.

ATI, which is based in Seattle, WA, consists of two primary operating units that service the commercial and military aerospace markets – Avtech and ADS/Transicoil. Avtech is a leading supplier of flight deck and passenger audio systems; cabin lighting and power control products and related components. ADS/Transicoil is a leading supplier of displays, clocks, brushless motors and related components and instruments. About 95% of ATI’s revenue is generated from the global aerospace industry, with approximately 80% of such revenues coming from the commercial market and approximately 20% of such revenue coming from the military market. ATI employs approximately 600 people in its Seattle (WA), Bellevue (WA), Collegeville (PA) and Malaysian operations.

“This is the first sizable acquisition opportunity that we have seen in several years that meets our stringent strategic, operational and value-creation criteria,” stated W. Nicholas Howley, TransDigm’s Chairman and Chief Executive Officer. ”ATI fits well with our consistent focus on proprietary aerospace components with broad platform positions and significant aftermarket content. Approximately 90% of ATI’s revenue comes from proprietary products and about 50% of ATI’s revenue is related to the aftermarket. Additionally, this acquisition expands our existing positions in aerospace motors and electrical power applications and also opens up a new growth platform in flight deck and cabin electronics products.”

For the calendar year ending December 31, 2006, ATI is expected to have approximately $105 million in revenues and approximately $35 million of EBITDA (earnings before interest, taxes, depreciation and amortization). The 2006 EBITDA is expected to include approximately $3 million of program development expenses for products that ATI will be providing on the Boeing 787, $3 million of ATI corporate overhead, and $1 million of one time relocation/severance charges.

“These are well run businesses,” continued Mr. Howley, “However, consistent with our past acquisition history, we expect to see margin improvements as we integrate the ATI businesses into our culture and management processes. We expect to realize cost savings relatively quickly in ATI’s corporate overhead, and then to more gradually improve the margins as Boeing 787 development costs ramp down, our restructuring activities are concluded, and we implement TransDigm’s value drivers throughout the organization.

Excluding purchase price accounting adjustments, we anticipate this acquisition will be slightly accretive over the first twelve months of ownership and increasingly so thereafter.”

The acquisition, which is expected to close in the next 60 days, is subject to regulatory approvals and customary closing conditions. The transaction will be accounted for under purchase accounting rules.
