TRANSDIGM GROUP INCORPORATED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

THIRTEEN AND TWENTY-SIX WEEK PERIODS ENDED MARCH 28, 2009 AND MARCH 29, 2008

(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, AeroControlex Group, Inc., MarathonNorco Aerospace, Inc., Adams Rite Aerospace, Inc., Champion Aerospace LLC, Avionic Instruments LLC, Skurka Aerospace Inc., CDA InterCorp LLC, Avtech Corporation, Transicoil LLC, Transicoil (Malaysia) Sendirian Berhad, Bruce Aerospace, Inc., CEF Industries, Inc. and Aircraft Parts Corporation (collectively, with TD Group, 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 mechanical/electromechanical actuators and controls, ignition systems and components, gear pumps, specialized valves, engineered connectors, power conditioning devices, specialized fluorescent lighting and AC/DC electric motors, aircraft audio systems, engineered latches and cockpit security devices, lavatory hardware and components, hold open rods and locking devices, specialized cockpit displays, elastomers, NiCad batteries/chargers, and starter generators and related components.

Separate Financial Statements – Separate financial statements of TransDigm Inc. are not presented since TransDigm Inc.’s 7³/4% 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 since 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, 2008 included in TD Group’s Form 10-K dated November 25, 2008. The September 30, 2008 condensed consolidated balance sheet was derived from the TD Group’s audited financial statements. The results of operations for the twenty-six week period ended March 28, 2009 are not necessarily indicative of the results to be expected for the full year.

3.	NEW ACCOUNTING STANDARDS

In February 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115” (“SFAS 159”). SFAS 159 provides companies with an option to report selected financial assets and liabilities at fair value. SFAS 159’s objective is to reduce both complexity in accounting for financial instruments and the volatility in earnings caused by measuring related assets and liabilities differently. The adoption of SFAS 159 as of October 1, 2008 did not have a material impact on the Company’s consolidated financial position or results of operations.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS 157”), which is effective for fiscal years beginning after November 15, 2007 and for interim periods within those years. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands the related disclosure requirements. In October 2008, the FASB issued FASB Staff Position FAS 157-3, “Determining the Fair Value of a Financial Asset When the Market for That Asset Is Not Active” (“FSP 157-3”), which clarifies the application of SFAS 157 when the market for a financial asset is not active and provides an example to illustrate key considerations in determining the fair value of a financial asset when the market for that financial asset is not active. FSP 157-3 became effective immediately upon adoption of SFAS 157. SFAS 157 was adopted as of October 1, 2008 for all financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). The effective provisions of SFAS 157 are included in Note 10, “Fair Value of Financial Instruments.” The adoption of SFAS 157 did not have a material impact on the Company’s consolidated financial position or results of operations.

-5-

In February 2008, the FASB issued FASB Staff Position No. FAS 157-2, “Effective Date of FASB Statement No. 157” (“FSP 157-2”), which allows for the deferral of the adoption date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or presented at fair value in the financial statements on a recurring basis to fiscal years beginning after November 15, 2008. The adoption of SFAS 157 for those assets and liabilities within the scope of FSP 157-2 is not expected to have a material impact on our financial position, results of operations or cash flows.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”). SFAS 161 requires disclosures of how and why an entity uses derivative instruments, how derivative instruments and related hedged items are accounted for and how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. SFAS 161 is effective for interim periods beginning after November 15, 2008 and fiscal years that include those interim periods. The adoption of SFAS 161 as of December 28, 2008 did not have a material impact on the Company’s consolidated financial position or results of operations. See Note 10.

4.	ACQUISITIONS

APC – On December 16, 2008, TransDigm Inc. acquired all of the outstanding capital stock of Aircraft Parts Corporation (“APC”) for approximately $67.5 million in cash, subject to adjustment based on the level of working capital as of the closing date of the acquisition. APC is a designer and manufacturer of starter generators, generator control units and related components for turbine engines, all of which fit well with TransDigm’s overall business direction. The Company expects that the $48.3 million of estimated goodwill recognized for the acquisition will not be deductible for tax purposes.

Unison Product Line – On September 26, 2008, TransDigm Inc., through its wholly-owned Champion Aerospace, LLC subsidiary, acquired certain assets related to the magneto and harness product line business of Unison Industries, LLC (“Unison product line”) for approximately $68.3 million in cash, net of a purchase price adjustment of $1.1 million received in November 2008. The acquired product line includes the highly engineered SLICK^TM magnetos, harnesses and components, which are used on substantially all of the world’s general aviation piston aircraft. These products fit well with Champion’s existing product offerings and TransDigm’s overall business direction. The Company expects that the $58.5 million of estimated goodwill recognized for the acquisition will be deductible for tax purposes.

CEF – On May 7, 2008, TransDigm Inc. acquired all of the outstanding capital stock of CEF Industries, Inc. (“CEF”) for approximately $84.4 million in cash, net of a purchase price adjustment of $0.5 million received in January 2009. CEF is a designer and manufacturer of specialized and highly engineered actuators, compressors, pumps and related components for the aerospace market, all of which fit well with TransDigm’s overall business direction. The Company expects that the $52.2 million of estimated goodwill recognized for the acquisition will not be deductible for tax purposes.

The Company accounted for the acquisitions of APC, the Unison product line, and CEF (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. The Company is in the process of obtaining third-party valuations of certain tangible and intangible assets of APC and the Unison product line; thus, the values attributed to acquired assets in the consolidated financial statements are subject to adjustment. Pro forma net sales and results of operations for the Acquisitions, had they occurred at the beginning of the twenty-six week periods ended March 28, 2009 and March 29, 2008, respectively, 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 primarily by the recurring aftermarket consumption over the life of a particular aircraft, which is estimated to be approximately 30 years.

5.	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. Approximately 9% of the inventory was valued under the LIFO method at March 28, 2009.

The Company provides limited warranties in connection with the sale of its products. The warranty period for products sold varies among the Company’s operations, ranging generally from 90 days to six years. A provision for the estimated cost to repair or replace the products is recorded at the time of sale and periodically adjusted to reflect actual experience.

The following table presents a reconciliation of changes in the product warranty liability for the periods indicated below (in thousands):


	Twenty-Six Week Periods Ended
	March 28, 2009			March 29, 2008

8.	INCOME TAXES

At the end of each reporting period, the Company makes an estimate of its annual effective income tax rate. The estimate used in the year-to-date period may change in subsequent periods. The Company recorded an income tax provision of $22.8 million in the thirteen week period ended March 28, 2009 compared to $16.6 million in the prior year period. The effective tax rate for the thirteen week period ended March 28, 2009 was 36.2% compared to 34.0% for the comparable period in the prior year. The higher effective tax rate was primarily due to the favorable resolution at March 29, 2008, of a prior year state tax refund claim of $0.9 million that reduced the effective rate for that quarter by approximately two percentage points.

-8-

The Company recorded an income tax provision of $44.1 million in the twenty-six week period ended March 28, 2009 compared to $32.0 million in the prior year period. The effective tax rate was 35.6% for the twenty-six weeks ended March 28, 2009 and was comparable to the 35.1% for the twenty-six week period ended March 29, 2008.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction as well as in various state jurisdictions. As of March 28, 2009, the Company is subject to a U.S. Federal income tax examination for fiscal years 2007 and 2008. In addition, the Company is subject to state and local income tax examinations for fiscal years 2004 through 2008.

At March 28, 2009, the Company had $3.1 million in unrecognized tax benefits, the recognition of which would have an effect of approximately $2.1 million on the effective tax rate. At September 30, 2008, the Company had $2.8 million in unrecognized tax benefits, the recognition of which would have an effect of approximately $1.9 million on the effective tax rate. 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.

9.	EARNINGS PER SHARE CALCULATION

Basic earnings per share is determined using the weighted-average number of common shares outstanding during the period. Diluted earnings per share includes the additional effect of potentially dilutive securities, which comprise stock options outstanding during the period. The dilutive effect of stock options is calculated using the treasury stock method.

The following table sets forth the computation of basic and diluted earnings per share:


(in thousands, except per share data)	Thirteen Week Periods Ended				Twenty-Six Week Periods Ended
	March 28, 2009		March 29, 2008		March 28, 2009		March 29, 2008
Basic Earnings Per Share Computation:
Net income	$	40,305	$	32,170	$	79,903	$	59,138

Weighted-average shares outstanding		48,261		47,605		48,429		47,415

Basic earnings per share	$	0.84	$	0.68	$	1.65	$	1.25


Diluted Earnings Per Share Computation:
Net income	$	40,305	$	32,170	$	79,903	$	59,138

Weighted-average shares outstanding		48,261		47,605		48,429		47,415
Effect of dilutive options outstanding		1,956		2,432		1,944		2,537

Total weighted-average shares outstanding		50,217		50,037		50,373		49,952

Diluted earnings per share	$	0.80	$	0.64	$	1.59	$	1.18

Stock options totaling 0.3 million outstanding at March 28, 2009 were excluded from the diluted earnings per share computations for the thirteen and twenty-six week periods ended March 28, 2009 due to the anit-dilutive effect of such options. The stock options excluded from the diluted earnings per share calculation for thirteen and twenty-six week periods ended March 29, 2008 were immaterial.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company has various financial instruments, including cash and cash equivalents, accounts receivable and payable, accrued liabilities, interest rate swaps and long-term debt. SFAS 157 (See Note 3) establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. 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.

The carrying value of the Company’s cash and cash equivalents, accounts receivable and payable, and accrued liabilities approximates their fair value due to the short-term maturities of these assets and liabilities. The estimated fair value of the Company’s term loans approximated $706 million at March 28, 2009 based on information provided by the agent under the Company’s Senior Secured Credit Facility. The estimated fair value of the Company’s 7³/4% Senior Subordinated Notes approximated $541 million at March 28, 2009 based upon quoted market prices.

Interest rate swap agreements are entered into to manage interest rate risk associated with floating-rate borrowings under our Senior Secured Credit Facility of $780 million. The interest rate swap agreements utilized by the Company effectively modify the Company’s exposure to interest rate risk by converting a portion of the Company’s floating-rate debt to a fixed rate basis through the expiration dates of the agreements, thereby reducing the impact of interest rate changes on future interest expense. These agreements involve the receipt of floating rate amounts in exchange for fixed rate interest payments over the life of the agreements without an exchange of the underlying principal amounts. These derivative instruments qualify as effective cash flow hedges under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities.” Accordingly, changes in the fair values of the interest rate swaps are recorded as other comprehensive income. At March 28, 2009, we had agreements in place to swap variable interest rates on our Senior Secured Credit Facility for fixed interest rates for the notional amount of $150 million through June 23, 2009 and for the notional amount of $300 million through March 23, 2011.

The following table provides the liabilities carried at fair value measured on a recurring basis as of March 28, 2009 (in thousands):


			Fair Value Measurements Using Inputs Considered as
	Fair Value at March 28, 2009		Level 1		Level 2		Level 3
Interest Rate Swaps ⁽¹⁾	$	10,155	$	—	$	10,155	$	—
(1) Included in Accrued liabilities and Other non-current liabilities on the Condensed Consolidated Balance Sheets.

Interest rate swaps are 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. They are classified within Level 2 of the valuation hierarchy.

11.

COMPREHENSIVE INCOME

Comprehensive income, which includes adjustments for changes in the fair values of the interest rate swap agreements on a net of tax basis, was approximately $73.0 million and $53.3 million for the twenty-six week periods ended March 28, 2009 and March 29, 2008, respectively.

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: a decrease in flight hours and our customers’ profitability, both of which are affected by general economic conditions; future terrorist attacks; our substantial indebtedness; 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; the pricing review by the Department of Defense Office of Inspector General to which certain of our divisions and subsidiaries have been subject; failure to complete or successfully integrate acquisitions; future sales of our common stock in the public market caused by the substantial amount of stock held by our affiliates; 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 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/electromechanical actuators and controls, ignition systems and components, gear pumps, specialized valves, engineered connectors, power conditioning devices, specialized fluorescent lighting and AC/DC electric motors, aircraft audio systems, engineered latches and cockpit security devices, lavatory hardware and components, hold open rods and locking devices, specialized cockpit displays, elastomers, NiCad batteries/chargers, and starter generators and related components. 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 2009, we generated net sales of $193.0 million and net income of $40.3 million. EBITDA As Defined was $94.4 million, or 48.9% of net sales. See below for certain information regarding EBITDA and EBITDA As Defined, including a reconciliation of EBITDA and EBITDA As Defined to net income.

Certain Acquisitions

APC Acquisition

On December 16, 2008, TransDigm Inc. acquired all of the outstanding capital stock of Aircraft Parts Corporation (“APC”) for approximately $67.4 million in cash, subject to adjustment based on the level of working capital as of the closing date of the acquisition. APC is a designer and manufacturer of starter generators, generator control units and related components for turbine engines, all of which fit well with TransDigm’s overall business direction.

Unison Product Line Acquisition

On September 26, 2008, TransDigm Inc., through its wholly-owned Champion Aerospace, LLC subsidiary, acquired certain assets related to the magneto and harness product line business of Unison Industries, LLC (“Unison product line”) for approximately $68.3 million in cash, net of purchase price adjustment of $1.1 million received in November 2008. The acquired product line includes the highly engineered SLICK^TM magnetos, harnesses and components, which are used on substantially all of the world’s general aviation piston aircraft. These products fit well with Champion’s existing product offerings and TransDigm’s overall business direction.

CEF Acquisition

On May 7, 2008, TransDigm Inc. acquired all of the outstanding capital stock of CEF Industries, Inc. (“CEF”) for approximately $84.4 million in cash, net of a purchase price adjustment of $0.5 million received in January 2009. CEF is a designer and manufacturer of specialized and highly engineered actuators, pumps and related components for the aerospace market, all of which fit well with TransDigm’s overall business direction.

EBITDA and EBITDA As Defined

EBITDA represents earnings before interest, taxes, depreciation and amortization. EBITDA As Defined represents EBITDA plus, as applicable for the relevant period, inventory purchase accounting adjustments, acquisition integration costs and non-cash compensation and deferred compensation charges. EBITDA and EBITDA As Defined are non-GAAP financial measures which the management of TransDigm Group believes are useful indicators for evaluating operating performance and liquidity.

TransDigm Group management believes that EBITDA and EBITDA As Defined are useful to investors because they are frequently used by securities analysts, investors and other interested parties to measure operating performance among companies with different capital structures, effective tax rates and tax attributes, capitalized asset values and employee compensation structures, all of which can vary substantially from company to company depending upon, among other things, accounting methods, book value of assets and the method by which assets are acquired. These measures are useful to evaluate our Company between time periods without regard to items such as interest expense, income tax expense and depreciation and amortization. We also believe EBITDA is useful to investors as a measure of comparative operating performance among companies and between time periods as it is reflective of changes in pricing decisions, cost controls and other factors that affect operating performance.

TransDigm Group management believes that EBITDA and EBITDA As Defined are useful as indicators of liquidity because analysts, 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 first lien leverage ratio, which is measured based on our Consolidated EBITDA. Our senior secured credit facility defines Consolidated EBITDA in the same manner as we define EBITDA As Defined. 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 thereunder (and, in turn, an event of default under our senior secured credit facility could result in an event of default under the indenture governing our 7³/4% senior subordinated notes).

In addition to the above, TransDigm Group’s management uses EBITDA As Defined to review and assess its operating performance and management team in connection with employee incentive programs and the preparation of its annual budget and financial projections. Moreover, TransDigm Group’s management uses EBITDA As Defined to evaluate acquisitions and as a liquidity measure.

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 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.

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.

SFAS No. 142, “Goodwill and Other Intangibles”, 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. Certain of the acquisitions were or are being integrated into an existing operating subsidiary, and therefore any related goodwill is combined with goodwill of the operating subsidiary.

A summary of our significant accounting policies and estimates is included in the Annual Report on Form 10-K for the year ended September 30, 2008. There has been no significant change to our critical accounting policies during the twenty-six week period ended March 28, 2009.

Changes in Results of Operations

Thirteen week period ended March 28, 2009 compared with the thirteen week period ended March 29, 2008.

•

Net Sales. Net sales increased by $17.8 million, or 10.1%, to $193.0 million for the quarter ended March 28, 2009, from $175.3 million for the comparable quarter last year. The increase in sales was primarily a result of the acquisitions of CEF and the Unison product line during fiscal 2008 and APC in fiscal 2009 of $20.3 million.

Sales excluding acquisitions decreased by $2.5 million and represented a 1.5% decrease from the prior year. The decline in organic sales was primarily due to (i) a decrease of $6.3 million of commercial OEM sales resulting primarily from a reduction in sales to The Boeing Company due to a decrease in production from Boeing’s employee strike and decline in production rates in the business jet market, and (ii) a decrease of $1.4 million in commercial aftermarket sales. Partially offsetting the decline in organic commercial sales was an increase of $6.4 million in defense sales primarily due to increased demand for aftermarket spare parts and repairs across most of our product lines.

•

Cost of Sales. Cost of sales increased by $2.9 million, or 3.5%, to $84.2 million for the quarter ended March 28, 2009 from $81.4 million for the comparable quarter last year primarily due to the increase volume associated with the higher net sales of $17.8 million discussed above. Cost of sales as a percentage of sales decreased to 43.6% for the thirteen week period ended March 28, 2009 from 46.4% for the thirteen week period ended March 29, 2008. Cost of sales as a percentage of net sales decreased by almost three percentage points due to the strength of our proprietary products, productivity improvements from continued cost reduction initiatives and favorable product mix partially offset by the dilutive impact from recent acquisitions.

•

Selling and Administrative Expenses. Selling and administrative expenses increased by $2.0 million to $20.4 million, or 10.6% of sales, for the quarter ended March 28, 2009 from $18.4 million, or 10.5% of sales, for the comparable quarter last year primarily due to the higher sales discussed above.

•

Amortization of Intangibles. Amortization of intangibles increased to $3.6 million for the quarter ended March 28, 2009 from $2.8 million for the comparable quarter last year. The net increase of $0.8 million was primarily due to amortization expense related to the additional identifiable intangible assets recognized in connection with acquisitions during the last twelve months partially offset by the order backlog becoming fully amortized in fiscal 2008 relating to prior acquisitions.

-22-

•

Interest Expense-net. Interest expense decreased $2.4 million, or 9.9%, to $21.6 million for the quarter ended March 28, 2009 from $24.0 million for the comparable quarter last year as a result of lower interest rates and partially offset by a decrease in interest income of $1.5 million. The Company’s weighted average level of outstanding borrowings was approximately $1.36 billion for both the quarter ended March 28, 2009 and the comparable quarter last year. The average interest rate decreased to 6.1% for the quarter ended March 28, 2009 from 7.3% during the comparable quarter last year.

•

Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 36.2% for the quarter ended March 28, 2009 compared to 34.0% for the quarter ended March 29, 2008. The prior year lower effective tax rate was primarily due to the favorable resolution of a state tax refund claim of $0.9 million that reduced the effective tax rate for the quarter ended March 29, 2008 by approximately two percentage points.

•

Net Income. Net income increased $8.1 million, or 25.3%, to $40.3 million for the second quarter of fiscal 2009 compared to $32.2 million for the second quarter of fiscal 2008, primarily as a result of the factors referred to above.

Twenty-six week period ended March 28, 2009 compared with the twenty-six week period ended March 29, 2008.

•

Net Sales. Net sales increased by $35.9 million, or 10.6%, to $374.3 million for the twenty-six week period ended March 28, 2009, from $338.4 million for the comparable period last year. The increase in sales was primarily a result of the acquisitions of CEF and the Unison product line in fiscal 2008 and APC in fiscal 2009 of $34.0 million.

Sales growth excluding acquisitions was $1.9 million and represented a 0.6% increase over the prior year. The organic sales growth was primarily due to an increase of $13.7 million in defense sales resulting from an increase in demand for aftermarket spare parts across most of our product lines. The increase in defense sales was partially offset by a decrease of $6.1 million of commercial aftermarket sales due to the impact of the global economic downturn resulting in a decline in worldwide airline traffic and a decrease of $4.1 million of commercial OEM sales primarily resulting from a reduction in sales to The Boeing Company due to a decrease in production from Boeing’s employee strike.

•

Cost of Sales. Cost of sales increased by $4.8 million, or 3.1%, to $161.2 million for the twenty-six week period ended March 28, 2009 from $156.4 million for the comparable period last year. Cost of sales as a percentage of sales decreased to 43.1% for the twenty-six week period ended March 28, 2009 from 46.2% for the twenty-six week period ended March 29, 2008. The absolute dollar increase in cost of sales was primarily due to increased volume associated with the higher net sales of $35.9 million discussed above.

The decrease in cost of sales as a percentage of sales of slightly more than three percentage points was due to the strength of our proprietary products, productivity improvements from continued cost reduction initiatives and favorable product mix partially offset by the dilutive impact from recent acquisitions.

•

Selling and Administrative Expenses. Selling and administrative expenses increased by $2.4 million, or 6.5%, to $38.6 million, or 10.3% of sales, for the twenty-six week period ended March 28, 2009 from $36.2 million, or 10.7% of sales, for the comparable period last year. This increase was primarily due to the higher sales discussed above partially offset by a decrease in research and development expenses of $1.6 million, or 0.6% of net sales, primarily relating to development costs for the Boeing 787 program.

•

Amortization of Intangibles. Amortization of intangibles increased to $6.8 million for the twenty-six week period ended March 28, 2009 from $6.1 million for the comparable period last year. The net increase of $0.7 million was primarily due to amortization expense related to the additional identifiable intangible assets recognized in connection with acquisitions during the last twelve months partially offset by the order backlog becoming fully amortized in fiscal 2008 relating to prior acquisitions.

•

Interest Expense-net. Interest expense decreased $4.9 million, or 10.1%, to $43.6 million for the twenty-six week period ended March 28, 2009 from $48.5 million for the comparable period last year primarily the result of lower interest rates and partially offset by a decrease in interest income of $2.5 million. The Company’s weighted average level of outstanding borrowings was approximately $1.36 billion for both the twenty-six week period ended March 28, 2009 and March 29, 2008, respectively. The average interest rate decreased to 6.2% for the twenty-six week period ended March 28, 2009 from 7.4% during the comparable period last year.

-23-

•

Income Taxes. Income tax expense as a percentage of income before income taxes was 35.6% for the twenty-six weeks ended March 28, 2009 and was comparable to the 35.1% for the twenty-six week period ended March 29, 2008.

•

Net Income. Net income increased $20.8 million, or 35.1%, to $79.9 million for the twenty-six week period ended March 28, 2009 compared to net income of $59.1 million for the twenty-six week period ended March 29, 2008, primarily as a result of the factors referred to above.

Backlog

As of March 28, 2009, the Company estimated its sales order backlog at $407.2 million compared to an estimated $378.3 million as of March 29, 2008. This increase in backlog of $28.9 million is mainly due to the purchase orders acquired in connection with the acquisitions of CEF, the Unison product line and APC, discussed above, totaling approximately $41.7 million as of March 28, 2009. The majority of the purchase orders outstanding as of March 28, 2009 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 March 28, 2009 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 through our wholly owned Malaysian subsidiary. We 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 as a result of foreign sales. In addition, the amount of components or other raw materials or supplies that we purchase from foreign suppliers, including our Malaysian manufacturing subsidiary, 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.

Sales to foreign customers are subject to numerous additional risks, including the impact of foreign government regulations, political uncertainties and differences in business practices. 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’ 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 $79.5 million of cash from operating activities during the twenty-six week period ended March 28, 2009 compared to $78.2 million during the twenty-six week period ended March 29, 2008.

Investing Activities. Cash used in investing activities was $72.3 million during twenty-six week period ended March 28, 2009 consisting primarily of the acquisition of APC and capital expenditures of $5.8 million. Cash used in investing activities was $4.2 million during twenty-six week period ended March 29, 2008 consisting of capital expenditures.

Financing Activities. Cash used in financing activities during the twenty-six week period ended March 28, 2009 was $11.7 million compared to cash provided by financing activities of $14.1 million during the twenty-six week period ended March 29, 2008. Cash used in financing activities during the twenty-six week period ended March 28, 2009 related to the purchase of treasury stock of $15.2 million partially offset by the benefit from the exercise of stock options of $3.5 million. Cash provided by financing activities during the twenty-six week period ended March 29, 2008 related to the exercise of stock options of $14.1 million.

Description of Current Senior Secured Credit Facility and Indenture

The senior secured credit facility (“Senior Secured Credit Facility”) consists of a $780 million term loan facility, which is fully drawn, and a $200 million revolving loan facility. At March 28, 2009, $198.5 million of the revolving credit facility was available.

The term loan facility will mature in June 2013 and will not be subject to interim scheduled amortization, but will be subject to certain prepayment requirements. Under the amended terms of the Senior Secured Credit Facility, commencing 90 days after the end of fiscal 2008 and each fiscal year thereafter, TransDigm Inc. is required to prepay outstanding term loans in a principal amount equal to 50% of Excess Cash Flow (as defined in the Senior Secured Credit Facility) if our Consolidated Leverage Ratio (as hereinafter defined) at the end of the applicable fiscal year exceeds 5.00 to 1.00 and equal to 25% of Excess Cash Flow if our Consolidated Leverage Ratio at the end of the applicable fiscal year is less than 5.00 to 1.00, but greater than 4.50 to 1.00. No payment is required if the Consolidated Leverage Ratio as of the end of the applicable fiscal year is equal to or less than 4.50 to 1.00 or if the term loans achieve certain minimum credit ratings at the end of such fiscal year. “Excess Cash Flow” is a negotiated definition generally designed to capture the cash that was generated by our business in excess of cash used in the business. “Consolidated Leverage Ratio” means the ratio of consolidated total indebtedness to the aggregate amount of EBITDA As Defined, calculated on a pro forma basis. TransDigm’s Consolidated Leverage Ratio was approximately 3.9 to 1.00 at September 30, 2008, thus the Company was not obligated to make a prepayment of the term loans based upon the Excess Cash Flow provision.

TransDigm Inc. entered into a three year interest rate swap in June 2006 with Credit Suisse for an initial notional amount of $187 million at a fixed rate of 7.6%. The notional amount decreased to $150 million on September 23, 2008. TransDigm Inc. entered into an additional three year interest rate swap in January 2008 with Credit Suisse for a notional amount of $300 million at a fixed rate of 5.0%.

Long-term financing arrangements also include $575 million aggregate principal amount of 7³/4% senior subordinated notes (“7³/ 4% Senior Subordinated Notes”) issued by TransDigm Inc. Such notes do not require principal payments prior to their maturity in July 2014.

Stock Repurchase

In October 2008, we announced a program permitting us to repurchase a portion of our outstanding shares not to exceed $50 million in the aggregate. From October 2008 to March 2009, we have repurchased a total of 494,100 shares at an aggregate cost of $15.2 million.

New Accounting Standards

-25-

SFAS 159’s objective is to reduce both complexity in accounting for financial instruments and the volatility in earnings caused by measuring related assets and liabilities differently. The adoption of SFAS 159 as of October 1, 2008 did not have a material impact on the Company’s consolidated financial position or results of operations.

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 March 28, 2009, we had borrowings under our Senior Secured Credit Facility of $780 million 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 Senior Secured Credit Facility by approximately $7.8 million based on the amount of outstanding borrowings at March 28, 2009. The weighted average interest rate on the $780 million of borrowings under our Senior Secured Credit Facility on March 28, 2009 was 3.23%.

At March 28, 2009, we had an agreement in place to swap variable interest rates on our Senior Secured Credit Facility for fixed interest rates through June 23, 2009 for the notional amount of $150 million. The fair value of the interest rate swap agreement is adjusted at each balance sheet date, with a corresponding adjustment to other comprehensive income. At March 28, 2009, the fair value of the interest rate swap agreement was a liability of $1.6 million.

At March 28, 2009, we had an agreement in place to swap variable interest rates on our Senior Secured Credit Facility for fixed interest rates through March 23, 2011 for the notional amount of $300 million. The fair value of the interest rate swap agreement is adjusted at each balance sheet date, with a corresponding adjustment to other comprehensive income. At March 28, 2009, the fair value of the interest rate swap agreement was a liability of $8.5 million.

The fair value of the $780 million aggregate principal amount of borrowings under the Senior Secured Credit Facility is exposed to the market risk of interest rates. The estimated fair value of such term loan approximated $706 million at March 28, 2009 based upon

-26-

information provided to the Company from its agent under the credit facility. The fair value of the $575 million aggregate principal amount of our 7³/4% Senior Subordinated Notes is exposed to the market risk of interest rate changes. The estimated fair value of such notes approximated $541 million at March 28, 2009 based upon quoted market rates.

ITEM 4.

CONTROLS AND PROCEDURES

As of March 28, 2009, 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 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

There have been no changes in TD Group’s internal control over financial reporting that occurred during the thirteen week period ending March 28, 2009 that have materially affected, or are reasonably likely to materially affect, TD Group’s internal control over financial reporting.
