NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

THIRTEEN WEEKS ENDED DECEMBER 31, 2005 AND JANUARY 1, 2005

(UNAUDITED)



|1. | DESCRIPTION OF THE BUSINESS AND MERGER
|-- | --------------------------------------



Description of the BusinessTransDigm Holding Company (Holdings), 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 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.



MergerOn July 22, 2003, an entity formed by Warburg Pincus Private Equity VIII, L.P. (Warburg Pincus) merged with and into Holdings, with Holdings continuing as the surviving corporation
and as a wholly-owned subsidiary of a newly formed corporation controlled by Warburg Pincus, TD Holding Corporation (the Merger). On January 19, 2006, TD Holding Corporation changed its legal name to TransDigm Group Incorporated
(TD Group).



Separate Financial
StatementsSeparate financial statements of TransDigm Inc. are not presented since the 83/8% Senior Subordinated Notes due July 2011 issued by TransDigm Inc. are fully and unconditionally guaranteed on a senior subordinated basis by Holdings and all existing domestic subsidiaries of TransDigm Inc. and since Holdings 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 included in the Annual Report on Form 10-K for the year ended September 30, 2005 filed by Holdings and TransDigm Inc. The September 30, 2005 condensed consolidated
balance sheet was derived from Holdings audited financial statements. The results of operations for the thirteen weeks ended December 31, 2005 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 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 On June 30, 2005, TransDigm, 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 company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 in accounting for the acquisition will be deductible for income tax purposes.



Fluid Regulators  On January 28, 2005, TransDigm Inc. 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 Regulators 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 of goodwill recognized in accounting for the acquisition will be deductible for income tax purposes.



Skurka On December 31, 2004, TransDigm 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 acquired businesses 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 for Fluid Regulators and the motor product line; thus, the
values attributed to assets acquired in connection with such acquisitions in the consolidated financial statements are subject to adjustment. Pro forma net sales and results of operations for the Acquisitions, had the Acquisitions occurred at the
beginning of the thirteen week period ended January 1, 2005, are not significant and, accordingly, are not provided.

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
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. Because the participants of these deferred
compensation plans are management personnel of the Company, the cost of the plans, which totaled $(3.0) million and $1.4 million for the thirteen week periods ended December 31, 2005 and January 1, 2005, respectively, was pushed-down to
the Company and recognized as an expense and a capital contribution from TD Group. The amount recognized during the period ended December 31, 2005 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 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 Holdings and
made certain 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. 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 $193.1 million together with substantially
all of the proceeds received from the dividend payment from 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 made by TransDigm Inc. and referred to above were allocated among the
Companys employees receiving such bonuses based on their respective holdings of rollover options and new management options.

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 Holdings 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 Holdings, together with
TransDigm Inc. and its subsidiaries. References to Holdings are to TransDigm Holding Company, 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:



| |  |  | Our substantial leverage, which could adversely affect our financial health.
| | - |  | ----------------------------------------------------------------------------



| |  |  | The terms of the Amended and Restated Senior Credit Agreement, the Indenture governing the 83/8% Senior Subordinated Notes and the TD Group Loan Facility, which may restrict our current and future operations.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 affect 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.
| | - |  | -----------------------------------------------------------------



| |  |  | 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.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We are dependent on our highly trained employees and any work stoppage or difficulty hiring similar employees could adversely affect our business.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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.

Please refer to the other information included in this Quarterly Report on Form 10-Q and to the Annual Report on Form 10-K of Holdings and
TransDigm Inc. for the fiscal year ended September 30, 2005 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, 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 first quarter of fiscal 2006, we
generated net sales of $100.1 million and net income of $13.4 million. In addition, for the first quarter of fiscal year 2006, our EBITDA was $39.3 million, or 39.2% of net sales, and our EBITDA As Defined was $43.1 million, or
43.1% 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, the parent company of TransDigm Inc. and Holdings, 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 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 Holdings referred to in the immediately following paragraph and (ii) TransDigm Inc. and 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.



In connection with the closing of the TD Group Loan Facility, TransDigm Inc. paid a
cash dividend of approximately $98.0 million to 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). 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 $193.1 million, together with
substantially all of the proceeds received from the dividend payment from 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 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 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 October 31, 2005, the
Inspector General issued its most recent draft report. The draft 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 draft 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 draft 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 draft report. In response to the draft report, we offered reasons why we disagree with the Inspector Generals
analysis and why computations related to a voluntary refund contained in the draft 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, at any time after issuance of the final report by the Inspector General, 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.

|(1) | EBITDA represents earnings before interest, taxes, depreciation and amortization. EBITDA As Defined represents EBITDA, plus 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 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 can 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.



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 with certain financial ratios, including a leverage ratio, a fixed charge 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 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

##### Table of Contents

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 our 83/8% 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 costs incurred to integrate Fluid Regulators and the motor product line in fiscal 2006.
|--- | --------------------------------------------------------------------------------------------------



|(3) | Represents the expenses (income) recognized by the Company under a stock option plan and two deferred compensation plans of TD Group that relate to the Companys employees who
participate in the plans. The amount reflected above for the thirteen week period ended December 31, 2005 includes a reversal of previously recorded amounts charged to expense of $3.8 million resulting from the termination of the two deferred
compensation plans of TD Group. In addition, the amount reflected above for the thirteen week period ended December 31, 2005 includes expense recognized by the Company under a new deferred compensation plan of TD Group adopted in December 2005
that relates to the Companys employees who participate in the plan.

|(4) | 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 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.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(5) | 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 Item 7
 Managements Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K for the year ended September 30, 2005. There has been no significant change to our critical
accounting policies during the thirteen week period ended December 31, 2005.

Changes in Results of Operations



Thirteen weeks ended December 31, 2005 compared with thirteen
weeks ended January 1, 2005.



| |  | Net Sales. Net sales increased by $19.9 million, or 24.8%, to $100.1 million for the quarter ended December 31, 2005 from $80.3 million for the comparable
quarter last year, primarily due to: (i) an increase in net sales of $9.8 million attributable to the Acquisitions, which occurred in December 2004, January 2005 and June 2005, respectively, (ii) an increase in commercial OEM sales of
$7.0 million resulting from the higher production rates for The Boeing Company and Airbus S.A.S as well as the business jet market, (iii) an increase in commercial aftermarket sales of $6.8 million resulting from the continuing recovery in the
commercial aerospace market. The aforementioned increase in net sales was partially offset by a decrease in military sales of $3.4 million.

| |  |  | Cost of Sales. Cost of sales increased by $10.1 million, or 24.8%, to $50.9 million for the quarter ended December 31, 2005 from $40.8 million for the
comparable quarter last year. This increase is attributable to increased volume associated with the higher sales of $19.9 million discussed previously.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Cost of sales as a percentage of total sales was approximately 51% for both periods.



| |  |  | Selling and Administrative Expenses. Selling and administrative expenses increased by $4.1 million, or 50.0%, to $12.4 million for the quarter ended
December 31, 2005 from $8.3 million for the comparable quarter last year. The increase is due to: (i) the one-time special bonus of $6.2 million, or 6.2% of net sales, paid to certain members of management, (ii) the higher sales
discussed above and (iii) the Acquisitions. These increases were partially offset by (x) a reversal of previously recorded charges of $3.8 million, or 3.8% of net sales, resulting from the termination in the thirteen week period ended
December 31, 2005 of the Rollover Deferred Compensation Plan and the Management Deferred Compensation Plan, which charges were previously pushed down to the Company, and (y) the decrease of $0.6 million in expense related to the New
Management Deferred Compensation Plan.

Selling
and administrative expenses as a percentage of net sales increased to 12.4% for the quarter ended December 31, 2005 from 10.3% for the comparable quarter last year. The increase in selling and administrative expenses as a percentage of net
sales was primarily due to the one-time special bonus that was paid in the quarter ended December 31, 2005, partially offset by (i) the reversal of previously recorded charges resulting from the termination of the Rollover Deferred
Compensation Plan and the Management Deferred Compensation Plan and (ii) the decrease in expense related to the New Management Deferred Compensation Plan discussed above.



| |  |  | Amortization of Intangibles. There was no change in the amortization of intangibles which totaled $1.8 million for the comparable quarters.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Interest Expense. Interest expense increased by $1.2 million, or 9.4%, to $13.4 million for the quarter ended December 31, 2005 from $12.3 million for the
comparable quarter last year, primarily due to an increase in the interest rates on borrowings under the Amended and Restated Senior Credit Agreement.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Income Tax Provision. Income tax provision as a percentage of income before income taxes was 37.9% for the quarter ended December 31, 2005 and was
comparable to the 37.0% effective tax rate for the comparable quarter last year.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Net Income. Net income increased 24.6% to $13.4 million, or 13.4% of sales, for the quarter ended December 31, 2005 compared to net income of $10.8 million, or 13.4% of
sales, for the comparable quarter last year. Net income as a percentage of sales remained the same despite an increase in selling and administrative costs as a percentage of sales due to the reduction of interest expense as a percentage of sales.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Backlog



As of December 31, 2005, the Company estimated its sales order backlog at $225.0
million compared to an estimated $178.2 million as of January 1, 2005. This $46.8 million increase in sales order backlog is due to an increase of sales order backlog from the acquisition of Fluid Regulators and a motor product line totaling
$26.6 million, as well as an increase in orders among various products from both OEM and aftermarket customers. The majority of the purchase orders outstanding as of December 31, 2005 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 December 31, 2005 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 businesses during the thirteen week periods ended December 31, 2005 and January 1,
2005 were not significant.



Liquidity and Capital Resources



Operating Activities.The Company generated $23.4 million of cash from operating
activities during the quarter ended December 31, 2005 compared to $28.8 million generated during the comparable quarter last year. The decrease of $5.4 million is due to the payment in November 2005 of a one-time special bonus to certain
members of management of $6.2 million discussed previously, partially offset by an increase in the cash generated from other operating activities of $0.8 million.



Investing Activities.Cash used in investing activities decreased to $1.8 million during the quarter ended December 31, 2005
compared to $31.0 million used during the comparable quarter last year, primarily due to the acquisition of Skurka for $30.2 million discussed previously.



Financing Activities. Cash used in financing activities during the quarter ended December 31, 2005 increased to $98.8 million compared to $2.2 million during
the comparable quarter last year, primarily due to the dividend payment to TD Group of $98.0 million.



In connection with the closing of the TD Group Loan Facility, on November 10, 2005, TransDigm Inc. and 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 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 Holdings intend to make such distributions, as permitted, on a quarterly basis.



The TD Group Loan Facility is unsecured and is not guaranteed by 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 earlier to occur of an underwritten public offering of TD Groups common stock and November 10, 2006 (the earlier to occur being referred to as the Trigger Date), the applicable margin percentage is a percentage
per annum equal to 5%. TD Group has filed with the SEC a registration statement on Form S-1 to register the potential sale by certain of TD Groups stockholders of TD Groups common stock. TD Group would not receive any proceeds from the
offering. There can be no assurance, however, that the offering will be consummated. For any day on or after the Trigger

Date and prior to the date 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.



Additional Disclosure Required by Indenture



Separate financial statements of TransDigm Inc. are not presented since Holdings has no operations or assets separate from its investment in TransDigm Inc. and since
the 83/8% Senior Subordinated Notes are guaranteed by Holdings and all direct and indirect domestic restricted
subsidiaries of TransDigm Inc. As of December 31, 2005, the only subsidiary of TransDigm that is not obligated to guarantee the notes is one wholly-owned, foreign subsidiary that has inconsequential assets, liabilities and equity.



Item 3. Quantitative and Qualitative Disclosures About Market Risk



At December 31, 2005, TransDigm Inc. had borrowings under its Amended and Restated Senior Credit Agreement of $289.1 million that were subject to interest rate risk. 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 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 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 Amended and Restated Senior Credit Agreement by approximately $2.9 million based on the amount of outstanding borrowings at
December 31, 2005. The weighted average interest rate on the $289.1 million of borrowings under the Amended and Restated Senior Credit Agreement on December 31, 2005 was 6.58%.



Because the interest rates on borrowings under the Amended and Restated Senior Credit Agreement vary with market conditions, the amount of
outstanding borrowings under 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 83/8% Senior Subordinated Notes is exposed to the market risk of interest rate changes. The estimated fair value of
such notes approximated $418 million at December 31, 2005 based upon quoted market rates.



Item 4. Controls and Procedures



As of
December 31, 2005, Holdings and TransDigm Inc. carried out an evaluation, under the supervision and with the participation of Holdings and TransDigm Inc.s management, including their Chief Executive Officer (Principal Executive
Officer) and Chief Financial Officer (Principal Financial Officer), of the effectiveness of the design and operation of Holdings and TransDigm Inc.s disclosure controls and procedures. Based upon that evaluation, the Chief Executive
Officer and Chief Financial Officer concluded that Holdings and TransDigm Inc.s disclosure controls and procedures are effective to ensure that information required to be disclosed by Holdings and TransDigm Inc. in the reports they file
or submit 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 Holdings and TransDigm Inc.s management, including their 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, Holdings and TransDigm Inc.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 Holdings and TransDigm Inc.s internal controls or other
factors that could significantly affect the internal controls subsequent to the date of Holdings and TransDigm Inc.s evaluations.



Internal Control Over Financial Reporting



There have been no changes in Holdings or TransDigm Inc.s internal control over financial reporting that occurred during the first quarter of the fiscal year
ending September 30, 2006 that have materially affected, or are reasonably likely to materially affect, Holdings or TransDigm Inc.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 pursuing its compliance efforts and utilizing outside assistance for 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.
