Exhibit 10.7

SUPPLEMENT NO. 1 dated as of September 22, 2011 (this “Supplement”) to the
Guarantee and Collateral Agreement dated as of June 23, 2006, as amended and
restated as of December 6, 2010, and as further amended and restated as of
February 14, 2011 (as amended and supplemented from time to time, the “Guarantee
and Collateral Agreement”), among TRANSDIGM INC., a Delaware corporation (the
“Borrower”), TRANSDIGM GROUP INCORPORATED, a Delaware corporation (“Holdings”),
each subsidiary of the Borrower listed on Schedule I thereto (each such
subsidiary individually a “Subsidiary Guarantor” and collectively, the
“Subsidiary Guarantors”; the Subsidiary Guarantors, Holdings and the Borrower
are referred to collectively herein as the “Grantors”) and CREDIT SUISSE AG, as
collateral agent for the Secured Parties and as administrative agent under each
of the 2010 Credit Agreement and the 2011 Credit Agreement (each as defined
below) (in such capacities, the “Agent”).

A. Reference is made to (a) the Credit Agreement dated as of December 6, 2010,
as amended by Amendment No. 1 dated as of March 25, 2011 (as amended,
supplemented or otherwise modified from time to time, the “2010 Credit
Agreement”), among the Borrower, Holdings, each subsidiary of the Borrower from
time to time party thereto, the lenders from time to time party thereto (the
“2010 Lenders”) and the Agent and (b) the Credit Agreement dated as of
February 14, 2011 (as amended, supplemented or otherwise modified from time to
time, the “2011 Credit Agreement” and, together with the 2010 Credit Agreement,
the “Credit Agreements”), among the Borrower, Holdings, each subsidiary of the
Borrower from time to time party thereto, the lenders from time to time party
thereto (the “2011 Lenders” and, together with the 2010 Lenders, the “Lenders”)
and the Agent.

B. Capitalized terms used herein and not otherwise defined herein shall have the
meanings assigned to such terms in the 2010 Credit Agreement, the 2011 Credit
Agreement or the Guarantee and Collateral Agreement, as the context may require.

C. The Grantors have entered into the Guarantee and Collateral Agreement in
order to induce the Lenders to make Loans and the 2010 Issuing Banks to issue
Letters of Credit. Section 7.16 of the Guarantee and Collateral Agreement
provides that additional Domestic Subsidiaries of the Loan Parties may become
Subsidiary Guarantors and Grantors under the Guarantee and Collateral Agreement
by execution and delivery of an instrument in the form of this Supplement. The
undersigned Subsidiaries (collectively, the “New Subsidiaries” and each, a “New
Subsidiary”) are executing this Supplement in accordance with the requirements
of the applicable Credit Agreement to become Subsidiary Guarantors and Grantors
under the Guarantee and Collateral Agreement in order to induce the Lenders to
make additional Loans and the 2010 Issuing Banks to issue additional Letters of
Credit, and as consideration for Loans previously made and Letters of Credit
previously issued.

Accordingly, the Agent and each New Subsidiary agree as follows:

SECTION 1. In accordance with Section 7.16 of the Guarantee and Collateral
Agreement, each New Subsidiary by its signature below becomes a Grantor and
Subsidiary Guarantor under the Guarantee and Collateral Agreement with the same
force and effect as if originally named therein as a Grantor and Subsidiary
Guarantor, and each New Subsidiary hereby (a) agrees to all the terms and
provisions of the Guarantee and Collateral Agreement

--------------------------------------------------------------------------------

applicable to it as a Grantor and Subsidiary Guarantor thereunder and
(b) represents and warrants that the representations and warranties made by it
as a Grantor and Subsidiary Guarantor thereunder are true and correct in all
material respects on and as of the date hereof (except for any representation or
warranty that is limited by its terms to an earlier specified date). In
furtherance of the foregoing, each New Subsidiary, as security for the payment
and performance in full of the Secured Obligations (as defined in the Guarantee
and Collateral Agreement), does hereby create and grant to the Agent, its
successors and assigns, for the ratable benefit of the Secured Parties, their
successors and assigns, a security interest in and lien on all of such New
Subsidiary’s right, title and interest in and to the Collateral (as defined in
the Guarantee and Collateral Agreement) of such New Subsidiary. Each reference
to a “Grantor” or a “Subsidiary Guarantor” in the Guarantee and Collateral
Agreement shall be deemed to include such New Subsidiary. The Guarantee and
Collateral Agreement is hereby incorporated herein by reference.

SECTION 2. Each New Subsidiary represents and warrants to the Agent and the
other Secured Parties that this Supplement has been duly authorized, executed
and delivered by it and constitutes its legal, valid and binding obligation,
enforceable against it in accordance with its terms subject to applicable
bankruptcy, insolvency or similar laws affecting creditors’ rights generally and
to general principles of equity.

SECTION 3. This Supplement may be executed in counterparts (and by different
parties hereto on different counterparts), each of which shall constitute an
original, but all of which when taken together shall constitute a single
contract. This Supplement shall become effective when the Agent shall have
received counterparts of this Supplement that, when taken together, bear the
signatures of the New Subsidiaries and the Agent. Delivery of an executed
signature page to this Supplement by facsimile or other electronic transmission
shall be as effective as delivery of a manually signed counterpart of this
Supplement.

SECTION 4. Each New Subsidiary hereby represents and warrants that (a) set forth
on Schedule I attached hereto is a true and correct schedule of each location
where any Collateral of such New Subsidiary is stored or otherwise located, set
forth on Schedule II is a true and correct schedule of the Pledged Collateral of
such New Subsidiary and set forth on Schedule III is a true and correct schedule
of the Intellectual Property of such New Subsidiary, and (b) set forth under its
signature hereto, is the true and correct legal name of such New Subsidiary, its
jurisdiction of formation and the location of its chief executive office.

SECTION 5. Except as expressly supplemented hereby, the Guarantee and Collateral
Agreement shall remain in full force and effect.

SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 7. In case any one or more of the provisions contained in this
Supplement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein and in the Guarantee and Collateral Agreement shall not in any way be
affected or impaired thereby (it being understood that the invalidity of a
particular provision in a particular jurisdiction shall not in and of itself

--------------------------------------------------------------------------------

affect the validity of such provision in any other jurisdiction). The parties
hereto shall endeavor in good-faith negotiations to replace the invalid, illegal
or unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

SECTION 8. All communications and notices hereunder shall be in writing and
given as provided in Section 7.01 of the Guarantee and Collateral Agreement. All
communications and notices hereunder to the New Subsidiaries shall be given to
it at the address set forth under its signature below.

SECTION 9. Each New Subsidiary agrees to reimburse the Agent for its reasonable
out-of-pocket expenses in connection with this Supplement, including the
reasonable fees, other charges and disbursements of counsel for the Agent.

--------------------------------------------------------------------------------

IN WITNESS WHEREOF, the New Subsidiaries and the Agent have duly executed this
Supplement to the Guarantee and Collateral Agreement as of the day and year
first above written.
