WHEREAS, the Company and the Existing Guarantors have heretofore executed and delivered to the Trustee an indenture
(as supplemented by the First Supplemental Indenture thereto, dated as of December 2, 2009, the “INDENTURE”), dated as of October 6, 2009, providing for the issuance by the Company of
7- 3/4% Senior Subordinated Notes due 2014 (the
“NOTES”) and the guarantees thereof by each of the Existing Guarantors; 
 WHEREAS, the Indenture
provides that under certain circumstances described therein, newly created or acquired Domestic Restricted Subsidiaries shall execute and deliver to the Trustee a supplemental indenture to the Indenture providing for a senior subordinated guarantee
of payment of the Notes by such Domestic Restricted Subsidiary (the “SUBSIDIARY GUARANTEE”); 
 WHEREAS, all
things necessary to make this Supplemental Indenture the legal, valid and binding obligation of the Company, the Existing Guarantors and the Guaranteeing Subsidiary have been done; and 

WHEREAS, pursuant to Section 9.01(g) of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture
without the consent of the Holders of the Notes. 
 NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary covenants and agrees for the equal and ratable benefit of the Holders of the Notes as follows: 

1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the
Indenture. 
 2. GUARANTEE, ETC. The Guaranteeing Subsidiary hereby agrees that from and after the date hereof it
shall be a Guarantor under the Indenture and be bound by the terms thereof applicable to Guarantors and shall be entitled to all of the rights and subject to all the obligations of a Guarantor thereunder. 

3. RATIFICATION OF INDENTURE; SUPPLEMENTAL INDENTURES PART OF INDENTURE. The Indenture is in all respects ratified and
confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and every holder of Notes heretofore or hereafter
authenticated and delivered shall be bound hereby. 

 4. EXECUTION AND DELIVERY. The Guaranteeing Subsidiary agrees that the Guarantee

Notes, any Guarantee, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of the Notes. 
 6. NEW YORK LAW TO
GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE AND THE GUARANTEE GRANTED HEREUNDER WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE
APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

8. EFFECT OF HEADINGS. The Section headings have been inserted for convenience of reference only, are not to be considered part

	Title:	 	AssociateSupplement No. 9, dated as of September 3, 2010

 Exhibit 10.3 

EXECUTION VERSION 

SUPPLEMENT NO. 9 dated as of September 3, 2010 (this “Supplement”), to the Guarantee and Collateral Agreement dated
as of June 23, 2006 (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 from time to time party 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 administrative agent and collateral agent (in such capacity, the “Agent”) for the Secured Parties (as defined therein).

 A. Reference is made to the Credit Agreement dated as of June 23, 2006 (as amended, supplemented or otherwise modified
from time to time, the “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 “Lenders”), and Credit
Suisse AG, as administrative agent and collateral agent (in such capacity, the “Agent”) for the Lenders, as amended by (i) that certain Amendment No. 1, Consent and Agreement dated as of January 25, 2007 and
(ii) that certain Assumption Agreement dated as of February 7, 2007. 
 B. Capitalized terms used herein and not
otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement or the Guarantee and Collateral Agreement, as applicable. 

C. The Grantors have entered into the Guarantee and Collateral Agreement in order to induce the Lenders to make Loans and the Issuing
Bank 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 Subsidiary (a “New Subsidiary”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become
a Subsidiary Guarantor and Grantor under the Guarantee and Collateral Agreement in order to induce the Lenders to make additional Loans and the Issuing Bank to issue additional Letters of Credit and as consideration for Loans previously made and
Letters of Credit previously issued. 
 Accordingly, the Agent and the New Subsidiary agree as follows: 

SECTION 1. In accordance with Section 7.16 of the Guarantee and Collateral Agreement, the 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 the 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. In furtherance of the foregoing, the 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 benefit of the Secured Parties, their successors and assigns, a security interest in and lien on all of the New Subsidiary’s right, title and interest in and to the Collateral (as defined in the Guarantee and Collateral
Agreement) of the New Subsidiary. Each reference to a “Grantor” or a “Subsidiary Guarantor” in the Guarantee and Collateral Agreement shall be deemed to include the New Subsidiary. The Guarantee and Collateral
Agreement is hereby incorporated herein by reference. 
 SECTION 2. The 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. 

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 Subsidiary and the Agent. Delivery of an executed signature page to this Supplement by facsimile transmission or electronic transmission (including in pdf format) shall be as effective as delivery of a manually signed
counterpart of this Supplement. 
 SECTION 4. The New Subsidiary hereby represents and warrants that (a) set forth on
Schedule I attached hereto is a true and correct schedule of the location of any and all Collateral of the New Subsidiary and the New Subsidiary’s organization number (or equivalent) from its jurisdiction of formation, (b) set forth
on Schedule II attached hereto is a true and correct schedule of any and all (i) Equity Interests and debt securities now owned by the New Subsidiary and (ii) Intellectual Property now owned by the New Subsidiary and (c) set forth
under its signature hereto, is the true and correct legal name of the 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 
  

 2 

 
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 Subsidiary shall be given to it at the address set forth under its signature below. 

SECTION 9. The 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.
