Dear Mr. Filler:

This letter is to inform you that we have granted your petition to exten d Exemption No.

10531 . It explains the basis for our decision , describes its effect, and lists the conditions and

limitations.

The Basis for Our Decision

By letter dated February 6, 2014, you petitioned the Federal Aviation Administration (FAA) on behalf of Pratt & Whitney (P&W) to extend Exemption No. 10531 from §§ 21.142, 21.146, and 21.147 of Title 14, Code of Fed eral Regulations (14 CFR). The exemption allows the manufacture and installation of interface components described in an aircraft type certificate held by P&W’s commercial partners rather than P&W.

In your petition, you indicate that there has been no change in the conditions and reasons relative to public interest and safety that were the basis for granting the original exemption.

The FAA has determined that good cause exists for not publishing a summary of the petition

in the Federal Register because the requested extension of the exemption would not set a precedent, and any delay in acting on this petition would be detrimental to P&W

Our Decision

The FAA has determined that the justification for th e issuance of Exemption No. 10531

remains valid wit h respect to this exemption and is in the public interest. Therefore, under the authority provided by 49 U.S.C. 106(f), 40113 and 44701, which the FAA Administrator has delegat ed to me, I grant Pratt & Whitney (P&W) Division of United Technologies Corpora tion an exemption from §§ 21.142, 21.146 and 21.147 to allow the manufacture and installation of IC described in an aircraft TC held by P&W’s commercial partners rather than

P&W , subject to the conditions and limitations described below.

Conditions and Li mitations

1. Pratt & Whitney (P&W) may ma nufacture interface components (IC) , which i ncludes single articles or ki t s that are part of a product type certificate (TC) un der p arts 23, 25, 27 and 29, and install those components during production on P&W engines under P&W’s production certificate PC 2 . The design data for the IC must be licensed to

P&W and the IC to be installed must be identified on the P&W production limitation record (PLR)

.

2. The IC added to the P&W ’s PLR is limited to airframe components specif ied in condition No. 1. The relief provided by this exemption is limited to the manufacture of IC that is to be installed on P&W engines during engine production , shipped loose with a new engine or, as spare or replacement articles.

3. To exercise the privi leges of this exemption, P&W must apply to the manager of its FAA managing office using FAA Form 8110

- 12, Application for Type Certificate, Production Certificate, or Supplemental Type Certificate, requesting amendment of

P&W’s PLR for the manufacture and installation of IC. The data licensed to P&W must be a complete data package and include design and installation drawings. That data must be made available to P&W and the FAA upon request.

4. The IC listed on P&W’s PLR is limited to IC manufactured by P&W under P&W’s production certificate. The design data must be licensed from the holder of a U.S. TC (including an FAA

- validated TC) for the aircraft on which the P&W engine is to be

installed.

5. The application by P&W to its FAA managing office to amend its PLR must contain the following information:

a. A comprehensive description of the scope of the proposed manufacturing and installation activity for the IC on each affected engine model under the provisions of this exemption.3

b. A specific description of the IC to be installed on each affected P&W engine model, including the part number. Kits combining IC must define the

individual IC included in the kit.

c. The licensing agreement between P&W and the holder of the TC that specifically identifies the IC to be insta lled.

d. A description of the documentation to be maintained by P&W identifying the IC by its associated TC , P&W’s supplier of the IC (if applicable), and the P&W product on which the IC is installed.

6. The holder of type design data identifying the IC install ed on the P&W product under this exemption retains all the continuing airworthiness responsibilities for the IC. P&W is responsible for all issues related to quality, manufacturing, and installation of the IC by P&W. The P&W quality manual must include a description of how those responsibilities will be separated, identified, and fulfilled by P&W and the holder of

the TC identifying the IC.

7. When exercising the privileges of this exemption, the IC may only be installed under the provisions of P&W’s produc tion certificate.

8. P&W must have procedures and processes in place to ensure the engine, notwithstanding the installed IC, conforms to its approved type design, the IC conforms to its approved type design data, and the P&W product with the installed IC

is in a condition for safe operation.

9. Prior to manufacturing and installing IC on an engine under the provisions of this exemption, P&W must receive confirmation from its FAA certificate managing office that the FAA Transport Airplane Directorate and the FA A Engine and Propeller Directorate have determined that any component P&W intends to manufacture and install under the provisions of this exemption is an IC and that installing the IC during engine manufacture provides a level of safety that is equivalent to that achieved by installation of the IC after engine manufacture.

10. P&W must amend its quality manual to indicate that any FAA airworthiness approval documentation issued for an engine containing IC manufactured and installed under the provisions of thi s exemption must specify that the IC was installed on the product under a licensing agreement.

11. Prior to the issuance of any FAA Form 8130

- 3 for a P&W engine manufactured under the P&W quality system and containing IC manufactured and installed under the

p rovisions of this exemption, P&W must specify in block 13 of the form that:

a. the IC was installed on the engine during manufacture in accordance with this Exemption No.,4

b. the IC manufactured and installed under the exemption conforms to its type design, an d

c. the engine, excluding the IC installed, conforms to its type design.

12. The privileges of this exemption are extended to P&W consortium engines when the engines are manufactured under P&W's quality system and completed as a product

under P&W ’s production c ertificate. This exemption does not apply when P&W is manufacturing components of a consortium product and the engine is completed under a separate production certificate.

13. Before exercising the privileges of this exemption, P&W must have procedures for

d ispositioning discrepancies with the IC. Any authority granted by the TC holder in the licensing agreement, allowing for nonconforming material dispositions to be made by P&W, must be documented in P&W’s quality procedures. P&W has no authority

to amend the type design of the IC. All changes to the type design must be made by the design approval holder (i.e., through maintenance review board action).

14. P&W’s manuals relevant to the exempted activity, such as maintenance/operation manuals, and parts catal ogs, must be revised to reflect the exempted activity.

The Effect of Our Decision

Our decision extends the termination date of Exemption No. 10531 to May 31, 2016 unless

s ooner superseded or rescinded.

Sincerely,

/s/
