 Exemption No. 10926

 Regulatory Docket No. FAA-2013-0934

IAE Manager

Certification & Airworthiness

400 Main Street, M/S 121-10

Dear Mr. Morgan:

This letter is to inform you that we have granted your request for exemption. It transmits our 

decision, explains the basis for our decision, describes its effect, and gives you the conditions 

and limitations of the exemption, including the date it ends.

The Basis for Our Decision

By letter dated October 28, 2013, you petitioned the Federal Aviation Administration (FAA) 

on behalf of International Aero Engines AG (IAE, AG) for an exemption from §§ 21.142 and 

21.147 (14 CFR). That exemption from §§ 21.142 and 21.147 of Title 14, Code of Federal 

Regulations (14 CFR) would allow IAE, AG to amend its production limitation record (PLR) 

to allow the installation of certain interface components (IC) described in an aircraft type 

certificate (TC) not held by IAE, AG. Additionally, IAE, AG requests an exemption from 

§ 21.146 to the extent necessary to manufacture completed engines that do not conform to 

their approved design solely because of the installed IC. 

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

in the Federal Register because the requested exemption would not set a precedent, and any 

delay in acting on this petition would be detrimental to IAE, AG.

The FAA has issued grants of exemption in circumstances similar in all material respects to 

those presented in your petition. In Grant of Exemption Nos. 10079, 10079A, and 10079B 

(copies enclosed), the FAA found that the IC can be installed during production without 

adversely affecting safety provided the conditions and limitations of the exemption are met. 

The manufacturing process and configuration of the IC installation must be documented and 

approved in a manner acceptable to the FAA. This relief is consistent with the agency’s 
2

efforts to refine and develop its regulations and explore processes that realize efficiencies and 

reduce risk. 

Having reviewed your reasons for requesting an exemption, I find that—

• they are similar in all material respects to relief previously requested in the enclosed Grant 

of Exemption Nos. 10079, 10079A, and 10079B;

• the reasons stated by the FAA for granting the enclosed Grant of Exemption Nos. 10079, 

10079A, and 10079B; also apply to the situation you present; and 

• for the reasons stated in Grant of Exemption Nos. 10079, 10079A, and 10079B, a grant of 

exemption is in the public interest.

Our Decision

Under the authority contained in 49 U.S.C. §§ 106(f), 40113 and 44701, which the FAA 

Administrator has delegated to me, I hereby grant International Aero Engines, AG an 

exemption from 14 CFR §§ 21.142, 21.146 and 21.147 (14 CFR) to the extent necessary to 

allow the manufacture and installation of IC described in an aircraft TC not held by IAE, AG, 

subject to the conditions and limitations described below.

Conditions and Limitations 

1. IAE, AG may manufacture IC, which includes single articles or kits that are part of a 

product TC under parts 23, 25, 27 and 29, and install those components during production 

on IAE, AG engines under IAE, AG’s Production Certificate No.114-NE. The design data 

for the IC must be licensed to IAE, AG and the IC to be installed must be identified on the 

IAE, AG PLR. 

2. The IC added to the IAE, AG’s PLR is limited to airframe components specified in 

condition No. 1. The relief provided by this exemption is limited to the manufacture of IC 

that is to be installed on IAE, AG engines during engine production, shipped loose with a 

new engine or, as spare or replacement articles. 

3. To exercise the privileges of this exemption, IAE, AG 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 IAE, 

AG’s PLR for the manufacture and installation of IC. The data licensed to IAE, AG must 

be a complete data package and include design and installation drawings. That data must 

be made available to IAE, AG and the FAA upon request. 

4. The IC listed on IAE, AG’s PLR is limited to IC manufactured by IAE, AG under IAE, 

AG’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 IAE, AG engine is to be 

installed. 
3

5. The application by IAE, AG 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. 

b. A specific description of the IC to be installed on each affected IAE, AG engine model, 

including the part number. Kits combining IC must define the individual IC included in 

the kit. 

c. The licensing agreement between IAE, AG and the holder of the TC that specifically 

identifies the IC to be installed. 

d. A description of the documentation to be maintained by IAE, AG identifying the IC by its 

associated TC, IAE, AG’s supplier of the IC (if applicable), and the IAE, AG product on 

which the IC is installed. 

6. The holder of type design data identifying the IC installed on the IAE, AG product under this 

exemption retains all the continuing airworthiness responsibilities for the IC. IAE, AG is 

responsible for all issues related to quality, manufacturing, and installation of the IC by IAE, 

AG. The IAE, AG quality manual must include a description of how those responsibilities 

will be separated, identified, and fulfilled by IAE, AG 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 IAE, AG’s production certificate. 

8. IAE, AG 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 IAE, AG 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, 

IAE, AG must receive confirmation from its FAA certificate managing office that the FAA 

Transport Airplane Directorate and the FAA Engine and Propeller Directorate have 

determined that any component IAE, AG 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. IAE, AG 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 this 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 IAE, AG engine manufactured under the 

IAE, AG quality system and containing IC manufactured and installed under the provisions of 

this exemption, IAE, AG must specify in block 13 of the form that: 

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

(use the assigned exemption number for this exemption), 

b. the IC manufactured and installed under the exemption conforms to its type design, and 
4

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

12. The privileges of this exemption are extended to IAE, AG consortium engines when the 

engines are manufactured under IAE, AG's quality system and completed as a product under 

IAE, AG’s production certificate. This exemption does not apply when IAE, AG 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, IAE, AG must have procedures for 

dispositioning discrepancies with the IC. Any authority granted by the TC holder in the 

licensing agreement, allowing for nonconforming material dispositions to be made by IAE, 

AG, must be documented in IAE, AG’s quality procedures. IAE, AG 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 material review board (MRB) action). 

14. IAE, AG’s manuals relevant to the exempted activity, such as maintenance/operation manuals, 

and parts catalogs, must be revised to reflect the exempted activity. 

This exemption terminates on February 28, 2016, unless sooner superseded or rescinded.

Sincerely,

/s/
