 Exemption No. 10079C

 Regulatory Docket No. FAA-2009-0772

Mr. Craig L. Fabian

Regulatory Compliance Leader 

GE Aviation 

General Electric Company

Cincinnati, Ohio 45215

Dear Mr. Fabian:

This letter is to inform you that we have extended Exemption No. 10079, as amended. It 

explains the basis for our decision, describes its effect, and lists the unrevised conditions and 

limitations.

The Basis for Our Decision

By letter dated September 4, 2013, you petitioned the Federal Aviation Administration (FAA) on 

behalf of General Electric Company (GE) for an amendment to Exemption No. 10079, as 

amended. The FAA acknowledges that the regulations from which GE originally sought and 

received exemption, Title 14, Code of Federal Regulations (CFR), §§ 21.151 and 21.153, are 

now embodied respectively in §§ 21.142 and 21.147. This non-substantive change occurred 

during Amendment 21-92, 74 FR 53387, Oct 16, 2009. The original exemption from §§ 21.151 

and 21.153 allowed amendments to GE’s production limitation record (PLR) to permit the 

manufacture and installation of certain parts which are not part of the type-certificated products 

listed on GE’s PLR. 

In your petition, you requested this exemption be extended for 5 years. The FAA, however, 

finds it in the best interest of safety to review this exemption every 2 years. This allows us to 

ensure that there has been no change in circumstances or regulations from which the exemption 

is granted

In your September 4, 2013 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. However, you also requested that we modify the existing exemption (10079B) by 

completely eliminating “Conditions and Limitations” item 12, or by otherwise modifying that

text to include applicability to “components manufactured under GE’s quality system when 

engines are completed as a product under a foreign production approval pursuant to GE’s 

relationship with CFM International.” Item 12, Conditions and Limitations, provides clear 

scope with respect to applicability of the exemption currently in force. To delete this paragraph 

would introduce unnecessary ambiguity. Also, as specified in 14 CFR 11.81, a petitioner must 

indicate the specific sections of 14 CFR from which an exemption is sought. This means the 

relief you seek, and that which the FAA may grant, must be specific to a 14 CFR regulatory 

requirement. The reference to foreign production approvals, as requested in your petition, has 

broad implications and could reach far beyond 14 CFR requirements. This would exceed FAA 

authority.

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, and amendment to the exemption would 

not set a precedent, and any delay in acting on this petition would be detrimental to GE.

The Effect of Our Decision

Our decision extends the termination date of Exemption No. 10079, as amended, to 

September 30, 2016, unless sooner superseded or rescinded. The conditions and limitations are 

restated below. 

Our Decision

The FAA has determined that the justification for the issuance of Exemption No. 10079, as 

amended, remains valid 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 delegated to me, I 

grant General Electric Company relief from sections §§ 21.142 and 21.147 to the extent 

necessary to allow GE to apply to the FAA to amend its production limitation record to allow the 

manufacture and installation of interface components described in FAA type certificates held by 

an entity other than GE, subject to the following conditions and limitations:

Conditions and Limitations

1. GE may manufacture interface components (IC), which includes single articles or kits 

that are part of a product type certificated under parts 23, 25, 27, and 29, and install those 

components during production on GE engines under GE’s production certificate PC108. 

The design data for the IC must be licensed to GE and the IC to be installed must be 

identified on the GE PLR.
3

2. The IC added to the GE’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 GE engines during engine production. IC manufactured by GE under the 

relief granted in this exemption may be shipped loose with a new engine or as spare or 

replacement articles.

3. To exercise the privileges of this exemption, GE 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 GE’s PLR for 

the manufacture and installation of IC. The data licensed to GE must be a complete data 

package and include design and installation drawings. That data must be made available 

to GE and the FAA upon request.

4. The IC listed on GE’s PLR is limited to IC manufactured by GE under GE’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 GE engine is to be installed. 

5. The application by GE 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 GE engine model, 

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

the kit.

c. The licensing agreement between GE and the holder of the TC that specifically 

identifies the IC to be installed.

d. A description of the documentation to be maintained by GE identifying the IC by its 

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

IC is installed.

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

exemption retains all the continuing airworthiness responsibilities for the IC. GE is 

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

GE. The GE quality manual must include a description of how those responsibilities will 

be separated, identified, and fulfilled by GE 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 GE’s production certificate.
4

8. GE 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 GE 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, GE 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 GE 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. GE 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 GE engine manufactured under the 

GE quality system and containing IC manufactured and installed under the provisions of 

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

a. the IC was installed on the engine during manufacture in accordance with

 Exemption No. 10079, as amended,

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

 and

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

12. The privileges of this exemption may be extended to GE consortium engines when the 

engines are manufactured under GE's quality system and completed as a product under 

GE's production certificate. This exemption does not apply when GE 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, GE 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 

GE, must be documented in GE’s quality procedures. GE 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).
5

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

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

Sincerely,

/s/
