[Proposed Policy Statement No. ANE-200X-33.3-X]


Policy for Repair and Alteration of Rotating Turbine Engine Life 
Limited Parts

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of availability for proposed policy statement; request 
for comments.

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

SUMMARY: The Federal Aviation Administration (FAA) announces the 
availability of proposed policy for the repair and alteration of 
rotating turbine engine-life limited parts (RTE-LLPs). This proposed 
policy establishes that the FAA will treat all repairs and alterations 
of RTE-LLPs as major repairs and major alterations. We are also 
proposing that all RTE-LLP repair and alteration data must include a 
methodology to assess the life of the repaired or altered part and the 
continued operational safety of the repaired product. This proposed 
policy provides guidance for: (1) Technical substantiation for repair 
or alteration of RTE-LLPs; and (2) Aircraft Certification Offices 
(ACOs) and Designated Engineering Representatives to evaluate and 
approve repair and alteration data.

DATES: Comments must be received by November 14, 2005.

ADDRESSES: Send all comments on the proposed policy to the individual 
identified under FOR FURTHER INFORMATION CONTACT.

FOR FURTHER INFORMATION CONTACT: Karen M. Grant, FAA, Engine and 
Propeller Standards Staff, ANE-110, 12 New England Executive Park, 
Burlington, MA 01803; e-mail: [email protected]; telephone (781) 
238-7119; fax: (781) 238-7199.

SUPPLEMENTARY INFORMATION: 
    Comments Invited: The proposed policy is available on the Internet 
at the following address: http://www.faa.gov/aircraft/draft_docs/. If 
you do not have access to the Internet, you may request a copy by 
contacting the individual listed under FOR FURTHER INFORMATION CONTACT. 
The FAA invites interested parties to comment on the proposed policy. 
Comments should identify the subject of the proposed policy and be 
submitted to the individual identified under FOR FURTHER INFORMATION 
CONTACT. The FAA will consider all comments received by the closing 
date before issuing the final policy.
    We will file in the docket all comments received, as well as a 
report summarizing each substantive public contact with FAA personnel 
concerning this proposed policy. The docket is available for public 
inspection before and after the comment date. If you wish to review the 
docket in person, go to the above address between 9 a.m. and 5 p.m., 
Monday through Friday, except Federal holidays.
    Background: During the past year, we reviewed the technical data 
for numerous RTE-LLP repairs. We observed deficiencies in the data for 
many of these repairs. We also noted that may repairs were improperly 
assessed as minor and were not properly coordinated with the 
appropriate ACOs. This proposed policy would provide guidance on the 
coordination and the technical data needed for RTE-LLP repairs and 
alterations.

(Authority: 49 U.S.C. 106(g), 40113, 44701-44702, 44704).
