Advisory Circular 33.87-2, Comparative Endurance Test Method To Show Durability for Parts Manufacturer Approval of Turbine Engine and Auxiliary Power Unit Parts
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Notice of issuance of advisory circular.
SUMMARY:
This notice announces the issuance of Advisory Circular (AC) 33.87-2, Comparative Endurance Test Method to Show Durability for Parts Manufacturer Approval of Turbine Engine and Auxiliary Power Unit Parts. This AC describes a comparative endurance test method to be used for certain turbine engine or auxiliary power unit parts when manufactured under Parts Manufacturer Approval (PMA). This method may be used when PMA applicants introduce changes that could affect the durability of their proposed designs. It may also be used when an applicant has insufficient comparative data to show that the durability of their proposed PMA part is at least equal to the type design. The applicant can use this method when requesting PMA under test and computation, per part 21 of Title 14 of the Code of Federal Regulations, and using the comparative test and analysis approach detailed in Federal Aviation Administration Order 8110.42, Part Manufacturer Approval Procedures.
DATES:
The Engine and Propeller Directorate issued AC 33.87-2 on June 25, 2009.
