Several draft FAA Advisory Circulars are currently open for comment of which MARPA members should take note.
Today the FAA’s Engine and Propeller Directorate released draft AC 33.15-3 Parts Manufacturer Approval (PMA) Metallic Part Material Compliance Using Comparative Test and Analysis Method for Turbine Engines or Auxiliary Power Units. This AC is intended to provide guidance to assist PMA applicants in developing tests to demonstrate the equivalence of materials with that of the type design materials. Continue reading
Lessors’ positions with respect to use of PMA appears to be loosening as lessees demand the right to use PMA, lessors become more familiar with PMA, and the industry continues its shift toward ever greater PMA acceptance. Continue reading
Those who attended MARPA’s inaugural European conference last month in Istanbul were treated to an excellent presentation by Delta Air Lines Manager of Component Engineering and MARPA Air Carrier Committee Chairman Mike Rennick on the impressive reliability benefits of PMA parts in Delta’s fleet. As many know, Delta operates a very diverse fleet of aircraft, … Continue reading
On Monday the FAA released new guidance that provides a method of compliance for the test requirements of 14 CFR § 33.84 (engine overtorque test) when the applicant chooses to run that test as part of the endurance test of § 33.87, as well as information and guidance on the test requirements of § 33.85 (calibration test), § 33.87 (endurance test), and § 33.93 (teardown inspection). Continue reading
The FAA is currently seeking comments on its Draft Advisory Circular Engine Overtorque Test, Calibration Test, Endurance Test, and Teardown Inspection for Turbine Engine Certification (§§ 33.84, 33.85, 33.87, 33.93) and MARPA would like your comments! Continue reading
In January, we wrote in this space about two new FAA Policy Statement proposals aimed at increasing coordination between FAA offices in the cases of certain engine PMA and propeller PMA applications. MARPA is always on the lookout for those potential regulations and policies–whether large or small–that could effect our members. In an effort to … Continue reading
EASA is seeking guidance on how to address PMA parts in engines exposed to volcanic ash. Continue reading
The Modification and Replacement Parts Association (MARPA) is proud to announce that the FAA’s Mark Bouyer will present a special workshop on endurance, vibration and materials at the 2010 MARPA Conference. Bouyer manages PMA policy questions for the FAA’s Engine Directorate. His presentation will answer many of the questions that the industry has raised about how to show compliance with FAA airworthiness standards related to endurance, vibration and materials. Click through for more details. Continue reading
Under the proposed legislation, new aircraft engine emissions standards could have the potential to seriously impair the ability of air carriers and others to profitably fly aircraft. Continue reading
An OEM tale of “support failure” backfires when the air carrier community explains that they do, in fact, have the data to support “that” configuration. The same carriers also explain that they are pleased with the support they receive from the PMA community. Continue reading
