FAA Draft Advisory Circulars Need Your Comment

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.

We will provide a more detailed analysis of this draft AC in the coming days, but want to encourage each of our members to review it and submit comments to the FAA addressing any potential problems you identify–or offering praise if you feel it is a useful document.  MARPA will be offering its own comments, so if you do not wish to file on your own, please feel free to provide us with your thoughts and we will incorporate them into the association’s comments.  These comments are due to the FAA by July 20.

Two other draft ACs are also open for comment and bear review. The first is AC 39-xx Alternative Methods of Compliance. This AC is intended to provide guidance to those applicants seeking approval of an AMOC. This guidance formerly appeared in FAA Order 8110.103A but has since been removed to a stand-alone AC. Comments are due May 30.

The other is AC 23.10 FAA Accepted Means of Compliance Process for 14 CFR Part 23. This AC provides guidance on how to submit applicant proposed means of compliance to the FAA for acceptance by the Administrator in accordance with proposed § 23.10 (which is one section of the current Part 23 proposed rule revision). Comments are due May 13.

Each of these proposed Advisory Circulars should be reviewed for potential effects on the PMA industry. MARPA will be undertaking its own reviews, but we encourage each of our members to do the same, and file such comments as they believe helpful.  All draft materials and FAA contact information can be found at https://www.faa.gov/aircraft/draft_docs/ac/.

If you would like us to incorporate your comments, you should email them to VP  of Government and Industry Affairs Ryan Aggergaard at ryan@washingtonaviation.com
