Back in December, the FAA published the System Safety Assessments NPRM. Along with that publication was issued a raft of draft advisory circulars related to specific provisions of Part 25 (Airworthiness Standards for Transport Category Airplanes). Those draft ACs are:
- AC 25.629-1C, Aeroelastic Stability Substantiation of Transport Category Airplanes
- AC 25.671-X, Control Systems—General
- AC 25.901-X, Safety Assessment of Powerplant Installations
- AC 25.933-X, Unwanted In-Flight Thrust Reversal of Turbojet Thrust Reversers
- AC 25.1309-1B, System Design and Analysis
- AC 25.863-X, Flammable Fluid Fire Protection
Comments on each of these draft ACs is due April 24, 2023.
The MARPA Technical Committee reviewed each of these documents and concluded that no comments are warranted based upon the guidance as drafted. Many of the provisions are either inapplicable or are already addressed by PMA holders’ existing processes. However, MARPA’s members have a wide and varied range of expertise and offerings. Therefore, we ask that our members review these ACs (or at least those applicable to your business) and let us know if you think that comments are warranted. If so, please email us your comments no later than April 17 so that we can compile them and file the comments with the FAA.
The insights and efforts of our members are always appreciated as MARPA works to ensure regulations and guidance work for the PMA industry. You can email any comments on these ACs to MARPA President Jason Dickstein at jason@washingtonaviation.com. Please note the relevant AC in your comments.
