The FAA has proposed adopting a new airworthiness directive (AD) for all LAVIA ARGENTINA S.A. (LAVIASA) Model PA-25, PA-25-235, and PA-25-260 airplanes. LAVIASA is the current holder of the Type Certificate for all PA-25 variants which was previously held by Piper. This proposed AD applies to all serial numbers and thus affects all PA-25 models produced by Piper as well.

The FAA issued AD 2024-23-06 in November 2024 for certain MD Helicopters Model 369, 500N, and 600N helicopters with a pilot interconnecting cyclic torque tube (torque tube) part number 369H7133-7 installed. AD 2024-23-06 was prompted by a report of a seized and damaged roller bearing assembly in the torque tube assembly of an MD369E helicopter. This damage did not allow the torque tube to rotate as designed, which initiated a crack and resulted in an emergency landing.

The FAA has proposed to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited (Bell) Model 407 helicopters. This proposed AD was prompted by a report of a fractured pilot cyclic stick tube and subsequent findings of other pilot cyclic stick tubes with fatigue cracking. This proposed AD would require repetitively inspecting the pilot cyclic stick tube assembly for a crack and, depending on the results, repairing or replacing the pilot cyclic stick tube assembly.

The FAA has proposed to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS-350 helicopters. This proposed AD was prompted by a report of non-conformity of a certain cargo hook. This proposed AD would require inspecting the gap between the filler and the side plates of the affected cargo hook and, depending on the results, replacing the cargo hook.
