Airworthiness Directive 2025-09-13
one-timeAirworthiness Directives; Airbus Helicopters
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD was prompted by a report of a sliding door that was locked in the open position detaching from the helicopter during flight. This AD requires modifying certain upper rail rollers, installing a label on each sliding door, and prohibits installing affected upper rail rollers or a door having an affected upper rail roller. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2025-09-13 applies to
Applies as identified in European Union Aviation Safety Agency AD 2023-0131, dated July 3, 2023.
Whether AD 2025-09-13 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
