ACTION:
Final rule.
SUMMARY:
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.
DATES:
This AD is effective July 7, 2025.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 7, 2025.
