AD Proposed for AStar/TwinStar

The FAA has proposed adopting a new Airworthiness Directive (AD) for some Airbus Helicopters Models AS350 and AS355. This proposed AD was prompted by a report of a sliding door that was locked in the open position detaching from the helicopter during flight. This proposed AD would require modifying certain upper rail rollers, installing a label on each sliding door, and prohibit installing affected upper rail rollers or a door having an affected upper rail roller. 

This proposed AD follows a European Union Aviation Safety Agency AD (EASA AD 2023-0131), which was issued July 3, 2023. 

Comments are due March 03, 2025. You can find the proposed AD here.
