Airbus Helicopters
This AD applies to Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters, certificated in any category, as identified in European Union Aviation Safety Agency AD 2023-0131, dated July 3, 2023 (EASA AD 2023-0131).
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.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2023-0131.
(1) Where EASA AD 2023-0131 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2023-0131 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(3) Where the service information referenced in EASA AD 2023-0131 specifies to discard parts, this AD requires removing those parts from service.
(4) Where the service information referenced in EASA AD 2023-0131 specifies to submit certain information to the manufacturer, this AD does not require that action.
(5) This AD does not adopt the “Remarks” section of EASA AD 2023-0131.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
