Airworthiness Directive · Amendment 39-23308 · Airbus Helicopters Helicopters
Airbus Helicopters Helicopters
This AD applies to Airbus Helicopters AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, and AS350D helicopters. This AD was prompted by a report of a gap between the bolted assemblies under the attachment fittings of the main gearbox (MGB) suspension bars. This AD requires replacing any affected front and rear attachment fittings, screws, nuts and washers of the MGB suspension bars, and prohibits installing any affected parts unless they are new (never previously installed) parts. The FAA is issuing this AD to address the unsafe condition on these products.
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.
