Airworthiness Directives; Airbus Helicopters

Riepilogo

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.
