Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, EC130B4, and EC130T2 helicopters. This proposed AD was prompted by reports of an incorrectly installed engine flange on the main gear box (MGB) engine coupling. This proposed AD would require inspecting the MGB engine coupling for correct installation and, depending on the results, corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
