Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This proposed AD was prompted by reports of corrosion on attachment screws and fittings fastening the main gearbox (MGB) suspension bars to the fuselage. This proposed AD would require inspecting the affected parts and associated frame bores for discrepancies, and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
