Summary
The FAA proposes to adopt a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This proposed AD would require determining the accumulated hours time-in-service (TIS) of certain part-numbered main gearbox (MGB) suspension bar attachment fittings (fittings) and bolts, and would establish new life limits. This proposed AD is prompted by the outcome of tests and analyses performed by Airbus Helicopters. The actions of this proposed AD are intended to address an unsafe condition on these products.
