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 inspecting the main rotor (M/R) hub assembly (hub) phonic wheel lock washer (lock washer) for correct installation and depending on the outcome, repairing or replacing the M/R hub. This proposed AD was prompted by reported occurrences of M/R revolutions per minute ("NR") sensor fluctuations. The actions of this proposed AD are intended to address an unsafe condition on these products.
