Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters

Traduzione automatica locale · Lingua originale della fonte

Riepilogo

We are adopting a new airworthiness directive (AD) for Eurocopter Model AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters. This AD requires replacing certain serial-numbered main gearbox (MGB) bevel gear vertical shafts because they are no longer airworthy. Also, this AD requires certain inspections of each MGB bevel gear vertical shaft (shaft) for a crack. Also, this AD requires if there is a crack, replacing the shaft with an airworthy part before further flight. This AD is prompted by two incidents of emergency ditching after warning indications of loss of MGB oil pressure. These actions are intended to detect a cracked shaft, which could result in loss of MGB oil pressure, loss of the MGB lubrication system, and subsequent loss of control of the helicopter.
