Airworthiness Directives; Eurocopter France (Eurocopter) Model AS332C, L, L1, and L2 Helicopters

Özet

This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter model helicopters. This action requires replacing each affected hydraulic pump with an airworthy hydraulic pump. This amendment is prompted by the loss of the proper functioning of a hydraulic pump because of the deterioration of the pump seals and the loss of hydraulic fluid caused by incorrect positioning of the piston liner. The actions specified in this AD are intended to prevent loss of hydraulic power and subsequent loss of control of the helicopter.
