AD FAA-2013-0737

We are adopting a new airworthiness directive (AD) for certain Airbus Model AS332C, AS332L, AS332L1, AS332L2, and SA330J helicopters. This AD requires inspecting the crimping of the ball joint of the upper- and lower- end-fittings of the main servo-control and, depending on findings, replacing the main servo-control or repairing the ball joint. This AD was prompted by incidents of missing crimping on the ball joints of servo-control end-fittings. The actions of this AD are intended to prevent failure of a main servo-control upper end fitting, and subsequent failure of the flight controls and loss of control of the helicopter.
