Airworthiness Directives; Airbus Helicopters

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355NP, EC130B4, and EC130T2 helicopters. This AD requires inspecting the swashplate assembly rotating star to determine whether a ferrule was installed. If a ferrule exists, this AD requires inspecting the rotating star for a crack and removing any cracked rotating star. This AD was prompted by a report that reconditioning the rotating swashplate per a certain repair procedure could result in the rotating star cracking. The actions of this AD are intended to detect a crack in the rotating star and prevent failure of the rotating star and subsequent loss of control of the helicopter.
