Airworthiness Directives; Airbus Helicopters Federal Register ↗

Abstract

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. This AD was prompted by reports of debonding on the leading edge protection of certain part-numbered main rotor blades (MRBs). This AD requires repetitively tap inspecting the MRB and, depending on the results, taking corrective action. This AD also prohibits installing an affected MRB on any helicopter unless its requirements are met. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
