Airworthiness Directives; Airbus Helicopters

FAA / Federal Register · 2021-14692

The FAA proposes to supersede airworthiness directive (AD) 2020-24-03 which applies to certain Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, AS355F1, and AS355F2 helicopters. AD 2020-24-03 requires testing the UP/DOWN switches of a certain part-numbered DUNLOP cyclic stick grip, installing a placard, and revising the existing Rotorcraft Flight Manual (RFM) for your helicopter, or removing the DUNLOP cyclic stick grip. Since the FAA issued AD 2020-24-03, Airbus Helicopters developed a modification procedure for the electrical wiring of the hoist control of the DUNLOP cyclic stick grip. This proposed AD would retain some requirements of AD 2020-24-03 and would also require incorporating the new modification, and removing the placard and the RFM amendment installed previously as required by AD 2020-24-03. The proposed additional actions would be required as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
