Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters

FAA / Federal Register · 2021-17948

The FAA proposes to adopt a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This proposed AD was prompted by a cracked main rotor stationary swashplate assembly (swashplate assembly). This proposed AD would require visually inspecting the swashplate assembly at specified intervals and depending on the results, removing the swashplate assembly from service. The FAA is proposing this AD to address the unsafe condition on these products.
