Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters

FAA / Federal Register · 2020-19709

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 the manufacturer discovering non-conforming threads, resulting in a life limit reduction on multiple landing gear components including threaded hinge pins and main landing gear (MLG) and nose landing gear (NLG) actuator pins. This proposed AD would require a one-time inspection of the landing gear for components with non-conforming threads and removal of any nonconforming threaded hinge pin and MLG and NLG actuator pin. The FAA is proposing this AD to address the unsafe condition on these products.
