Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This AD was prompted by the manufacturer discovering nonconforming 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 AD requires 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 issuing this AD to address the unsafe condition on these products.
