Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
Summary
We are publishing a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This AD requires inspecting certain bearings. This AD is prompted by reports of failed bearings with subsequent loss of tail rotor (TR) control. The actions of this AD are intended to address an unsafe condition on these helicopters.
