Airworthiness Directives; Various Restricted Category Helicopters

Summary

We are adopting a new airworthiness directive (AD) for Arrow Falcon Exporters, Inc. (AFE), Rotorcraft Development Corporation (RDC), and San Joaquin Helicopters (SJH) Model OH-58A, OH-58A+, and OH-58C helicopters to require inspecting the main rotor mast (mast) for a crack. This AD is prompted by two reported failures of the mast from corrosion-initiated fatigue cracking. The actions specified by this AD are intended to prevent failure of the mast and subsequent loss of control of the helicopter.
