## Abstract

We are superseding Airworthiness Directive (AD) 2012-14-11 for Arrow Falcon Exporters, Inc. (AFE), Rotorcraft Development Corporation (RDC), and San Joaquin Helicopters (SJH) Model OH-58A, OH- 58A+, and OH-58C helicopters. AD 2012-14-11 required inspecting the main rotor mast (mast) for a crack. This new AD expands the mast inspection area, changes the inspection to a repetitive inspection, and removes the reporting requirement. The actions in this AD are intended to prevent failure of the mast and subsequent loss of control of the helicopter.
