## Abstract

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2002-13-51, sent previously to all known U.S. owners and operators of the specified helicopters by individual letters. This AD requires cleaning and inspecting a certain tail rotor (T/R) grip with a magnet to determine if it is made of steel. If it is not made of steel, this AD requires replacing each affected T/R grip with an airworthy, steel T/R grip. This AD is prompted by reports of timed-out T/R grips being improperly remarked and reinstalled on certain helicopters. This unsafe condition, if not detected, could result in failure of the T/R grip and subsequent loss of control of the helicopter.
