## Abstract

This amendment adopts a new airworthiness directive (AD) for the specified Bell Helicopter Textron (BHTC) model helicopters. This action requires certain checks and inspections of the tail rotor blades. If a crack is found, before further flight, this AD requires replacing the tail rotor blade (blade) with an airworthy blade. This amendment is prompted by three reports of cracked blades found during scheduled inspections. The actions specified in this AD are intended to detect a crack in the blade and prevent loss of a blade and subsequent loss of control of the helicopter.
