Abstract
This amendment adopts a new airworthiness directive (AD) for the specified Bell Helicopter Textron, Inc. (Bell) helicopters. This action requires visually inspecting each main rotor blade box beam clip (clip) for correct installation. This amendment is prompted by a report of a main rotor blade with an incorrectly installed clip. The actions specified in this AD are intended to prevent a main rotor blade spar crack as a result of an incorrectly installed clip, loss of a main rotor blade, and subsequent loss of control of the helicopter.
