Airworthiness Directives; Bell Helicopter Textron, Inc. Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 Series Helicopters

摘要

This amendment adopts a new airworthiness directive (AD) that is applicable to Bell Helicopter Textron, Inc. Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 series helicopters. This action requires a one-time inspection for cracks in a portion of the main rotor blade (blade) trailing edge and the inboard trim tab, and replacement of the blade or trim tab as necessary. This amendment is prompted by reports of cracks in the blade trailing edge near the inboard trim tab. The actions specified in this AD are intended to prevent failure of a main rotor blade and subsequent loss of control of the helicopter.
