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

요약
This amendment supersedes an existing airworthiness directive (AD) applicable to Bell Helicopter Textron, Inc. (BHTI) Model 206A, 206B, 206B-1, 206L, 206L-1, 206L-3, and 206L-4 helicopters, that currently requires an inspection of the main rotor hub trunnion (trunnion) for a mislocated master spline and replacement of any trunnion that has a mislocated master spline. This amendment is prompted by a report that certain main rotor hub trunnions (trunnions) were manufactured with a mislocated master spline. The actions specified by this AD are intended to identify and require replacement of any trunnion with a mislocated master spline to prevent pitch link misalignment, altered cyclic stick control position, loss of the main rotor system, and subsequent loss of control of the helicopter.
