Airworthiness Directives; Bell Helicopter Textron, Inc. Model 206A, 206A-1, 206B, 206B-1, 206L, 206L-1, and 206L-3 Series Helicopters Federal Register ↗
Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to Bell Helicopter Textron, Inc. Model 206A, 206A-1, 206B, 206B-1, 206L, 206L-1, and 206L-3 series helicopters. This action requires initial and repetitive inspections of the swashplate for cracks in the swashplate support assembly fillet radius area and replacement, if necessary. This amendment is prompted by reports of cracks found in the swashplate support assembly fillet radius area near the base. The actions specified in this AD are intended to prevent failure of the swashplate support assembly, loss of control of the main rotor system, and subsequent loss of control of the helicopter.
