Résumé
This amendment adopts a new airworthiness directive (AD), applicable to Bell Helicopter Textron, Inc. Model 206A, 206B, 206L, 206L-1, and 206L-3 helicopters, that requires a one-time inspection for cracks in the tail rotor drive shaft hanger bearing support brackets (brackets), and repair or replacement, as necessary. This amendment is prompted by reports of cracks in the bend radius of the brackets. The actions specified by this AD are intended to prevent misalignment of the tail rotor drive shaft, failure of the tail rotor drive shaft system, loss of control of the tail rotor, and subsequent loss of control of the helicopter.
