ACTION: Final rule; request for comments. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for various restricted category helicopters originally manufactured by Bell Textron Inc. This AD was prompted by a fatal accident in which an outboard main rotor hub strap pin (pin) sheared off during flight, resulting in the main rotor blade and the main rotor head detaching from the helicopter. This AD requires removing certain pins from service and prohibits installing those pins on any helicopter.

DATES: This AD is effective August 13, 2021. Emergency 2021-15-52, issued on July 8, 2021, which contained the requirements of this amendment, was effective with actual notice. The FAA must receive comments on this AD by September 13, 2021.
