PRODUCT: Model AW139 helicopters. SUBJECT: Airworthiness Directive 2012-11-12 ACTION: Final rule; request for comments.
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for the products listed above to determine if the hardware that attaches the upper end of collective control rod C2 to torque tube C3 is properly installed. This AD is prompted by the discovery of an incorrectly attached collective control rod. These actions are intended to prevent separation of the collective control rod from the torque tube, loss of control of the collective pitch, and subsequent loss of control of the helicopter.
DATES: This AD becomes effective July 3, 2012. We must receive comments on this AD by August 17, 2012.
