We propose to adopt a new airworthiness directive (AD) for certain Bell Helicopter Textron (Bell) Model 430 helicopters. This proposed AD would require establishing a life limit for a certain main rotor hub attachment bolt (bolt) and removing from service each bolt that has met or exceeded its life limit. This proposed AD is prompted by a documentation error that omitted the life limit of a certain part- numbered bolt from the Airworthiness Limitations section of the maintenance manual. The proposed actions are intended to establish a life limit for a certain part-numbered bolt to prevent failure of a bolt, failure of a main rotor hub, and subsequent loss of control of a helicopter.
