Action
Final rule; request for comments.
Summary
We are adopting a new airworthiness directive (AD) for certain Bell Helicopter Textron, Inc. (Bell), Model 204B, 205A, 205A-1, and 212 helicopters. This AD requires removing a certain part-numbered main rotor (M/R) blade grip (grip) from service. This AD is prompted by an error in a parts manufacturer approval (PMA) that incorrectly allows installation of the grips on the Bell Model 212. The actions specified in this AD are intended to prevent grip failure, separation of the M/R blade, and subsequent loss of control of the helicopter.
