Full official abstract
This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters. This AD requires replacing arm clamp screws (screws) in the yaw, roll, pitch, and collective syncro resolvers, and installing a guard bracket on the yaw, roll, pitch, and collective syncro resolvers. This AD is prompted by an operator's report that a yaw control channel jammed during freedom-of-control checks following maintenance. The actions specified by this AD are intended to prevent a jammed flight control and subsequent loss of control of the helicopter.
