Airworthiness Directives; Bell Helicopter Textron Canada Helicopters

We are revising an earlier proposed airworthiness directive (AD) for Bell Helicopter Textron Canada (Bell) Model 222, 222B, 222U, 230, and 430 helicopters, which proposed to require replacing certain servo actuators before further flight. The NPRM was prompted by a collective servo actuator malfunction. This action revises the NPRM by adding new actions. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
