We are adopting a new airworthiness directive (AD) for Eurocopter France Model SA341G helicopters. This AD requires replacing any rotating star with more than 12,000 hours TIS. This AD was prompted by an analysis and tests performed by the manufacturer that indicate that the life limit of the rotating star should be 12,000 hours time- in-service (TIS). The actions of this AD are intended to prevent failure of the rotating star and subsequent loss of control of the helicopter.

This rule is final. Its effective date is October 19, 2012.
