Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for Eurocopter France Model SA341G helicopters. This proposed AD is 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 proposed actions are intended to prevent failure of the rotating star and subsequent loss of control of the helicopter.
