AD on Main Rotor Gearbox for Agusta A109 & A119 Helicopters

The FAA is adopting a new airworthiness directive (AD) 2014-23-02 for certain Agusta Model A109E, A109K2, A119, and AW119 MKII helicopters. This AD requires repetitively performing a magnetic particle inspection of the Gleason crown for a crack. This AD was prompted by a report of a crack that was found on a Gleason crown, which if not detected, could cause damage to or loss of the main rotor drive and subsequent loss of control of the helicopter. DATES: This AD is effective December 26, 2014. pdf icon 2014-23-02.pdf
