Airworthiness Directives; Airbus Helicopters (Type Certificate Previously Held by Eurocopter France)

We are superseding airworthiness directive (AD) 2013-08-17 for Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, AS 365 N3, and SA-366G1 helicopters. AD 2013-08-17 required initial and recurring inspections of the 9-degree fuselage frame for a crack and repairing the frame if a crack exists. This new AD modifies the compliance times and expands the inspection area of the 9-inch frame. The actions of this AD are intended to detect a crack in the 9-degree frame to prevent loss of structural integrity and subsequent loss of control of the helicopter.
