AD on Tail rotor blades for Eurocopter AS 350 and AS355 Helicopters

Wednesday, March 12th, 2014

The FAA is adopting a new airworthiness directive 2014-04-11 (AD) for Airbus Helicopters Model AS350B, BA, B1, B2, B3, and D, and Model AS355E, F, F1, F2, and N helicopters with certain tail rotor (T/R) blades. This AD requires installing additional rivets to secure each T/R blade trailing edge tab (tab), and inspecting for evidence of debonding of the tab after the rivets are installed. This AD was prompted by reports of T/R blade tab debonding. The actions of this AD are intended to prevent loss of a T/R blade tab, which could result in excessive vibration and loss of control of the helicopter. DATES: This AD is effective April 9, 2014. pdf icon 2014-04-11.pdf
