## Summary

We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) 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 proposed AD would require 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 proposed AD is prompted by reports of T/R blade tab debonding. The actions specified by this proposed 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.
