## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to Eurocopter France (Eurocopter) Model SA-365N1, AS-365N2, and SA-366G1 helicopters, that requires initial and repetitive inspections of the tail rotor blade Kevlar tie-bar (Kevlar tie-bar) for cracks or delaminations. This amendment is prompted by a report of delamination of a Kevlar tie-bar. The actions specified by this AD are intended to detect cracks that could lead to delamination of the Kevlar tie-bar, loss of tail rotor control, and subsequent loss of control of the helicopter.
