## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.A. Model A119 and AW119 MKII helicopters. This AD requires inspecting for movement and the tightening torque of the tail rotor (T/R) plug, the installation of the outboard and inboard faces of the T/R duplex bearing, and the condition of the T/R plug threads, nut threads, and T/R duplex bearing. Depending on the inspection results, this AD requires removing parts from service, reassembling the T/R duplex assembly, and reporting information. This AD also prohibits installing a T/R duplex bearing unless it has been inspected. This AD was prompted by findings from a preliminary investigation of a Model AW119 MKII helicopter accident. The actions of this AD are intended to address an unsafe condition on these products.
