## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2020-13-02, which applies to certain Leonardo S.p.A. Model A119 and AW119 MKII helicopters. AD 2020-13-02 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 duplex bearing, T/R plug threads, and nut threads. Depending on the inspection results, AD 2020-13-02 requires corrective actions and reporting information. Since the FAA issued AD 2020-13-02, Leonardo S.p.a. issued updated service information. This proposed AD would retain the requirements of AD 2020- 13-02 except the reporting requirement, update the service information, and require repeating the inspection. The FAA is proposing this AD to address the unsafe condition on these products.
