Airworthiness Directives; Leonardo S.p.a. Helicopters

FAA / Federal Register · 2020-23019

The FAA is adopting a new airworthiness directive (AD) for Leonardo S.p.a. (Leonardo) Model A109E, A109S, A119, AW109SP, and AW119MKII helicopters. This AD requires removing certain main rotor (M/ R) floating ring assemblies from service. This AD also prohibits replacing any washer on any M/R floating ring assembly. This AD was prompted by a report of a washer debonding from the M/R floating ring assembly. The actions of this AD are intended to address an unsafe condition on these products.
