Airworthiness Directives; Leonardo S.p.A. Helicopters
FAA / Federal Register · 2019-04529
We are adopting a new airworthiness directive (AD) for Leonardo S.p.A. Model AB139, AW139, AW169, and AW189 helicopters. This AD requires removing certain part-numbered and serial-numbered tail rotor (T/R) duplex bearings from service. This AD is prompted by a report of a failed T/R duplex bearing roughness inspection. The actions of this AD are intended to address an unsafe condition on these products.
