We are adopting a new airworthiness directive (AD) for Leonardo S.p.A. (Leonardo) Model AW189 helicopters. This AD requires replacing the tail plane lower fitting with an improved tail plane lower fitting. This AD was prompted by reports of cracks on the tail plane fittings of Model AW189 helicopters. The actions of this AD are intended to correct an unsafe condition on these products.
