Airworthiness Directives; Leonardo S.p.a. Helicopters

Official abstract: The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW189 helicopters. This proposed AD was prompted by reports of cracking on the ejector ducts. This proposed AD would require repetitively inspecting the left-hand (LH) side and right-hand (RH) side ejector ducts, including the exhaust bracket reinforcements and reinforcement plates, and, depending on the results, replacing any affected ejector duct. The FAA is proposing this AD to address the unsafe condition on these products.
