Airworthiness Directives; Leonardo S.p.a. Helicopters

FAA / Federal Register · 2021-15021

The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a Model AW189 helicopters. This proposed AD was prompted by a report of an incorrect connection of the inflation hoses to the tee manifolds of the inflation line on the emergency flotation system (EFS) assembly. This proposed AD would require visually inspecting the yellow sleeves and hoses installed on each EFS assembly and depending on the inspection results, accomplishing the corrective actions in the applicable service information as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
