Airworthiness Directives; Leonardo S.p.a. Helicopters

FAA / Federal Register · 2021-18256

The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109E helicopters. This proposed AD was prompted by reports of cracking in the center fuselage frame assembly in the intersection of the lateral pylon and floor spar at station (STA) 1815 on the left- and right-hand sides. This proposed AD would require repetitive inspections of the intersection of the lateral pylon and floor spar at STA 1815 for cracking and, depending on the findings, repair, as specified in a 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.
