The FAA proposes to adopt a new airworthiness directive (AD) for Leonardo S.p.a. Model AB139, AW139, AB412, and AB412 EP helicopters. This proposed AD was prompted by failure of an Emergency Flotation System (EFS) float compartment to inflate during maintenance of the EFS. This proposed AD would require inspecting certain EFSs and depending on the results, marking certain parts or removing certain parts from service, 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.
The agency’s own summary, as published.
