Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.a. Model A109C, A109E, A109S, and AW109SP helicopters. This proposed AD was prompted by a report of a quality escape on a batch of main rotor blades (MRBs). This proposed AD would require repetitively tap inspecting certain MRBs, replacing those MRBs, and prohibit installing those MRBs, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
