Airworthiness Directives; Leonardo S.p.a. Helicopters
Summary
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AB412 and AB412 EP helicopters. This AD was prompted by reports of a cracked main gearbox (MGB) support case. This AD requires revising the existing rotorcraft flight manual (RFM) for the helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
