Airworthiness Directives; Leonardo S.p.a. Helicopters
Summary
The FAA is adopting a new airworthiness directive (AD) for Leonardo S.p.a. Model AB139 and AW139 helicopters with certain main rotor blades installed. This AD was prompted by a report of an in- flight loss of a main rotor blade (MRB) tip cap. This AD requires inspecting the MRB tip cap for disbonding. The FAA is issuing this AD to address the unsafe condition on these products.
