Airworthiness Directives; Leonardo S.p.A. Helicopters

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.A. Model AB139 and AW139 helicopters. This AD was prompted by reports of a damaged spare inflation system of a certain life raft kit due to the inappropriate shipment of the parts. This AD requires replacing certain life raft inflation systems and prohibits installing an affected life raft inflation system on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
