Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AW189 helicopters. This proposed AD would require inspecting and altering the emergency flotation system (EFS). This proposed AD is prompted by a report of punctured EFS kits. The actions of this proposed AD are intended to prevent an unsafe condition on these helicopters.
