We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AW189 helicopters. This AD requires inspecting and altering the emergency flotation system (EFS). This AD is prompted by a report of punctured EFS kits. The actions of this AD are intended to prevent an unsafe condition on these helicopters.
