The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.A. Model AW169 helicopters and certain Leonardo S.p.A Model AW189 helicopters. This AD was prompted by a report of a broken extrusion rubber window seal. This AD requires installation of a reinforcement around the rubber filler wedge where the extrusion rubber window seal meets the door's emergency exit handle. The FAA is issuing this AD to address the unsafe condition on these products.
