Airworthiness Directives; Leonardo S.p.A. Helicopters

We propose to adopt a new airworthiness directive (AD) for certain Leonardo S.p.A. (Leonardo) Model AW169 helicopters. This proposed AD would require replacing the seals, filler wedges, and handles of each emergency exit window. This proposed AD is prompted by a report that a high level of pushing force was required to jettison some windows. The actions of this proposed AD are intended to address an unsafe condition on these products.
