## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain serial-numbered Leonardo S.p.a. Model AW119 MKII helicopters. This AD was prompted by the discovery that the passenger cabin windows (windows) on a batch of helicopters were improperly installed during production. This AD requires removing and reinstalling the windows. The FAA is issuing this AD to address the unsafe condition on these products.
