## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model H160-B helicopters. This AD was prompted by reports of missing retaining rings on the hinge pins installed on the jettisonable window systems. This AD requires inspecting for missing retaining rings on all the hinge pins installed on the jettisonable window systems and, depending on findings, installing retaining rings found missing. The FAA is issuing this AD to address the unsafe condition on these products.
