Airworthiness Directives; Airbus Helicopters

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