Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters. This proposed AD was prompted by a report of the inability to operate the jettisoning function of a window due to a blocked jettisoning mechanism. This proposed AD would require removing the jettisonable windows, cleaning the ropes of the jettisonable windows, and performing an operational test of the windows jettison systems. The FAA is proposing this AD to address the unsafe condition on these products.
