Summary
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155B and EC 155B1 helicopters. This AD was prompted by a determination that the required forces to jettison the windows exceed the maximum jettisoning effort requirements and the development of a modification of the jettisonable windows. This AD requires replacement of the jettisonable windows and seals on the sliding doors and fixed panels on the left-hand and right-hand sides. This AD also requires the installation of new labels. The FAA is issuing this AD to address the unsafe condition on these products.
