✈️Proposed Airworthiness Directive for Airbus Helicopters EC 155B
Airworthiness Directives; Airbus Helicopters
Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155B and EC155B1 helicopters. This proposed 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 proposed AD would require replacement of the jettisonable windows and seals on the sliding doors and fixed panels on the left-hand and right- hand sides. This proposed AD would also require the installation of new labels. The FAA is proposing this AD to address the unsafe condition on these products.

The estimated financial impact on U.S. operators is up to $922,128, indicating high ongoing operational concerns.
