Airworthiness Directives; Airbus Helicopters

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters. This AD was prompted by a discovery during a maintenance operation that several self-locking nuts of the window jettisoning system could be loosened by hand due to a non-conformity in certain cable kits. This AD requires modifying each affected window into a serviceable window. This AD also prohibits installing an affected window or an affected door on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
