Abstract

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters modified by Supplemental Type Certificate (STC) SR00223IB. This AD was prompted by a report that several self-locking nuts of the window jettisoning system could be loosened by hand due to a non-conformity in the cable kit. This AD requires modifying an affected window into a serviceable window. This AD also prohibits installing an affected window or an affected door on any helicopter modified with STC SR00223IB. The FAA is issuing this AD to address the unsafe condition on these products.
