Description

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 addresses a safety issue where several self-locking nuts of the window jettisoning system could be loosened by hand due to a non-conformity in the cable kit. The directive requires modifying affected windows into serviceable windows and prohibits installing affected windows or doors on helicopters modified with STC SR00223IB. The AD aims to prevent failure of the jettisoning function of the window, which could result in the inability to evacuate occupants during an emergency.
