The Federal Aviation Administration is issuing a new airworthiness directive that mandates inspections and potential repairs on specific Airbus Helicopters Model H160-B aircraft. The rule targets helicopters modified with a specific supplemental type certificate, focusing on the jettisonable window system used to eject windows in emergencies.

Why it matters: If the locking fingers or retaining rings fail, operators might not be able to jettison a window quickly enough to evacuate passengers in an emergency. While this specific safety issue affects a very small number of aircraft, ensuring these mechanisms work correctly is critical for occupant survival in crash scenarios involving fire or water.

Who it affects

  • Owners and operators of eight Airbus Helicopters Model H160-B helicopters registered in the U.S. that have been modified with STC SR00223IB.

This rule was issued by the Federal Aviation Administration; you should check the original document at regulations.gov under Docket No. FAA-2026-2283 before relying on it for compliance purposes.
