The Federal Aviation Administration is asking for comments on a proposed rule that would require repetitive inspections of Airbus A330 airplanes. The proposal targets cracks found on the sloping rib, a structural component on the wing.

Why it matters: This is a routine safety update based on findings from the European regulator. It ensures that cracks in a specific structural part are caught early so they don’t grow. The effect is limited to maintenance schedules for owners of the affected Airbus models. The FAA notes it has no definitive data on the cost of repairs if damage is found, so actual costs could be higher depending on what mechanics discover during the inspection.

Who it affects

  • Owners and operators of 37 Airbus A330-841 and A330-941 airplanes registered in the United States.

This notice comes from the Federal Aviation Administration via the Federal Register; you should check the original document at regulations.gov under Docket No. FAA-2026-4639 before relying on it.
