FAA Proposes Inspections for Corrosion on Airbus A330 Lavatory Fittings

The Federal Aviation Administration has published a proposed rule that would require airlines to inspect the floor fittings inside lavatories on certain Airbus A330 airplanes. The agency is responding to reports of corrosion on these fittings, which could eventually cause the toilet module to detach. If that happens, it could injure people and block exits during an emergency.

Why it matters: This action addresses a specific mechanical issue that could compromise the structural integrity of a lavatory module. While the risk is real, the proposed fix is relatively low-cost and straightforward. The primary impact is administrative: airlines will need to schedule inspections and track compliance. The FAA estimates the inspection costs at up to $340 per airplane per cycle, with parts costing nothing for the inspection itself. On-condition repairs, if needed, would run about $180 per lavatory.

Who it affects

• Operators of 35 Airbus A330-841 and A330-941 airplanes on the U.S. registry.
