22 U.S.-registered Airbus A330s face new checks

In a federal proposal published June 4, the FAA is asking Airbus SAS A330-841 and A330-941 operators to carry forward a tighter compliance package. The notice would supersede Airworthiness Directive 2025-04-05, so airlines that already built procedures around the older rule would need to track the new version instead.

The checklist on board

The earlier directive did more than rewrite records. It required revisions to the airplane flight manual, or AFM, and the minimum equipment list, or MEL, along with the removal of previously required limitations. It also called for one-time or repetitive seal integrity tests of each engine bleed air system high pressure valve.

Why airlines feel the difference

The proposal also keeps additional maintenance instructions and corrective actions in the mix, plus repetitive replacement of affected high-pressure valve, or HPV, clips where applicable. For airlines and maintenance crews, that kind of recurring work can affect dispatch decisions, schedule planning and day-to-day operating costs even when the rule is framed as a technical update.
