AD FAA-2026-4641

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200 series airplanes; Model A330-200 Freighter series airplanes; Model A330-300 series airplanes; and Model A330-841 and -941 airplanes. This AD was prompted by a report of an in-service event and relevant investigation which found that, under specific conditions, a dormant failure of a standby fuel pump could lead to a certain amount of fuel being trapped in the aft section of the inner tank that would be unusable. This AD requires repetitive operational checks of the standby fuel pumps and corrective actions and limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
