FAA Airworthiness Directive for Airbus SAS A330 Series Standby Fuel Pump Safety

The Federal Aviation Administration (FAA) has issued a regulatory airworthiness directive (AD) targeting Airbus SAS A330 series airplanes to address a critical safety concern: - Government Buyer: - Federal Aviation Administration (FAA), Aircraft Certification Service, Integrated Certificate Management Division - OEM Highlight: - Airbus SAS is the sole Original Equipment Manufacturer (OEM) referenced - Aircraft Models Affected: - Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A330-841, and A330-941 - Products/Services Requested: - Repetitive operational checks of standby fuel pumps - Corrective actions including troubleshooting and replacement of defective parts as specified in EASA AD 20260073 - Unique/Notable Requirements: - Compliance with European Union Aviation Safety Agency (EASA) AD 20260073 - Ongoing, repetitive checks with no specified end date (continuous compliance) - Limits on installation of affected parts under certain conditions - Aimed at preventing fuel entrapment in the aft inner tank and uncommanded dual engine shutdown - Estimated Compliance Cost: - $85 per airplane for 154 U.S.-registered aircraft - No specific part numbers or purchase quantities are provided, as this is a regulatory safety action rather than a procurement for goods or services.

Description

The FAA is issuing 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 addresses a dormant failure of a standby fuel pump that could trap fuel in the aft section of the inner tank, making it unusable. The directive requires repetitive operational checks of the standby fuel pumps, corrective actions, and limits the installation of affected parts under certain conditions to prevent unsafe conditions such as uncommanded in-flight engine shutdown.
