What to do
Operators of affected BD-500-1A10 and BD-500-1A11 aircraft must inspect the MF flexible fuel line assemblies within 9500 flight hours from October 2, 2023. If twisted or damaged fuel lines or shrouds are found, they must be replaced following Airbus Canada Service Bulletin BD500-282019. Compliance with this directive is mandatory before conducting any take-off.
Summary
Airworthiness Directive CF-2023-64 is issued by Transport Canada and applies to Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft with specific serial numbers. The directive addresses twisted Motive Flow (MF) flexible fuel lines installed in early configuration pylon to wing areas, which may cause fuel leaks and fire risks. It mandates inspection and corrective actions to ensure fuel line integrity and safety.
What changed
This new Airworthiness Directive introduces a requirement to inspect the left and right MF flexible fuel line assemblies on affected BD-500-1A10 and BD-500-1A11 aircraft for twisting or damage. If issues are found, the directive requires replacement of the fuel lines or shrouds as per Airbus Canada Service Bulletin BD500-282019. It applies to aircraft not previously inspected under earlier service bulletins.
Why it matters
This directive is critical for aviation professionals because twisted MF fuel lines can abrade and leak fuel, creating a fire hazard due to nearby electrical harness connectors. Operators and maintenance teams must ensure compliance to prevent potential in-flight fuel leaks and associated safety risks. Timely inspections and corrective actions help maintain airworthiness and regulatory compliance.
