What to do
Operators of affected ACLP BD-500-1A10 and BD-500-1A11 aircraft must perform initial inspections of the fuel feed system between ribs 5 and 6 before 4000 flight hours or within 850 hours from March 17, 2022, whichever is later. Additional inspections between ribs 6 and 9 must occur before 9500 flight hours. These inspections must be repeated at intervals not exceeding 3000 and 9500 flight hours respectively, with any discrepancies corrected per ACLP SB BD500-282006. Compliance with these requirements is mandatory to continue flight operations.
Summary
Canadian Airworthiness Directive CF-2022-08 addresses fuel feed system damage in Airbus Canada Limited Partnership (ACLP) Model BD-500-1A10 and BD-500-1A11 aircraft. The directive mandates inspections and corrective actions for mechanical wear on engine fuel feed system tubes and connections to prevent fuel imbalance and operational issues. It applies to aircraft with specific serial numbers and references ACLP Service Bulletin BD500-282006 for inspection procedures.
What changed
CF-2022-08 introduces mandatory inspections of the fuel feed system in the collector tank at specified intervals based on aircraft groupings and accumulated flight hours. It requires rectification of any damage found according to ACLP Service Bulletin BD500-282006. This directive serves as an interim action following previous modifications mandated by AD CF-2019-19R1.
Why it matters
This directive is critical for maintaining fuel system integrity and preventing fuel imbalance that can degrade aircraft performance and increase pilot workload. Compliance ensures continued airworthiness and operational safety for affected ACLP BD-500 series aircraft. Maintenance and compliance teams must integrate these inspections into their schedules to meet regulatory requirements and avoid operational disruptions.
