What to do
Operators of Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft must amend their Transport Canada approved maintenance schedules within 90 days of the effective date to incorporate the tasks and limitations from AWL Issue No. 012.01. If maintenance schedules already include previous AWL issues, they must be updated to reflect the new and more restrictive requirements. Continued compliance with future approved AWL revisions is also acceptable.
Summary
Canadian Airworthiness Directive CF-2021-07 mandates updated airworthiness limitations for Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft models. This directive requires incorporation of the latest Airbus Canada Airworthiness Limitations (AWL) Issue No. 012.01 into the approved maintenance schedules. It supersedes the previous AD CF-2020-25 and applies to aircraft serial numbers 50001 and subsequent for BD-500-1A10, and 55001 and subsequent for BD-500-1A11.
What changed
AD CF-2021-07 replaces AD CF-2020-25 and introduces new and more restrictive maintenance tasks and limitations as specified in Airbus Canada's AWL Issue No. 012.01. It requires updating the approved maintenance schedules to include these latest airworthiness limitations, including new tasks and reduced thresholds where applicable. The directive also allows the use of future approved revisions of the AWL publication for compliance.
Why it matters
This directive ensures continued airworthiness and safety by enforcing compliance with the latest mandatory maintenance requirements for the affected aircraft. Operators and maintenance organizations must update their maintenance programs to reflect the new limitations to avoid unsafe conditions. Compliance with these updated airworthiness limitations is critical to meeting regulatory standards and maintaining aircraft certification.
