What to do
Operators must update their Transport Canada-approved maintenance schedules within 90 days of the directive's effective date to incorporate the tasks, limits, thresholds, and intervals from edition 013.00 of the airworthiness limits publication. If the maintenance schedule already includes previous editions, it must be further updated to include any new or more restrictive requirements. Use of approved revisions or interim updates of the limits publication is allowed for compliance.
Summary
The Canadian Airworthiness Directive CF-2021-27 mandates updates to the maintenance limits and tasks for Airbus Canada Limited Partnership aircraft models BD-500-1A10 and BD-500-1A11. It requires incorporation of the latest edition 013.00 of the published airworthiness limits into the approved maintenance schedule. This directive ensures compliance with Transport Canada regulations to maintain aircraft airworthiness.
What changed
CF-2021-27 replaces the previous directive CF-2021-07 and introduces new or more restrictive maintenance limits and tasks as specified in edition 013.00 of the Airbus Canada airworthiness limits publication. It requires updating the maintenance schedule to include these latest requirements and allows the use of approved revisions or interim replacements of the limits publication for compliance.
Why it matters
This directive is critical for operators and maintenance organizations to ensure that maintenance tasks and limits reflect the most current safety standards approved by Transport Canada. Compliance prevents unsafe conditions and supports continued airworthiness of the affected Airbus Canada BD-500 aircraft models. It also provides clarity on acceptable methods for updating maintenance programs.
