What to do
Affected operators must complete the new or more restrictive maintenance tasks and limitations from the Bombardier TLMC Part 2 AWL within the specified thresholds, repeat intervals, or discard times starting from the effective date of June 6, 2024. These tasks may be integrated into the approved maintenance schedule with proper identification referencing AD CF-2024-17. Deviations to certain tasks require Transport Canada Civil Aviation approval.
Summary
Canadian Airworthiness Directive CF-2024-17 is issued for Bombardier Inc. model BD-100-1A10 aeroplanes, including Challenger 300 and Challenger 350 variants. It mandates compliance with updated Time Limits/Maintenance Checks (TLMC) and Airworthiness Limitations (AWL) as specified in the latest Bombardier TLMC publications. This directive ensures continued airworthiness by enforcing new or more restrictive maintenance tasks and intervals.
What changed
CF-2024-17 introduces new and more restrictive maintenance tasks and limitations in Part 2 AWL of the Bombardier TLMC manuals for Challenger 300 and Challenger 350 aircraft. These changes include added tasks, reduced thresholds or repeat intervals, revised inspection methods, and reduced discard times. Operators must now comply with these updated requirements within specified intervals or discard times.
Why it matters
This directive is critical for operators, maintenance organizations, and compliance teams to maintain the safety and airworthiness of affected Bombardier aircraft. Non-compliance could lead to unsafe conditions and regulatory violations. Incorporating these updated limitations into approved maintenance schedules streamlines compliance and ensures traceability of mandatory actions.
