What to do
Affected operators must incorporate the new or more restrictive limitations from the specified Bombardier TLMC revisions and temporary revisions into their approved maintenance schedules by the effective date of June 6, 2024. They must complete all updated tasks within the defined thresholds, repeat intervals, or discard times. For certain inspections, such as the Horizontal Stabilizer Trim Actuator, a phase-in period of up to 12 years applies depending on part rework or manufacture date.
Summary
Canadian Airworthiness Directive CF-2024-16 addresses time limits and maintenance checks related to airworthiness limitations for Bombardier Inc. model CL-600-1A11, CL-600-2A12, and CL-600-2B16 aeroplanes, including Challenger 600, 601, 604, 605, and 650 series. This directive mandates compliance with updated or more restrictive maintenance tasks as defined in the Bombardier Time Limits/Maintenance Checks (TLMC) publications approved by Transport Canada Civil Aviation. It ensures continued airworthiness by enforcing mandatory maintenance actions and inspections.
What changed
CF-2024-16 introduces new and more restrictive airworthiness limitations in Part 2 of the Bombardier TLMC publications, including added tasks and revised thresholds, repeat intervals, inspection methods, and discard times. It requires operators to complete these updated maintenance tasks within specified limits or discard times. The directive also clarifies tolerances for certain tasks and provides a phase-in period for specific inspections related to the Horizontal Stabilizer Trim Actuator.
Why it matters
This directive is critical for aviation professionals as it enforces compliance with updated maintenance requirements that directly impact aircraft safety and airworthiness. Operators and maintenance organizations must adjust their approved maintenance schedules to incorporate these changes, ensuring inspections and tasks are performed timely to prevent unsafe conditions. Non-compliance could lead to regulatory violations and increased safety risks.
