What to do

Operators must incorporate the revised Appendix A2-00 into their Maintenance Requirements Manual within 30 days of the effective date. Missing Maintenance Review Board tasks must be added within 6 months, with initial task accomplishment phased in according to aircraft usage. Any escalated MRB task intervals must be adjusted to comply with CCMR limitations within 6 months, with task accomplishment completed within 12 months or before the CCMR interval limit, whichever is earlier.

Summary

Maintenance Requirements Manual — Introduction of New Appendix A2-00 — Candidate Certification Maintenance Requirements Interval Limitations is a Canadian Airworthiness Directive (AD CF-2019-44) that applies to Bombardier Inc. models CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25 aeroplanes. This directive mandates the incorporation of a new appendix into the Maintenance Requirements Manual to establish Candidate Certification Maintenance Requirements (CCMR) interval limitations as Airworthiness Limitations. It ensures operators maintain compliance with updated maintenance intervals to uphold aircraft safety.

What changed

This AD introduces a new Appendix A2-00 into Part 2 of the Airworthiness Limitations section of the Maintenance Requirements Manual (CSP B-053). The appendix specifies CCMR interval limitations linked to Maintenance Review Board Report tasks, which must be followed to avoid unsafe conditions. Operators must update their maintenance programs to include all CCMR tasks and adjust any escalated task intervals to align with the new limitations.

Why it matters

This directive is critical for aviation professionals because it enforces strict maintenance interval limitations that prevent unsafe conditions arising from overdue maintenance tasks. Operators and maintenance organizations must track and comply with these CCMR intervals to ensure continued airworthiness and regulatory compliance. Failure to adhere to these requirements could compromise aircraft safety and regulatory standing.
