Regional Jet models CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25. This directive mandates compliance with updated ALI tasks as defined in the MHIRJ Maintenance Requirements Manual CSP B-053 Part 2, revision 27. The directive ensures continued airworthiness by enforcing mandatory maintenance actions approved by Transport Canada.
What changed
CF-2024-41 introduces new or more restrictive ALI tasks and limitations for the specified Regional Jet models, including added tasks and revisions that reduce thresholds, repeat intervals, or discard times. These changes are incorporated in revision 27 of the MHIRJ MRM CSP B-053 Part 2 dated 15 September 2023.
