EASA AD CF-2024-41
Time Limits/Maintenance Checks — Airworthiness Limitations (ALI)
Summary
Canadian Airworthiness Directive CF-2024-41 addresses time limits and maintenance checks related to Airworthiness Limitations (ALI) for Mitsubishi Heavy Industries RJ Aviation ULC (formerly Bombardier Inc.) 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. Operators must now comply with these updated maintenance requirements to maintain airworthiness.
Why It Matters
This directive is critical for aviation professionals as it enforces updated maintenance standards that directly impact aircraft safety and regulatory compliance. Operators and maintenance organizations must adjust their maintenance programs to incorporate the new or more restrictive ALI tasks to avoid unsafe conditions. Compliance ensures the aircraft remain legally airworthy under Canadian Aviation Regulations.
What To Do
Affected operators must complete the new or more restrictive ALI tasks specified in MHIRJ MRM CSP B-053 Part 2, revision 27, within 30 days of the directive's effective date of 19 December 2024. Compliance can also be met by following any superseding Temporary Revisions or later approved revisions of the maintenance manual. Operators should coordinate with Transport Canada for any alternative means of compliance if needed.
