EASA AD CF-2025-26
Time Limits/Maintenance Checks — Airworthiness Limitations (ALI) — New/Revised Tasks
Summary
Canadian Airworthiness Directive CF-2025-26 addresses new and revised Airworthiness Limitations (ALI) tasks for MHI RJ Aviation ULC aeroplanes, specifically models CL-600-2C10, CL-600-2C11, CL-600-2D15, and CL-600-2D24. This directive mandates compliance with updated maintenance requirements related to structural inspections and safe life components. The directive aims to ensure continued airworthiness by enforcing stricter inspection intervals and tasks.
What Changed
CF-2025-26 introduces four new ALI tasks and revises four existing ALI tasks in the Maintenance Requirements Manual CSP B-053, Revision 28, Part 2. These changes stem from updated Damage Tolerance Analyses that identified the need for more restrictive inspections to maintain structural integrity. The affected tasks cover areas such as the aft service plug door pressure floor, engine mounts, and main landing gear actuator support fittings.
Why It Matters
This directive is critical for aviation professionals because failure to perform the new and revised ALI tasks within specified intervals could lead to undetected structural failures and compromise aircraft safety. Operators, maintenance organizations, and compliance teams must update their maintenance programs to incorporate these more stringent requirements to avoid regulatory non-compliance and ensure the continued airworthiness of affected aircraft.
What To Do
Affected operators must complete the new and revised ALI tasks within the specified thresholds, repeat intervals, or discard times as outlined in the updated MHIRJ Maintenance Requirements Manual CSP B-053, Revision 28, Part 2. Compliance must be achieved by the effective date of 20 May 2025. Additionally, adherence to any superseding Temporary Revisions or later approved revisions of the manual also satisfies the directive's requirements.
