EASA AD CF-2022-35
Time Limits / Maintenance Checks — Airworthiness Limitations — Tasks Revision
Summary
Airworthiness Directive CF-2022-35 is issued by Transport Canada Civil Aviation and applies to MHI RJ Aviation ULC model CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25 aeroplanes. This directive mandates revisions to the Airworthiness Limitations tasks as published in the Maintenance Requirements Manual CSP B-053 Part 2. It ensures that operators comply with updated inspection tasks to maintain continued airworthiness.
What Changed
This directive introduces new and more restrictive inspection tasks and revisions to existing Airworthiness Limitations for the specified Bombardier regional jet models. These changes are reflected in Maintenance Requirements Manual CSP B-053 Part 2 Revisions 24 and 25, and Temporary Revision ALI-0758. The directive mandates incorporation of these revised tasks into maintenance programs and adherence to specified inspection intervals.
Why It Matters
Compliance with these updated Airworthiness Limitations is critical to detect potential cracks in principal structural elements, preventing unsafe conditions. Operators, maintenance organizations, and compliance teams must update their maintenance procedures to align with Transport Canada's approved revisions. Failure to comply could compromise aircraft safety and regulatory certification.
What To Do
Affected operators must incorporate the new or revised Airworthiness Limitation tasks into their Maintenance Requirements Manual within 60 days of the directive's effective date. They must then perform the inspections at the thresholds and repeat intervals specified in the updated manual or later approved revisions. Contact Transport Canada for any alternative means of compliance if necessary.
