EASA AD CF-2025-71
Time Limits/Maintenance Checks (TLMC) — New Airworthiness Limitations
Summary
EASA Airworthiness Directive CF-2025-71 is issued for Pratt & Whitney Canada model PW814GA and PW815GA engines. This directive introduces new airworthiness limitations related to time limits and maintenance checks to ensure continued engine safety and reliability. It mandates compliance with updated life limits, inspections, and repair limits as specified in the latest airworthiness limitations manual (ALM) Issue No. 021 dated 08 October 2025.
What Changed
EASA Airworthiness Directive CF-2025-71 supersedes AD CF-2023-73 by updating the life limits, inspection intervals, and repair limits for certain engine components based on recent structural analyses. It requires operators to follow the revised maintenance tasks and thresholds detailed in the updated ALM to address newly identified unsafe conditions. The directive also accepts compliance with any later ALM revisions approved by Transport Canada.
Why It Matters
This directive is critical for aviation professionals as it ensures that engine components do not exceed safe operational limits, preventing potential engine damage or failure. Operators and maintenance organizations must update their maintenance programs to align with the new ALM requirements to maintain regulatory compliance and aircraft airworthiness. Failure to comply could lead to unsafe conditions affecting both engine performance and overall flight safety.
What To Do
Affected operators must ensure that no engine parts are installed or remain installed unless they comply with the updated life limits, maintenance tasks, inspection intervals, and repair limits specified in ALM Issue No. 021 dated 08 October 2025. All required replacements, inspections, or repairs must be completed before the parts reach their new limits. Compliance with these requirements is mandatory as of the effective date, 13 January 2026.
