What to do
Affected operators must accomplish all applicable maintenance tasks specified in ATR 42 TLD TR 18.3 within the prescribed thresholds and intervals starting from 5 March 2025. Any discrepancies found during maintenance must be corrected before the next flight using approved ATR instructions or by contacting ATR if no instructions exist. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months of the effective date to include the new limitations and tasks.
Summary
EASA Airworthiness Directive 2025-0045 is an amendment addressing the time limits and maintenance checks for ATR 42-400 and ATR 42-500 aeroplanes. It mandates compliance with the updated ATR 42 Time Limits Document Temporary Revision 18.3 to ensure continued airworthiness. This directive applies to all manufacturer serial numbers of these aircraft models.
What changed
This amendment introduces new and/or more restrictive maintenance tasks and intervals as specified in the ATR 42 TLD Temporary Revision 18.3. It updates the certification maintenance requirements and airworthiness limitations without superseding previous ADs 2024-0052 and 2025-0005. The updated tasks invalidate previous instructions from ATR 42 TLD Revision 18 where overlapping.
Why it matters
Compliance with EASA Airworthiness Directive 2025-0045 is critical to maintain the safety and airworthiness of ATR 42-400 and ATR 42-500 aircraft. Operators, maintenance organizations, and compliance teams must incorporate these updated maintenance tasks to avoid unsafe conditions. Failure to comply could lead to operational restrictions or safety risks due to unaddressed maintenance requirements.
