Time Limits / Maintenance Checks — Certification Maintenance Requirements and Airworthiness Limitations — Amendment
Summary
EASA Airworthiness Directive 2025-0005 is an amendment addressing time limits and maintenance checks for ATR 42-400 and ATR 42-500 aeroplanes. It mandates compliance with the updated Certification Maintenance Requirements and Airworthiness Limitations as specified in the ATR 42 Time Limits Document Temporary Revision 18.1. This directive ensures continued airworthiness by updating maintenance tasks and intervals for these aircraft models.
What Changed
This amendment introduces new and/or more restrictive maintenance tasks and thresholds through the Temporary Revision 18.1 of the ATR 42 Time Limits Document. It updates the previously required tasks from Revision 18 and requires operators to comply with the latest maintenance instructions. The directive does not supersede but complements the earlier EASA AD 2024-0052.
Why It Matters
This directive is critical for aviation professionals as it ensures that maintenance programs reflect the latest safety standards and airworthiness limitations for ATR 42 aircraft. Operators and maintenance organizations must update their maintenance programs to avoid unsafe conditions and regulatory non-compliance. It helps maintain aircraft safety and operational reliability by enforcing timely and appropriate maintenance actions.
What To Do
Operators of ATR 42-400 and ATR 42-500 aeroplanes must accomplish all applicable maintenance tasks specified in Temporary Revision 18.1 within the defined thresholds and intervals starting from 21 January 2025. Any discrepancies found during maintenance must be corrected before the next flight following ATR instructions or approved alternatives. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months of the effective date to incorporate the new limitations and tasks.
