EASA AD 2020-0136
SUPERSEDED BY EASA AD 2020-0263
Summary
EASA Airworthiness Directive 2020-0136 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting ATR 42-400 and ATR 42-500 aeroplanes. It addresses the certification maintenance requirements and airworthiness limitations as defined in the ATR 42-400/-500 Time Limit Document (TLD) Revision 13. This directive mandates compliance with updated maintenance tasks and life limits to ensure continued airworthiness.
What Changed
EASA Airworthiness Directive 2020-0136 supersedes the previous AD 2017-0222R1 and introduces new and more restrictive maintenance tasks and life limits as specified in TLD Revision 13. It requires operators to replace life-limited parts before exceeding their limits and to perform all maintenance tasks within specified thresholds and intervals. Additionally, it mandates revision of the approved Aircraft Maintenance Programme (AMP) within 12 months to incorporate these updated requirements.
Why It Matters
This directive is critical for aviation professionals because failure to comply with the updated maintenance requirements could lead to unsafe conditions on ATR 42-400 and -500 aircraft. Operators, maintenance organizations, and compliance teams must ensure that maintenance programs reflect the latest airworthiness limitations to maintain regulatory compliance and aircraft safety. It also streamlines compliance recording by allowing AMP revision to demonstrate ongoing adherence to the directive.
What To Do
Operators of ATR 42-400 and ATR 42-500 aircraft must replace life-limited components before exceeding their limits and perform all maintenance tasks as specified in TLD Revision 13 starting from the effective date. They must revise their approved Aircraft Maintenance Programme within 12 months of 2 July 2020 to include the new and/or more restrictive tasks and limitations. Any discrepancies found during maintenance must be corrected before the next flight, and if necessary, ATR must be contacted for approved corrective instructions.
