Summary
EASA Airworthiness Directive 2017-0222R1 is an amendment affecting ATR 42-400 and ATR 42-500 aeroplanes. It mandates compliance with updated airworthiness limitations and certification maintenance requirements as specified in the ATR42-400/-500 Time Limits Document Revision 11 Temporary revision 01. This directive ensures continued airworthiness by enforcing replacement of life-limited parts and adherence to maintenance tasks.
What Changed
This revision corrects the issue date of the referenced Time Limits Document to 03 May 2017 and retains the requirements of previous ADs 2009-0242 and 2012-0193 until they are cancelled. It introduces new and more restrictive maintenance tasks and life limits for ATR 42-400/-500 models as detailed in the updated Time Limits Document.
Why It Matters
Compliance with EASA Airworthiness Directive 2017-0222R1 is critical for operators and maintenance organizations to prevent unsafe conditions caused by failure to perform mandatory maintenance and part replacements. It ensures that aircraft continue to meet regulatory airworthiness standards, thereby supporting safe operation and regulatory compliance. The directive also streamlines maintenance program updates and record-keeping for affected ATR 42 aircraft.
What To Do
Operators must replace life-limited components before exceeding their life limits and perform all required maintenance tasks within specified intervals starting from 24 November 2017. They are allowed a one-time grace period for certain maintenance tasks as listed in the directive. Additionally, the approved Aircraft Maintenance Program must be revised within 12 months after 24 November 2017 to incorporate the updated limitations and tasks from the Time Limits Document.
