What to do
Operators must replace life-limited components before exceeding their life limits and perform all applicable maintenance tasks within specified intervals starting from 24 November 2017. They must revise their approved Aircraft Maintenance Programme within 12 months after this date to incorporate the new limitations and tasks from the ATR72 Time Limits Document Revision 15. In case of discrepancies found during maintenance, corrective actions must be taken before the next flight according to approved procedures.
Summary
EASA Airworthiness Directive 2017-0223R1 is a regulatory document issued by the European Aviation Safety Agency concerning ATR 72 series aeroplanes, including models ATR 72-101, -102, -201, -202, -211, -212, and -212A. This directive mandates compliance with the updated airworthiness limitations and certification maintenance requirements as specified in Revision 15 of the ATR72 Time Limits Document. It ensures continued airworthiness by requiring replacement of life-limited parts and adherence to maintenance tasks within specified intervals.
What changed
EASA Airworthiness Directive 2017-0223R1 revises the original AD 2017-0223 by correcting the issue date of the referenced Time Limits Document to 02 May 2017. It introduces new and more restrictive certification maintenance requirements and airworthiness limitations tasks as detailed in Revision 15 of the ATR72 Time Limits Document. The AD also allows a one-time grace period for certain maintenance tasks close to or exceeding thresholds.
Why it matters
This directive is critical for operators and maintenance organizations to ensure the safe operation of ATR 72 aircraft by enforcing updated maintenance and life limit requirements. Compliance prevents unsafe conditions that could arise from neglecting mandatory tasks or exceeding component life limits. It also streamlines record-keeping by allowing AMP revisions to demonstrate ongoing compliance with the AD.
