What to do
Operators must replace life-limited parts before exceeding their life limits and perform all maintenance tasks within specified intervals as per the Time Limits Document Revision 8 starting from 24 November 2017. They must revise their Aircraft Maintenance Programme within 12 months after 24 November 2017 to incorporate the updated tasks and limitations. Any discrepancies found during maintenance must be corrected before the next flight, following approved ATR procedures.
Summary
EASA Airworthiness Directive 2017-0221R1 is a regulatory update affecting ATR 42-200, ATR 42-300, and ATR 42-320 aeroplanes. It mandates compliance with Revision 8 of the ATR42-200/-300/-320 Time Limits Document, which includes updated certification maintenance requirements and airworthiness limitations. This directive ensures continued airworthiness by enforcing life limits and maintenance tasks for these aircraft models.
What changed
This revision corrects the issue date of the Time Limits Document to 17 October 2016 and retains the requirements of previous ADs 2009-0242 and 2012-0193. It introduces new and more restrictive maintenance tasks and life limits as specified in Revision 8 of the Time Limits Document. Additionally, it allows a one-time grace period for certain maintenance tasks close to or exceeding thresholds.
Why it matters
Compliance with EASA Airworthiness Directive 2017-0221R1 is critical for operators and maintenance organizations to ensure the safety and airworthiness of ATR 42-200/-300/-320 aircraft. Failure to adhere to the updated maintenance and life limit requirements could lead to unsafe conditions. This directive also streamlines compliance by allowing AMP revisions to demonstrate ongoing adherence to maintenance obligations.
