What to do
Operators of ATR 42-200, ATR 42-300, and ATR 42-320 aircraft must comply with the updated maintenance tasks and life limits specified in the ATR 42 Time Limit Document Revision 09 starting from 31 October 2019. They must replace life-limited parts before exceeding limits and complete all maintenance tasks within prescribed intervals. The approved Aircraft Maintenance Programme must be revised within 12 months of the effective date to incorporate these requirements. A one-time grace period of up to 6 months is allowed for specific tasks nearing or exceeding thresholds.
Summary
EASA Airworthiness Directive 2019-0256 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting ATR 42-200, ATR 42-300, and ATR 42-320 aeroplanes. It mandates compliance with updated airworthiness limitations and certification maintenance requirements as specified in the ATR 42-200/-300/-320 Time Limit Document Revision 09. This directive ensures continued safe operation by enforcing life limits and maintenance tasks for these aircraft models.
What changed
EASA Airworthiness Directive 2019-0256 supersedes the previous AD 2017-0221R1 and introduces new and/or more restrictive maintenance tasks and life limits as defined in the latest Time Limit Document Revision 09. It requires operators to replace life-limited parts before exceeding their limits and to perform maintenance within specified intervals. Additionally, it allows a one-time grace period for certain tasks close to or exceeding thresholds.
Why it matters
This directive is critical for aviation professionals as it ensures the continued airworthiness and safety of ATR 42-200/-300/-320 aircraft by enforcing updated maintenance and life limitation requirements. Operators and maintenance organizations must comply to avoid unsafe conditions and regulatory non-compliance. It also streamlines compliance by allowing AMP revisions to cover ongoing maintenance requirements without needing to record each individual action separately.
