What to do

Operators must replace components before exceeding life limits and perform all maintenance tasks within specified thresholds and intervals starting from 20 July 2022. Any discrepancies found during inspections must be corrected within the specified compliance times or before the next flight if no time is given. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months of the effective date to incorporate the updated limitations and tasks.

Summary

EASA Airworthiness Directive 2022-0137 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting all Dassault Aviation Mystère-Falcon 900 aeroplanes. It mandates compliance with updated airworthiness limitations and maintenance tasks specified in the Dassault Mystère-Falcon 900 Aircraft Maintenance Manual, Chapter 5-40, Airworthiness Limitations Section, Revision 26. This directive ensures continued safe operation by enforcing mandatory maintenance and life limit replacements.

What changed

EASA Airworthiness Directive 2022-0137 supersedes the previous AD 2020-0115 and introduces a new maintenance task for eddy current inspections of flap tracks 2 and 5. It retains all prior requirements while incorporating new and more restrictive maintenance tasks and life limits as specified in the latest revision of the Airworthiness Limitations Section. Operators must update their approved Aircraft Maintenance Programme accordingly.

Why it matters

This directive is critical for operators, maintenance organizations, and compliance teams to ensure the continued airworthiness and safety of Mystère-Falcon 900 aeroplanes. Failure to comply with the updated maintenance tasks and life limits could lead to unsafe conditions. It also streamlines compliance by allowing AMP revisions to demonstrate ongoing adherence to the AD requirements.
