EASA AD 2025-0291
Time Limits / Maintenance Checks — Airworthiness Limitations Section — Amendment
Summary
EASA Airworthiness Directive 2025-0291 is an amendment concerning the Dassault Aviation Falcon 900EX aeroplanes, serial numbers 1 to 119 except 97. It updates the Airworthiness Limitations Section (ALS) in the Aircraft Maintenance Manual, Chapter 5-40, Revision 20, to ensure continued airworthiness through mandatory maintenance tasks and life-limited part replacements. This directive applies to Falcon 900EX aircraft operated under European regulations.
What Changed
EASA Airworthiness Directive 2025-0291 supersedes AD 2024-0035 and introduces new and more restrictive maintenance tasks and limitations in the ALS Revision 20. These changes include updated life limits for components and revised maintenance intervals to enhance safety. Operators must now comply with these updated requirements as specified in the latest ALS revision.
Why It Matters
This directive is critical for aviation professionals as it mandates compliance with updated maintenance requirements to prevent unsafe conditions on Falcon 900EX aircraft. Operators and maintenance organizations must incorporate these changes into their maintenance programs to ensure regulatory compliance and continued airworthiness. Failure to comply could lead to grounding of aircraft or unsafe operation.
What To Do
Affected operators must replace components before exceeding new life limits and perform all maintenance tasks within specified intervals starting from 2 January 2026. They must revise their approved Aircraft Maintenance Programme within 12 months to include the new ALS Revision 20 tasks and limitations. Any discrepancies found during maintenance must be corrected before the next flight, following Dassault's approved instructions.
