EASA Airworthiness Directive 2025-0203 is an amendment addressing the Airbus A350-941 and A350-1041 aeroplanes. It updates the Airworthiness Limitations Section Part 4 related to System Equipment Maintenance Requirements to ensure continued airworthiness. This directive applies to all manufacturer serial numbers of the affected Airbus A350 models.
What Changed
This directive supersedes EASA AD 2023-0157 and introduces Airbus A350 ALS Part 4 SEMR Revision 10, which includes new and more restrictive maintenance tasks and life limits. It mandates replacement of components before exceeding life limits and completion of maintenance tasks within specified intervals. The Aircraft Maintenance Programme must be revised within 12 months to incorporate these updated requirements.
Why It Matters
Compliance with this directive is critical to maintaining the safety and airworthiness of Airbus A350 aircraft. Operators and maintenance organizations must adhere to the updated maintenance tasks and life limits to prevent unsafe conditions. The directive ensures that maintenance programs reflect the latest manufacturer-approved limitations and tasks, supporting regulatory compliance and operational safety.
What To Do
Operators must replace components before exceeding life limits and complete all maintenance tasks within the specified thresholds starting from 3 October 2025. Any discrepancies found during maintenance must be corrected before the next flight following Airbus instructions or approved alternatives. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months of the effective date to include the updated tasks and limitations from ALS Part 4 SEMR Revision 10.
