EASA AD 2021-0026
SUPERSEDED BY EASA AD 2021-0208
Summary
EASA Airworthiness Directive 2021-0026 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting all Airbus A350-941 and A350-1041 aeroplanes. It mandates compliance with updated System Equipment Maintenance Requirements as specified in Airbus A350 Airworthiness Limitations Section Part 4 Variation 5.1. This directive ensures continued airworthiness by requiring new and more restrictive maintenance tasks and life limit replacements.
What Changed
This directive introduces new and more restrictive maintenance tasks and life limit replacements as defined in Airbus A350 ALS Part 4 Variation 5.1, which were not covered in the previous revision. It updates the approved Aircraft Maintenance Programme to incorporate these changes and invalidates certain instructions from the earlier ALS Part 4 Revision 05 issue 2. EASA AD 2020-0211 remains in effect and is not superseded by this directive.
Why It Matters
For aviation professionals, this directive is critical to maintaining the safety and airworthiness of Airbus A350 aircraft by enforcing updated maintenance requirements. Operators and maintenance organizations must adhere to these new tasks and intervals to prevent unsafe conditions. Compliance ensures regulatory conformity and avoids operational disruptions due to non-compliance with mandatory maintenance instructions.
What To Do
Operators must replace components before exceeding their life limits and perform all applicable maintenance tasks within specified thresholds and intervals as per the Variation. Any discrepancies found during maintenance must be corrected before the next flight using approved Airbus instructions. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months of the effective date to incorporate the new limitations and tasks.
