What to do
Operators of Airbus A330 aircraft must replace components before exceeding their life limits and perform all maintenance tasks within specified thresholds and intervals as outlined in Airbus A330 ALS Part 4 Revision 8. They must revise their Aircraft Maintenance Programme within 12 months after 1 December 2021 to incorporate these updated tasks and limitations. Any discrepancies found during maintenance must be corrected before the next flight using approved Airbus instructions or by contacting Airbus for guidance.
Summary
EASA Airworthiness Directive 2021-0250R1 is an updated directive affecting all Airbus A330 models, including A330-201, A330-202, A330-203, A330-223, A330-223F, A330-243, A330-243F, A330-301, A330-302, A330-303, A330-321, A330-322, A330-323, A330-341, A330-342, A330-343, A330-841, and A330-941. It mandates compliance with the Airbus A330 Airworthiness Limitations Section (ALS) Part 4 Revision 8, which contains system equipment maintenance requirements essential for continued airworthiness. This directive ensures operators maintain updated maintenance tasks and life limits for components to prevent unsafe conditions.
What changed
EASA Airworthiness Directive 2021-0250R1 revises the previous directive 2021-0250 by incorporating the latest Airbus A330 ALS Part 4 Revision 8, which introduces new and more restrictive maintenance tasks and limitations. It also consolidates requirements from earlier directives including EASA AD 2019-0047 and AD 2014-0257R1. Additionally, it allows compliance with later approved variations of the ALS for continued airworthiness.
Why it matters
This directive is critical for aviation professionals as it mandates updated maintenance requirements that directly impact aircraft safety and regulatory compliance. Operators and maintenance organizations must ensure that all Airbus A330 aircraft are maintained according to the latest approved maintenance program, preventing potential unsafe conditions caused by outdated or insufficient maintenance. Compliance with this directive supports regulatory adherence and operational safety.
