EASA AD 2021-0252R1
Time Limits / Maintenance Checks — Fuel Airworthiness Limitations — ALS Part 5 — Amendment
Summary
EASA Airworthiness Directive 2021-0252R1 is an amendment addressing time limits and maintenance checks related to fuel airworthiness limitations for Airbus A330 aeroplanes. It applies to all Airbus A330 models including A330-201 through A330-941 with all manufacturer serial numbers. The directive mandates compliance with the Airbus A330 Airworthiness Limitations Section (ALS) Part 5 Revision 04 to ensure continued airworthiness.
What Changed
This amendment revises the original AD 2021-0252 by incorporating new and/or more restrictive maintenance tasks and life limits introduced in the latest ALS Part 5 Revision 04. It also clarifies that later approved variations of the ALS are acceptable for compliance. The AD supersedes the earlier EASA AD 2016-0065 related to fuel airworthiness limitations for the Airbus A330.
Why It Matters
This AD is critical for aviation professionals as it ensures that operators and maintenance organizations adhere to updated mandatory maintenance tasks and life limits to prevent unsafe conditions related to fuel system components. Compliance is essential to maintain aircraft airworthiness and regulatory approval, impacting maintenance planning and record-keeping. Failure to comply could lead to operational restrictions or safety risks.
What To Do
Operators must replace components before exceeding their life limits and perform all maintenance tasks within specified thresholds and intervals as defined in ALS Part 5 Revision 04. The Aircraft Maintenance Programme (AMP) must be revised within 12 months after 1 December 2021 to incorporate these requirements. Any discrepancies found during maintenance must be corrected before the next flight, following Airbus instructions or approved alternatives.
