What to do
Operators must accomplish all maintenance tasks specified in the Airbus A340 ALS Part 3 Revision 05 within the defined thresholds and intervals starting from 29 November 2021. Any discrepancies found during maintenance must be corrected before the next flight using Airbus-approved instructions. Additionally, the Aircraft Maintenance Programme must be revised to incorporate the updated tasks within 12 months after 29 November 2021.
Summary
EASA Airworthiness Directive 2021-0249R1 is an updated regulatory requirement affecting all Airbus A340 models including A340-211, A340-212, A340-213, A340-311, A340-312, A340-313, A340-541, A340-542, A340-642, and A340-643. This directive mandates compliance with the Airbus A340 Airworthiness Limitations Section (ALS) Part 3 Revision 05, which contains mandatory maintenance tasks and certification maintenance requirements to ensure continued airworthiness.
What changed
This revision supersedes the previous EASA AD 2021-0249 and incorporates new and more restrictive maintenance tasks introduced in ALS Part 3 Revision 05. It also allows the use of later approved revisions or variations of the ALS for compliance. The directive retains all previous requirements while specifying updated maintenance thresholds and intervals.
Why it matters
Compliance with EASA Airworthiness Directive 2021-0249R1 is critical for operators and maintenance organizations to maintain the safety and airworthiness of Airbus A340 aircraft. Failure to perform the required maintenance tasks could lead to unsafe conditions. The directive ensures that maintenance programs are updated to reflect the latest manufacturer-approved limitations, helping to prevent potential failures and regulatory non-compliance.
