What to do
Operators must replace components before exceeding life limits and perform all maintenance tasks within specified intervals as per the ALS Part 5 Revision 03 starting from 1 December 2021. They must revise their Aircraft Maintenance Programme within 12 months after this date to incorporate these requirements. Any discrepancies found during maintenance must be corrected before the next flight, following Airbus instructions or obtaining approved alternatives if necessary.
Summary
EASA Airworthiness Directive 2021-0253R1 is an amendment addressing fuel airworthiness limitations for Airbus A340 series aeroplanes, including models A340-211 through A340-643. It mandates compliance with the Airbus A340 Airworthiness Limitations Section (ALS) Part 5 Revision 03 to ensure continued airworthiness of fuel system components. The directive applies to all manufacturer serial numbers of the affected aircraft.
What changed
This amendment revises the original EASA AD 2021-0253 by incorporating new and more restrictive maintenance tasks and life limits introduced in Airbus A340 ALS Part 5 Revision 03. It also clarifies that later approved variations of the ALS are acceptable for compliance. The revision supersedes previous requirements from EASA AD 2016-0065 and updates compliance instructions accordingly.
Why it matters
This directive is critical for aviation professionals as it ensures the safe operation of Airbus A340 aircraft by enforcing updated maintenance and replacement schedules for fuel system components. Operators, maintenance organizations, and compliance teams must adhere to these mandatory tasks to prevent unsafe conditions and maintain regulatory compliance. Failure to comply could lead to safety risks and regulatory penalties.
