EASA AD 2021-0209
SUPERSEDED BY EASA AD 2023-0162
Summary
EASA Airworthiness Directive 2021-0209 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 the Airbus A350 Airworthiness Limitations Section (ALS) Part 5 Revision 05, which covers fuel airworthiness limitations and maintenance tasks. This directive ensures the continued airworthiness of these aircraft by enforcing updated maintenance requirements.
What Changed
EASA Airworthiness Directive 2021-0209 supersedes the previous AD 2020-0268 and introduces new and/or more restrictive maintenance tasks and life limits as specified in Airbus A350 ALS Part 5 Revision 05. It requires operators to replace components before exceeding life limits and to perform maintenance tasks within specified intervals. Additionally, it mandates revising the Aircraft Maintenance Programme to incorporate these updated limitations within 12 months of the effective date.
Why It Matters
This directive is critical for aviation professionals because it ensures the safe operation of Airbus A350 aircraft by enforcing updated fuel system maintenance and life limits. Operators and maintenance organizations must comply to avoid unsafe conditions that could arise from overlooked or outdated maintenance tasks. Compliance also ensures regulatory adherence and prevents operational disruptions due to non-conformance with mandatory airworthiness requirements.
What To Do
Operators of Airbus A350-941 and A350-1041 aircraft must replace components before exceeding their life limits and perform all maintenance tasks within the intervals defined in Airbus A350 ALS Part 5 Revision 05 starting from 29 September 2021. They must revise their Aircraft Maintenance Programme to include these updated tasks and limitations within 12 months of the effective date. Any discrepancies found during maintenance must be corrected before the next flight using Airbus-approved instructions.
