SUPERSEDED BY EASA AD 2025-0203
Summary
EASA Airworthiness Directive 2023-0157 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A350-941 and A350-1041 aeroplanes. It mandates compliance with the Airbus A350 Airworthiness Limitations Section Part 4 System Equipment Maintenance Requirements Revision 08 to ensure continued airworthiness. This directive updates maintenance tasks and life limits for components on these aircraft models.
What Changed
EASA AD 2023-0157 supersedes previous directives 2021-0130R1 and 2022-0127, introducing new and more restrictive maintenance tasks and life limitations as specified in Airbus A350 ALS Part 4 SEMR Revision 08. It retains prior requirements while incorporating updated thresholds and intervals for maintenance and component replacement.
Why It Matters
This directive is critical for aviation professionals as it ensures the safe operation of Airbus A350 aircraft by mandating updated maintenance procedures and life limits. Operators and maintenance organizations must adhere to these requirements to prevent unsafe conditions and maintain regulatory compliance. Failure to comply could result in grounding or unsafe operation of affected aircraft.
What To Do
Operators must replace components before exceeding life limits and perform all maintenance tasks within specified intervals as per the ALS Revision 08 starting from 14 August 2023. They must revise the approved Aircraft Maintenance Programme within 12 months of the effective date to incorporate these new requirements. Any discrepancies found during maintenance must be corrected before the next flight, following Airbus instructions or contacting Airbus if no instructions exist.
