EASA AD 2025-0268-E
Flight Controls — Elevator Aileron Computer — Replacement
Summary
EASA Airworthiness Directive 2025-0268-E is an emergency directive addressing the replacement of the Elevator Aileron Computer (ELAC) on Airbus A319, A320, and A321 aeroplanes. It applies to specific models and serial numbers equipped with the affected ELAC B L104. The directive mandates the installation of a serviceable ELAC B L103+ to ensure continued safe flight control operation.
What Changed
This new emergency directive requires immediate replacement of the affected ELAC B L104 units with serviceable ELAC B L103+ units on Group 1 aircraft before the next flight after the effective date. It prohibits the installation of the affected ELAC on any aircraft after modification and forbids modification of Group 2 aircraft into Group 1 configurations. The directive introduces mandatory compliance with Airbus Alert Operator Transmission A27N022-25.
Why It Matters
This directive is critical for aviation professionals because the affected ELAC malfunction can cause uncommanded elevator movements, potentially exceeding the aircraft's structural limits. Operators and maintenance teams must act promptly to prevent unsafe flight conditions and ensure regulatory compliance. Failure to comply could lead to serious safety risks and regulatory penalties.
What To Do
Operators of Group 1 Airbus A319, A320, and A321 aeroplanes must replace or modify each affected ELAC with a serviceable unit before the next flight after 29 November 2025. A ferry flight of up to three flight cycles without passengers is allowed to reach a maintenance location. After replacement, installation of affected ELACs is prohibited, and Group 2 aircraft must not be converted into Group 1 configurations.
