What to do
Operators of affected Airbus A319, A320, and A321 aeroplanes must replace or modify any affected ELAC units with serviceable ELAC B L103+ or other approved units before the next flight after 29 November 2025. They must also update the Aircraft Flight Manual within 7 days of the directive's effective date and ensure no affected ELAC units are installed thereafter. Ferry flights with restrictions are permitted to facilitate compliance.
Summary
EASA Airworthiness Directive 2026-0134 is an airworthiness directive addressing the replacement of the Elevator Aileron Computer (ELAC) on Airbus A319, A320, and A321 aeroplanes. It applies to specific ELAC part numbers associated with these aircraft models and aims to ensure continued safe flight control operation. The directive updates previous requirements related to ELAC replacement and installation.
What changed
EASA Airworthiness Directive 2026-0134 supersedes the previous AD 2025-0268-E and updates the definitions of affected and serviceable ELAC units. It clarifies aircraft configurations subject to the directive, expands acceptable ELAC replacements beyond ELAC B L103+, and provides additional instructions for Aircraft Flight Manual amendments and parts installation requirements.
Why it matters
This directive is critical for aviation professionals because it addresses a potential unsafe condition involving uncommanded elevator movements that could exceed structural limits. Operators and maintenance organizations must comply to prevent flight control malfunctions and ensure aircraft safety. Compliance also avoids regulatory penalties and maintains airworthiness certification.
