Airbus A320s Return to Service After Urgent Software Fixes
Most of the world’s Airbus A320 Family aircraft have returned to passenger service following rapid completion of critical software updates mandated by the European Union Aviation Safety Agency (EASA). The agency issued an Emergency Airworthiness Directive on November 28, 2025, requiring operators worldwide to address a vulnerability affecting specific flight-control computers before resuming normal operations. The directive targeted Elevator Aileron Computer (ELAC B L104) units installed on A320 Family aircraft, which Airbus identified as potentially vulnerable to data corruption when exposed to solar radiation. The manufacturer’s Alert Operators Transmission detailed two compliance pathways: uploading the updated L103+ software standard or physically replacing affected ELAC units with serviceable equipment.
