BANGKOK, 2 December 2025: Asian airlines have completed or are very close to finishing the mandatory software upgrade on their A320 fleets, to comply with a recent urgent Airworthiness Directive (AD) issued by the European Union Aviation Safety Agency (EASA) for the Airbus A320 family aircraft.
The update was required to address a potential software vulnerability in the Elevator Aileron Computer (ELAC) system and was detailed in an Airbus update on A320 Family precautionary fleet action released on 28 November 2025
The Airbus statement: “Analysis of a recent event involving an A320 Family aircraft has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls.
“Airbus has consequently identified a significant number of A320 Family aircraft currently in service which may be impacted. Airbus has worked proactively with aviation authorities to request immediate precautionary action from operators via an Alert Operators Transmission (AOT) to implement available software and/or hardware protection and ensure the fleet is safe to fly.
“The AOT was reflected in an Emergency Airworthiness Directive from the European Union Aviation Safety Agency (EASA). Airbus acknowledges these recommendations will lead to operational disruptions to passengers and customers. We apologise for the inconvenience caused and will work closely with operators, while keeping safety as our number one and overriding priority.”
