Airbus has issued a progress update following the Alert Operators Transmission (AOT) released on November 28, which called for immediate precautionary action across a segment of the in-service A320-family fleet. The AOT required operators to implement a mandatory software update designed to prevent a rare but serious flight-control malfunction triggered under specific atmospheric conditions.
According to Airbus, implementation is now in its final phase. Of the roughly 6,000 aircraft identified as potentially affected, the overwhelming majority have already received the required modifications. Fewer than 100 aircraft worldwide are still awaiting completion of the update, and Airbus is working closely with operators to ensure these remaining jets are returned to service without delay.
Several major carriers have already finalised the update across their fleets. Lufthansa, British Airways, easyJet, JetBlue, Qantas, and IndiGo are among the airlines that have confirmed full compliance, enabling them to resume normal operations. Many others are expected to complete the process within days as maintenance teams prioritise the upgrade during scheduled ground time.
Airbus emphasised that the prompt response from airlines, supported by regulators, has significantly accelerated the global rollout. The manufacturer added that no in-service aircraft showing the issue remain operational, and operators have managed the process with minimal impact on scheduling thanks to coordinated planning and rapid software deployment.
