Airbus has instructed airlines worldwide to implement an urgent software change on roughly 6,000 A320-family aircraft after investigators traced an October in-flight incident to corrupted flight-control data, likely caused by intense solar radiation. European regulators followed with mandatory directives requiring operators to revert affected aircraft to an earlier software load before their next flight, prompting airlines to begin slotting rapid turn-round updates into already dense schedules.
The recall stems from an October 30 event involving a JetBlue A321 operating near the northeastern United States. According to regulator summaries, the aircraft experienced uncommanded flight-control behaviour tied to the elevator and aileron computer chain. The crew diverted, and several passengers were injured during the upset.
