Airbus Warns A320 Fleet Needs Software Fix After Incident

Airbus SE cautioned that more than half of its active A320 jetliner family fleet will need a software fix after a recent incident involving a JetBlue Airways Corp. airliner revealed that “intense solar radiation” could corrupt data that helps maintain functioning flight controls.

The company said more than 6,500 jets in total may be impacted by the required fix, according to a statement sent by the European planemaker on Friday. A separate directive by regulators said the upgrade must happen before an aircraft’s next regular flight.
