Immediate software change on ‘significant number’ of jets to result in disruption to half the global fleet

Airbus said on Friday it was ordering an immediate software change on a “significant number” of its bestselling A320 family of aircraft in a move that industry sources said would bring disruption to half the global fleet, or thousands of jets.

The move must be carried out before the next routine flight, according to a separate bulletin to airlines seen by Reuters, with the UK’s civil aviation authority warning of “some disruption and cancellations” to flights over the coming days.

It also comes during one of the busiest travel weekends of the year in the United States.

Airbus said in a statement a recent incident involving an A320-family aircraft had revealed that intense solar radiation may corrupt data critical to the functioning of flight controls.
