Europe’s Airbus said on Friday it was ordering a right away software change on a “significant number” of its best-selling A320 family of jets in a move that industry sources said would bring disruption to half the worldwide fleet, or hundreds of jets.
The move should be carried out before the following routine flight, in response to a separate bulletin to airlines seen by Reuters, threatening cancellations or delays during considered one of the busiest travel weekends of the yr in america and beyond.
Airbus said in an announcement a recent incident involving an A320-family aircraft had revealed that intense solar radiation may corrupt data critical to the functioning of flight controls.
“Airbus acknowledges these recommendations will result in operational disruptions to passengers and customers,” it said.
Industry sources said the incident that triggered the unexpected repair motion involved a JetBlue flight from Cancun, Mexico, to Newark, Latest Jersey, on October 30, by which several passengers were hurt following a pointy lack of altitude.
Flight 1230 made an emergency landing at Tampa, Florida, after a flight control problem and a sudden uncommanded drop in altitude, prompting an FAA investigation.
JetBlue and the FAA had no immediate comment.
The European Union Aviation Safety Agency is attributable to issue an emergency directive mandating the fix, Airbus said.
For about two-thirds of the affected jets, the recall will lead to a comparatively transient grounding as airlines revert to a previous software version, industry sources said.
Still, that comes at a time of intense demands on airline repair shops, already tormented by shortages of maintenance capability and the grounding of a whole bunch of Airbus jets attributable to long waiting times for separate engine repairs or inspections.

Lots of of the affected jets can also should have hardware modified, threatening for much longer waits, the sources said.
Some 3,000 A320-family jets were within the air worldwide shortly after the Airbus announcement.
American Airlines and Hungary’s Wizz Air said that they had already identified which of their aircraft would want the software fix. United Airlines said it was not impacted.
American, in an announcement, said about 340 of its 480 A320 aircraft require the software alternative, and it expects the majority of those fixes to be “complete today and tomorrow,” with about two hours required for every plane.
There are around 11,300 A320-family aircraft in operation, including 6,440 of the core A320 model, which first flew in 1987.
The setback appears to beamong the largest mass recalls affecting Airbus in its 55-year history and comes weeks after the A320 overtook the Boeing 737 because the most-delivered model.
The A320 was the primary mainstream jetliner to introduce fly-by-wire computer controls.
The bulletin seen by Reuters traced the issue to a flight system called ELAC (Elevator and Aileron Computer), which sends commands from the pilot’s side-stick to elevators on the rear. These in turn control the aircraft’s pitch or nose angle.
The pc’s manufacturer, France’s Thales said in response to a Reuters query that the pc complies with Airbus specifications and the functionality in query is supported by software that isn’t under Thales’ responsibility.
