Airbus shares fell sharply on Monday after the planemaker had to resolve a major software glitch impacting nearly half of all operational A320 family of jets over the weekend, with the company noting that a majority of the almost 6,000 planes affected by the issue have received a fix.

Airbus said out of the nearly 6,000 aircraft affected by the glitch, “the vast majority have now received the necessary modifications.”

The planemaker added that it was working with airlines to deliver the necessary modifications to the “less than 100 remaining aircraft” still affected by the issue.
