Airlines around the world are racing to avoid widespread cancelations by fixing thousands of Airbus aircraft which need immediate maintenance to protect from a problem that injured passengers and caused an emergency landing last month.

American says it expects ‘some delays’ but a quick fix. Delta predicts ‘limited’ impact. United says it’s not affected.

A320 planes are flown by a number of domestic and international airlines, and the required software update could lead to "operational disruptions to passengers and customers," according to Airbus.

Airbus has decided to ground more than 6,000 A320 jets to implement an urgent software update nearly a month after a JetBlue flight suddenly lost altitude mid-flight and sent at least 15 passengers to the hospital.

Airbus identified an apparent issue relating to "intense solar radiation," which "may corrupt data critical to the functioning of flight controls" and recommended an emergency software update to the A320 family of aircraft – a common passenger plane for U.S. carriers.

Airbus and European aviation safety regulators say an aircraft heavily used by commercial airlines around the world needs a software fix to address an issue that contributed to a sudden drop in altitu

One of the world’s largest airplane makers said Friday that intense solar radiation may corrupt data critical to flight controls on a “significant number” of its most popular aircraft, prompting a swift response from several airlines. Airbus attributed the revelation to a recent analysis involving its A320 family of aircraft.

Airlines have averted the threat of major global travel disruption after rushing to fix a software glitch on Airbus A320 jets caused by intense solar radiation. Carriers worked through Friday night and into the weekend after aviation regulators said they must fix the problem before resuming flights.
