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 altitude of a JetBlue plane last month, the manufacturer and European aviation safety regulators said Friday.

The step may result in some flight delays as U.S. travelers return home from the Thanksgiving holidays.

Airbus said an analysis of the JetBlue incident revealed intense solar radiation may corrupt data critical to the functioning of flight controls on the A320 family of aircraft.

The European Union Aviation Safety Agency issued a directive requiring operators of the A320 to address the issue.

The agency said this may cause “short-term disruption” to flight schedules.

Policy Director at the Civil Aviation Authority Tim Johnson who was in contact with UK and other airlines on Friday, said the airlines were implementing the measures speedily but that there may be some delays and customers should check their airline websites and apps over the coming days.

In the United States, American Airlines was among the carriers addressing the order.

It's begun identifying and completing the software update and expects the work on the vast majority of its A320 planes to be completed on Friday and Saturday. The fix should take about two hours for many aircraft, American said.

At least 15 JetBlue passengers were injured and taken to the hospital after the Oct. 30 incident on board the flight from Cancun, Mexico, to Newark, New Jersey. The plane was diverted to Tampa, Florida.

Airbus is registered in the Netherlands but has its main headquarters in France.

It's one of the world's biggest airplane manufacturers alongside Boeing.

The A320 is the world’s best-selling single-aisle aircraft family, Airbus' website said.
