Rare nationwide ground stop ordered at airports over communication issues: FAA

It's the second time since Sept. 11, 2001, that such a stop has been ordered.

The Federal Aviation Administration ordered a nationwide ground stop Friday for all airports due a communication issue affecting air traffic control.

The agency's alert said the stop was "due to extraordinary circumstances and for reasons of safety."

Transportation Secretary Sean Duffy said in an X statement a short while later that the stop was "due a communication issue impacting all Air Route Traffic Control Centers."

"FAA technicians are investigating the issue," he said in an X post.

This is the second time since Sept. 11, 2001. that the FAA has ordered a nationwide ground stop. The last time was in 2023, when the FAA NOTAM system went down and pilots could not get their pre-departure paperwork.

Air Route Traffic Control Centers are responsible for all flights above 18,000 feet. There are 22 of those centers in the U.S.

Earlier in the afternoon, the FAA issued a ground stop at both Chicago's O'Hare and Midway airports due to equipment outage.
