The Federal Aviation Administration ordered a nationwide ground stop Friday afternoon following a communications issue, affecting all Air Route Traffic Control Centers, including in Michigan, Transportation Secretary Sean Duffy said.
FAA technicians were investigating the problem, Duffy said in a statement posted on X.
"We will provide immediate updates as we have them," he wrote.
The FAA's nationwide advisory directed all departing traffic to remain grounded until further notice, citing "extraordinary circumstances" and safety concerns. Inbound international flights would be handled on a case-by-case basis.
The national advisory was issued at 3:54 p.m. Eastern time.
Travelers should check their airlines for flight-specific updates.
