The FAA has ordered an emergency halt to all departures across the country, citing unspecified safety concerns
The Federal Aviation Administration (FAA) has ordered a rare nationwide ground stop for all departing flights across the United States, citing unspecified safety concerns.
The emergency directive took effect at 3:54pm Eastern Time on Friday, with all departing aircraft instructed to remain on the ground until further notice.
According to the advisory, international flights arriving in the US are being handled on a case-by-case basis. The FAA has not specified how long the restrictions will remain in effect.
US Transportation Secretary Sean Duffy said the nationwide ground stop was prompted by a “communication issue impacting all Air Route Traffic Control Centers.”
“FAA technicians are investigating the issue. We will provide immediate updates as we have them,” he wrote on X.
Preliminary reports suggest the disruption was not caused by a cyberattack, CNN reported, citing two law enforcement officials.
Homeland Security Secretary Markwayne Mullin said the grounding was caused by a “telecommunications outage,” which authorities do not believe was the result of foul play.
The National Weather Service also reported nationwide internet and communications problems, warning that some weather information on its websites could be unavailable or outdated. The agency said technicians were working to restore services.
The last nationwide ground stop was ordered in January 2023 following a failure of the system that provides safety notices to pilots. The previous such shutdown occurred in the immediate aftermath of the September 11, 2001 terrorist attacks.
The outage came just days after the FAA announced the nationwide rollout of SMART, a new AI-powered system designed to optimize flight routes and reduce delays. The technology was deployed across all 22 regional air traffic control centers, although authorities have not established whether it played any role in Friday’s disruption.
Similar technical failures have disrupted air travel worldwide this year. In September, a communications outage halted flights at major airports in the northeastern US, while a software malfunction caused widespread flight cancellations across Britain. Greece temporarily closed its airspace in January, and Italy halved its air traffic capacity following a technical failure in October.
