Communications Failure at 22 Centers Prompts FAA to Halt U.S. Departures as a Precaution
Key Facts
The U.S. Federal Aviation Administration halted departures nationwide on November 13 after a communications problem at regional air traffic control centers, describing the move as a precautionary safety measure. Transportation Secretary Sean Duffy said the failure affected 22 centers that direct aircraft between airports, and that agency technicians were investigating it. The agency said all flights were accounted for, while incoming international flights were handled on a case-by-case basis. The halt came with no announced timetable for resuming flights, leaving airlines and travelers facing disruption to U.S. air traffic. The Associated Press said the order remained in effect until at least 11 p.m. Eastern time on Friday.
Duffy said the problem affected communications at regional control centers, which direct aircraft between airports, while technicians worked to determine its cause. Homeland Security Secretary Markwayne Mullin said the incident was a communications outage and that there were no indications of a sabotage attack at that point. The Associated Press quoted him as saying: "This was a malicious attack against us. It's just a communications outage." The FAA said flights were accounted for and incoming international flights would be handled on a case-by-case basis. Limiting the measure to departures reflects the need to treat communications as part of traffic management and aviation safety.
In terms of the operational impact, a U.S. crew on a flight from Wichita to Chicago returned the aircraft to the gate after it had remained on the runway for about an hour. The airline said rebooking would not begin for at least an hour, a direct sign that the halt disrupted passenger schedules even before a resumption time became clear. The order remained in effect until at least 11 p.m. Eastern time, according to the agency's update, while no timetable for a return to service had been announced. In a previous regional communications outage in September 2026, about 9,500 U.S. flights were delayed or canceled on Monday, Reuters reported. The September problem disrupted hundreds of flights in the Northeast, while the November failure was nationwide in scope.
Aviation safety expert Steve Arroyo said keeping aircraft on the ground prevents exposing them to the risk of losing contact in flight. The Associated Press quoted him as saying: "Aircraft have to be grounded, and not sent into the air where they risk being unable to communicate with them." The incident comes amid the first nationwide departure halt since January 2023, when a key FAA computer system failed. A nationwide halt had previously followed the September 11, 2001 attacks. These precedents show that disruptions to U.S. aviation systems can lead to broad restrictions when they affect controllers' ability to track flights.
The failure refocused attention on a program to modernize air traffic control technology. Congress had approved $12.5 billion for the project in the year before the Associated Press report, while Duffy said completing the work would require an additional $30 billion, and the White House had begun pressing Congress to approve it. In September 2026, FAA Administrator Bryan Bedford estimated the total cost of the modernization at $27 billion and said Congress needed to approve an additional $10.5 billion. He also said replacing old copper wiring with fiber was expected to be completed by September 2027, but would not by itself be enough to prevent future outages. Authorities are examining whether the November failure was linked to the nationwide rollout of a new artificial intelligence system; Mullin said the system operates from a site near Washington and sends recommendations only to control centers, with no flight resumption timetable announced at the time of the agency's report.
