Transportation Secretary Sean Duffy stated on Sunday that the Federal Aviation Administration must move away from its legacy telecommunications infrastructure. This declaration followed a significant disruption on Friday, when officials attributed a nationwide ground stop to overloaded routers. The incident caused thousands of flight cancellations and left many travelers stranded at airports across the country at the beginning of the weekend.
Duffy emphasized that the necessary work has been neglected for decades because of its complexity. He noted that the FAA is currently investigating the specific causes of the failure. The investigation focuses on why a maintenance installation in El Dorado, Arkansas, began broadcasting data unexpectedly. Officials are also examining a secondary issue at a facility in Amarillo, Texas, where similar work had been performed weeks prior.
The telecommunications contractor, L3Harris Technologies, performed maintenance updates at a remote facility to replace aging copper communication lines with fiber optic connections. During the process, a router began flooding other units, which overloaded the system. Duffy confirmed that the FAA, L3Harris, and the FBI are on site to analyze the root cause. He promised to inform the public once they determine if the problem stemmed from the installation or the router itself.
The secretary explained that the specific line in El Dorado was an old copper wire that had become unusable. The telecom provider forced the update to fiber, and the network flooding occurred immediately after the routers were brought in. Duffy described this as part of routine maintenance on a very old architecture, noting that such work is typically done overnight at large facilities. However, for remote locations, daytime work is standard because historical risk has been low.
Despite the Friday incident, Duffy maintained that the work was done appropriately and that similar procedures have been performed thousands of times without issue. He stressed that the current system should be built brand new, pointing out that institutions and companies worldwide have already switched to digital and fiber. He noted that over 70 percent of copper lines have been replaced without incident, including nearly 470 radios and new electronic flight strips.
Duffy reiterated his request for $50 billion from Congress to overhaul the telecom network. He acknowledged that the FAA received funds under the One Big Beautiful Bill but stated that Congress specified how that money could be spent. He said the allocated funds are ready to be deployed by the end of the president's tenure, but he lacks the specific funding needed for a new telecom system and new software, which are critical and historically underinvested components.
The secretary argued that the FAA is finally using taxpayer money to build infrastructure and urged Congress to finish the job to prevent future disruptions. President Trump also weighed in on Sunday, posting on Truth Social that much of the current air control system is 50 years old. He urged Congress to approve the necessary funding so the work can be completed all at once rather than in small increments.
Rep. Jim Himes, a Democrat from Connecticut, offered a different perspective during a Sunday appearance on Face the Nation. He argued that this is not a problem of congressional funding but rather a prioritization issue. Himes suggested that the FAA should spend the existing funds from the One Big Beautiful Bill before requesting additional money from Congress.
Regarding the ongoing effects of the Friday ground stop, Duffy said there are some delays in the airspace. However, he projected that operations should be running at full capacity by the end of the day and into the following day. He explained that it takes time for airlines to reposition crews and aircraft after such a significant disruption, but the system is well on its way to recovery.
