On Monday, September 21, 2026, a Verizon fiber-optic cable was severed around 9:45 a.m. by construction contractors working on a rail project in New Jersey, triggering a major communications failure at the Federal Aviation Administration’s Philadelphia TRACON facility. Philadelphia TRACON oversees radar approach control and air traffic operations for five major Northeast airports: Newark Liberty International, Philadelphia International, LaGuardia, John F. Kennedy International, and Teterboro.
The cable cut disabled both the primary and backup communications circuits at Philadelphia TRACON, forcing the FAA to impose ground stops and airspace restrictions starting in the Philadelphia and New Jersey vicinity and extending to
New York City airports. The outage severely impacted flight operations, causing delays of up to 150 minutes and widespread cancellations.
Newark and JFK Account for Most Cancellations
Newark Liberty International Airport experienced over 600 flight cancellations by 6 p.m. on the same day, with more than 200 cancellations and 400 delays reported at Philadelphia International Airport. Nearly 100 flights were diverted to other U.S. airports due to the communications outage affecting arrivals and departures at Newark and Philadelphia. Airlines such as United and American responded by waiving change fees and offering accommodations to affected passengers, with United particularly impacted due to Newark being its busiest international hub.
Severed Fiber Cable Causes Dual Circuit Failures at Philadelphia TRACON
The outage originated when contractors working about 10 feet away from utility markings on the New Brunswick to North Brunswick rail project accidentally cut a Verizon fiber-optic cable. The severed cable disabled both the primary FAA communications circuit and its backup, which was already damaged prior to the incident. FAA Administrator Bryan Bedford noted that the affected communications infrastructure relies on 50-year-old data architecture. Philadelphia TRACON has experienced previous communication and radio outages that disrupted flight traffic.
FAA, Verizon, and NJ Transit Respond to Incident
Verizon stated its cables were properly placed and attributed responsibility for the damage to the construction contractors. “Construction contractors working in the area
dug up and cut our cable,” a Verizon spokesperson said, emphasizing the contractors’ responsibility for locating markings and carrying out the work. NJ Transit is investigating the incident alongside Verizon and the contractor. A NJ Transit spokesperson said, “We will continue to work closely with Verizon and the contractor as the circumstances surrounding the incident are being investigated.”
Transportation Secretary Sean Duffy confirmed the fiber cable repairs were completed by Monday evening and that operations were returning to normal, but cautioned, “It will take some time to clear all existing delays.” He added, “This incident… prevent disruptions like this in
the future.” FAA Administrator Bedford highlighted the need to replace the outdated network architecture with a modern federal enterprise system, stating, “The FAA wants to replace that architecture… and we need budget for that.”
Travelers Face Delays Amid Recovery from Outage
Flight disruptions caused by the outage affected thousands of passengers across the Northeast region, leading to ground stops and delays at Newark, JFK, LaGuardia, Philadelphia, and Teterboro airports. Airlines continue to manage crew repositioning and schedule adjustments. An air traffic controller at Philadelphia International remarked on the difficulty, stating, “Yeah, man, nothing works… People are getting out, but it’s slow going.”
Travelers flying through the affected
airports should refer to their airlines for updated flight statuses as residual delays and cancellations persist despite the restored communications infrastructure.
FAA Modernization Highlighted Amid UN General Assembly Arrival
The communications outage occurred the same day the FAA and the Department of Transportation unveiled the Strategic Management of Airspace, Routes and Trajectories (SMART) system, an AI-supported platform designed to optimize air traffic management. Transportation Secretary Duffy and FAA Administrator Bedford confirmed that the SMART system is unrelated to the outage, which exposed the vulnerabilities in the FAA’s underlying communications technology.
The incident coincided with the arrival of international delegations to New York City for the United Nations General
Assembly, affecting flight schedules for diplomats including the Canadian Prime Minister. The FAA outage has renewed calls for urgent modernization of the nation’s aging air traffic control infrastructure.
