FAA halts flights to major US East Coast airports amid outage
The Federal Aviation Administration imposed ground stops at several major East Coast airports after an equipment outage tied to a fiber cut disrupted radar systems that manage Northeast airspace. The interruption affected airports including JFK, LaGuardia, Newark, Boston Logan, Philadelphia and Teterboro, causing widespread delays and cancellations during the United Nations General Assembly arrivals.
Why It Matters
The outage disrupted busy northeastern U.S. airspace on a day when international leaders were arriving in New York, producing cascading impacts across airlines and hubs and highlighting vulnerability of critical air-traffic infrastructure to local telecom disruptions.
Key Facts
- Affected airports: JFK, LaGuardia, Newark Liberty, Boston Logan, Philadelphia International, Teterboro
- Cause: Primary circuit loss at Philadelphia TRACON; backup fiber line cut
- Reported breaker: Amtrak construction crew accidentally cut fiber between New Brunswick, NJ and Newark, NJ
- Repair time estimate: FAA said repairs could take up to 13 hours
- Nationwide disruption totals: Nearly 4,000 delayed flights and about 500 cancelled
The U.S. Federal Aviation Administration issued ground stops at multiple major East Coast airports after losing critical communications equipment that supports approach control for the region. The outage affected airspace served by Philadelphia TRACON and led to pauses in arrivals and operations at John F. Kennedy International, LaGuardia, Newark Liberty, Boston Logan, Philadelphia International, and nearby Teterboro airport.
FAA Administrator Bryan Bedford said the agency lost the primary circuit at Philadelphia TRACON and that the backup fiber had been severed. Officials said the fiber break occurred between New Brunswick and Newark, New Jersey. Transportation Secretary Sean Duffy posted that an Amtrak construction crew accidentally cut the line, and the FAA estimated repairs could take up to 13 hours.
The interruption produced heavy disruption at Newark, where more than 1,000 flights were delayed or cancelled and the airport recorded the highest levels of delays and cancellations nationally. As of 3:00 p.m. Eastern, FlightAware data showed roughly 31% of Newark's departing flights and 29% of inbound flights were cancelled, and about 17% of both departing and inbound flights were delayed. Across the United States, nearly 4,000 flights were delayed and around 500 were cancelled.
By midafternoon, some ground stops had been lifted: flights into LaGuardia and Philadelphia resumed, and the ground stop in Boston was cleared, while Newark, JFK and Teterboro remained under restriction. United Airlines, which uses Newark as a major hub, said it would waive change fees for passengers affected by the disruption and that some flights destined for Newark were held at departure or diverted to alternate airports.
The outage occurred on a day when more than 130 world leaders and numerous ministers were arriving in New York for the United Nations General Assembly, compounding logistical challenges for international and domestic travelers. FAA and transportation officials said they were working on repairs and on safely resuming normal operations across the Northeast.
