FAA halts flights at major East Coast airports due to fiber line cut

The United States Federal Aviation Administration (FAA) has halted flights to several busy East Coast airports amid an equipment outage, snarling more than 1,000 flights.

On Monday, the FAA issued ground stops at large commercial airports, including New York’s John F Kennedy International (JFK) and LaGuardia; Newark Liberty International in New Jersey, as well as Boston Logan and Philadelphia International Airport.

The flights were halted on the day that 130 world leaders and dozens of ministers were arriving in New York for the annual high-level meeting of the United Nations General Assembly.

US Transportation Secretary Sean Duffy said in a post on social media platform X that flights have resumed into New York’s LaGuardia and into Philadelphia, but that ground stops are still in effect at Newark, JFK, and Teterboro Airport in New Jersey. The ground stop has also been lifted in Boston.

FAA Administrator Bryan Bedford told reporters on Monday that it had “lost the primary circuit” at what is called Philadelphia TRACON, or Terminal Radar Approach Control, which controls air traffic into Philadelphia and airports across the busy northeast US airspace.

Bedford said that the backup fibre had a break and told reporters that it could take up to 13 hours to repair. He said the cut was between the city of New Brunswick, New Jersey, and Newark, New Jersey, which is home to Newark Liberty International Airport.

“An Amtrak construction crew accidentally cut into a fiber line in New Jersey which caused a telecom outage and forced FAA to pause flights in the Northeast,” Duffy said in a post on X.

At Newark alone, more than 1,000 flights had been delayed or cancelled. Throughout the US, there were nearly 4,000 delayed flights and 500 cancelled.

United Airlines said it would waive change fees for impacted travellers. Newark serves as a major hub for the airline.

“Flights that had been destined for Newark have either been held at their departure airport or diverted to alternative airports. Once the FAA outage is resolved, we will work to safely get our customers to their destinations and have issued a travel waiver to give our customers flexibility to manage their travel plans,” a representative for United Airlines said in a statement provided to Al Jazeera.

Newark has recorded the highest levels of delays and cancellations of any airport, according to FlightAware, which tracks flight disruptions in real time. As of 3pm Eastern Time in the US (19:00 GMT), 31 percent of departing flights from Newark had been cancelled, along with 29 percent of inbound flights. Meanwhile, 17 percent of departing flights from the United hub had been delayed, as had 17 percent of inbound flights.

A ground stop was also issued at Teterboro Airport in New Jersey, a private airport neighbouring New York City.
