An air traffic control facility that guides planes at Newark Liberty International Airport in New Jersey had a brief radar outage Friday morning, the latest technological disruption at one of the nation’s busiest airports.

The Federal Aviation Administration said that the outage, which affected communications and radar displays at a facility in Philadelphia, occurred just before 4 a.m. and lasted about 90 seconds.

“Everything went back online after the brief outage and there was no operational impact,” she said. Federal transportation officials “are working to address this technical issue tonight, to prevent further outages,” Leavitt said. Officials are also planning to install new fiber optic cables from Newark airport to Philadelphia, she said. The goal is to have the system fully upgraded by the summer, she said.

An air traffic controller directing traffic at Newark early Friday mentioned the latest outage to the pilot of FedEx Flight 1989 when it occurred, according to a publicly available recording of air traffic control communications with pilots.
