The Federal Aviation Administration has canceled a ground stop at Newark Liberty International Airport that was “due to equipment issues,” an FAA spokesperson told Fox News Digital.

The agency said there were equipment issues that affected some radio frequencies in the Philadelphia TRACON area that handle Newark arrivals and departures. It said it was investigating the cause.

The ground stop was in effect for about two hours, impacting inbound flights to the New Jersey airport.

During the ground stop, the FAA status website showed arrival delays averaged about 90 minutes.
