Ground Stops and Delays
According to NBC News reporting published on September 21, 2026, the Federal Aviation Administration ordered ground stops at Newark Liberty, Teterboro, and Philadelphia airports on Monday due to a technology breakdown at Philadelphia’s Terminal Radar Approach Control facility. The disruption began with ground stops at Philadelphia and Teterboro shortly before a Newark ground stop was initiated just after 10 a.m. [1]
Impact and System Status
The FAA reported that the issue involved frequencies at the Philadelphia TRACON facility, resulting in departure delays reaching up to 150 minutes at Newark and Philadelphia. While the agency paused flights in one of the country's heaviest air travel corridors, it did not specify a timeline for when the affected systems would be fully restored. [1]
