According to the Federal Aviation Administration, the ground station at Newark Liberty International Airport was cancelled Sunday, the latest release in a series of issues that have plagued the airport in the past few weeks.

"The FAA briefly slowed the speed of planes entering and leaving the airport while we ensured job layoffs. Operations returned to normal," the FAA said in a statement on X.

The FAA did not elaborate on why the ground stop was released at 8:15 a.m. local time, but said there was a telecommunications problem in Tracon Creation C in Philadelphia, a traffic control facility that guides flights in and out of Newark. The facility had previously had a power outage on April 28, a catalyst for a major delay at Travel Hub.

Newark Airport said the ground stop was caused by a “faA equipment outage” and has since been cancelled.

According to the National Air Traffic Controllers Association (NATCA), during the power outage last month, air traffic controllers in Tracon Area C lost communication with aircraft going to and from the airport, making them unable to see, hear or talk to them.

It is unclear what causes communication losses or how long the air traffic controllers have lost their planes.

According to a union representing approximately 20,000 aviation professionals, the activity led to air traffic controllers filing leave under the Federal Lossectal's Reskation Act, which covers federal employees who have been injured or experienced traumatic events at work.

The delays and cancellations of flights in and out of Newark Airport have been constant since the incident. Airlines, including Manchester United, had to cancel hundreds of flights, and dozens of people had been transferred to other airports.

Many problems have caused interference, including understaffing, construction and several instances of technical equipment failures.

Transportation Secretary Sean Duffy said in an exclusive interview with Media Media that he was concerned about the entire U.S. airspace following the recent power outage in Newark, adding that both telecommunications problems and faults in the software should be blamed.

"Now, I think the lights are flashing, the sirens are turning, and they say, 'Listen, we have to fix this." "Because what you're seeing in Newark will happen elsewhere in the country. Must be resolved. ”

Duffy said he thinks they will be "up and running for a short time."

According to Flightaware.com, 85 flights to and from Newark were postponed, with more than 80 cancelled as of Sunday morning.
