NEWARK/WASHINGTON - A facility that guides air traffic in and out of Newark airport suffered a new 90-second communications outage early on May 9, the second in two weeks that prompted an air traffic controller to complain “Scopes just went black again” to a nearby FedEx flight.

The Federal Aviation Administration said the telecommunications outage impacted communications and radar displays at Philadelphia Terminal Radar Approach Control that guides aircraft in and out of Newark Liberty around 3.55am Eastern time on May 9 (3.55pm in Singapore) and lasted approximately 90 seconds.

FedEx did not immediately comment.

The latest incident highlights the air traffic control network’s ageing infrastructure and comes a day after Transportation Secretary Sean Duffy proposed spending billions of dollars to fix it over the next three to four years.

White House spokeswoman Karoline Leavitt said “there was a glitch in the system” caused by the same telecom issue that caused the prior incident. She said the goal is to address the technical issue later on May 9 “to prevent further issues”

The FAA said on May 7 it was taking immediate steps to address ongoing problems that have disrupted hundreds of flights at Newark since April 28 especially from United Airlines , the largest carrier at the airport located just outside New York City.

United said on May 9 the FAA outage impacted its Newark operation but did not elaborate. It has sharply cut flights and wants the FAA to impose new limitations on Newark flights to address ongoing delays.

“Decades of failing to properly invest in the system has prevented good-faith efforts to make technology upgrades and bolster the staffing of our nation’s hard-working air traffic controllers,” United CEO Scott Kirby said in a Fox News op-ed on May 9.

The FAA said it is increasing air traffic controller staffing, adding three new, high-bandwidth telecommunications connections and deploying a temporary ...
