Transportation Secretary Sean Duffy says a new software update prevented a third radar outage over the last two weeks at New Jersey's busy Newark airport when a telecommunications line failed again over the weekend.

Radar screens at New Jersey's Newark Liberty International Airport went black again early Friday morning. The outage happened at 3:55 a.m. and lasted about 90 seconds, the Federal Aviation Administration said.

Newark Liberty International Airport suffered another brief air traffic control outage Friday morning, the FAA confirms.

The air traffic controllers directing planes into the Newark, New Jersey, airport lost their radar Friday morning for the second time in two weeks.

The failure was the second such incident in the past two weeks, amid continuing concerns over safety at the airport.

Radar screens that monitor Newark Liberty International Airport in New Jersey went completely black for about 90 seconds early Friday morning, according to a new report from ABC News. The outage comes after an identical problem last week when air traffic control screens for the same airport went dark for about 60-90 seconds.

Sunday's incident marks the fourth time in the past two weeks that technical problems have disrupted air traffic at Newark.

We have to fix this, because what you see in Newark will happen in other places across the country,” a top federal official said.
