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.

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.

The blackout included losing radar for about 90 seconds at Newark Terminal Radar Approach Control at 3:55 a.m. local time, a source with knowledge of the incident tells CNN.

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

The city of Newark will install radar detection equipment at a downtown intersection later this year to boost traffic efficiency and safety.

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