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.

Transportation Secretary Sean Duffy plans to reduce the number of flights in and out of Newark Liberty International Airport for the "next several weeks."

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 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.

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

Passengers traveling in and out of Newark at the end of the week shouldn't expect smooth sailing. Here's the latest at the New Jersey airport.

A technical outage in Philadelphia last week terrified air traffic controllers and stranded passengers. As the summer travel season looms, the F.A.A. is racing to address the problems.
