Airlines and US aviation officials plan to meet on further flight cutbacks at Newark airport following multiple breakdowns in radar systems, according to people familiar with the matter.

Air traffic controllers at Newark Liberty International Airport faced equipment outages for the second time in a month early Friday, the FAA said.

A deadly midair collision in January between a military helicopter and a commercial airliner, and several crashes since, have prompted officials to focus on fixing the nation’s outdated air traffic control system and hiring more controllers.
