Investigators from the NTSB arrived at Newark Liberty International Airport on Monday after a near catastrophe over the weekend.
Sunday's incident marks the fourth time in the past two weeks that technical problems have disrupted air traffic at Newark.
Air traffic control problems continued at Newark Liberty International Airport on Sunday morning after an equipment issue prompted the Federal Aviation Administration to order a 45-minute ground stop at the New Jersey airport, officials said.
