US aviation safety regulators will allow fewer flights at Newark airport after technology outages and a staffing crunch fueled a surge in delays and cancellations in recent weeks.

The interim rule will cap the number of arrivals and departures at Newark Liberty International Airport at 28 apiece per hour. That’s in line with the limits imposed after about half a dozen controllers went on a 45-day trauma leave following the first outage on April 28.

The Federal Aviation Administration said Monday the facility that handles Newark air traffic on Monday lost radio frequencies for approximately two seconds, the latest in a series of telecom issues.The incident occurred around 11:35 a.
