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 New Jersey airport, which has faced radar problems and major delays, is scrambling to bring in more air traffic controllers and complete construction.

At one point, the FAA had targeted 77 total arrivals and departures at Newark each hour, but at the start of construction on April 15 they requested airlines cut that down to 70 total during the day and 62 during specific hours in the late afternoons and evenings.
