The FAA said it is reducing flight operations at Newark Airport due to equipment outages, staffing shortages and runway construction in order to alleviate delays and congestion.

The temporary restrictions are being imposed after repeated flight delays and cancellations. The cap will increase to 68 flights per hour in mid-June.

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.
