United Airlines has started construction of a new 90,000 square ft (27,432 square m) widebody maintenance hangar at Newark Liberty International Airport.
The airline expects to complete the nearly $25 million hangar by the end of the year, which will provide a space to maintain larger aircraft like the Boeing 787.
"This state-of-the-art facility will be the workplace for more than 700 United aviation maintenance technicians," said Joe Ferreira, United's vice president of line maintenance in a statement. "From this hangar, they will work together to ensure the safety and reliability of United's fleet and the comfort and convenience of our customers."
United accepted a 25-year lease on the three-acre site where the new facility will be built.
The mainline carrier operates more than 400 flights per day out of Newark and employs about 13,000 people at the hub. In May, the airline will add service to Edmonton from the airport and will end flights from Newark to Philadelpha on 9 April.
United also plans to complete a 125,000 square ft (11,612 sq m), nearly $45 million hangar at Washington Dulles Airport by the end of the year, which is capable of housing an Airbus A350-sized aircraft next to a Boeing 767-300 simultaneously. The carrier has additional maintenance facilities in Chicago, Denver, Houston, San Francisco and Los Angeles.
