The US aircraft maker currently occupies four bays inside the sprawling Hangar Three at Aviation Technical Services on the south end of the Paine Field campus in Everett, Washington, home to Boeing's widebody assembly operations.
Beginning mid-year Boeing will complete its takeover of Hangar Three, assuming control of five bays available to conduct modification operations, each with a specific task to prepare the 787 for handover to airline customers.
The move marks another in a continued series of industrial expansions for the 787 programme, along with its acquired suppliers and new final assembly line Charleston, South Carolina and coming Everett surge line.
The first 787 is expected to be delivered as early as July to Japan's All Nippon Airways, with as many as 20 to follow to Japan Airlines, Air India and China Southern before the end of 2011.
