United Continental pilots flew the carrier's first Boeing 787 to Texas for installation of a battery fix. Boeing said the update will take approximately five days to complete. United plans to resume domestic flights of the 787 on May 31.
Boeing may launch a 787 certification test flight today, according to a government source, but the company would not confirm the flight plan. "As a matter of long-standing policy Boeing does not provide advance notice of flight test activities until we have filed flight test plans," Boeing spokesman Marc Birtel said.
United Airlines has pushed back the launch of its Denver-to-Tokyo service until 10 June. United plans to use the Boeing 787 Dreamliner for the route, which was originally scheduled to begin on 31 March. Last week, Boeing CEO Jim McNerney said the company was "very close" to gaining approval of the 787 for passenger flights.
On Monday, Boeing conducted a second test flight of its 787 Dreamliner. The flight lasted an hour and 29 minutes, and included 11 test-flight employees and two pilots. Boeing says it will analyze the data from the flight.
