WASHINGTON (AP) -- Boeing is getting permission for test flights of its 787 as it tries to fix battery problems that have kept the plane grounded.
The Federal Aviation Administration says the test flights will have restrictions, including pre-flight testing and inspections, and in-flight monitoring. The tests are limited to airspace over unpopulated areas.
Boeing says the tests will happen on one of the six airplanes it used for testing before the 787 was certified by the FAA in late 2011.
The planes still can't be used for passenger flights until the FAA is satisfied that the battery problem is fixed. The grounding order issued on Jan. 16 meant that Boeing even needed FAA permission to fly an empty 787 from Texas to Washington state on Thursday after it had been painted.
