The flight was Boeing's final certification test for the battery system it redesigned following smoke and fire incidents in January. Boeing Co. said the test would show the Federal Aviation Administration that the new system performs as intended "during normal and non-normal flight conditions."
The Boeing Co. unveiled what executives called a "proposed permanent solution to the 787 battery issue" Thursday night. The company’s 787 fleet has been grounded for two months because of safety concerns over the plane’s lithium-ion batteries. Two batteries in the fleet’s first 50 planes have had smoke and fire incidents.
