ATLANTA: U.S. regulators on Friday approved a revamped battery system for Boeing Co's 787 Dreamliner, a crucial step in returning the high-tech jet to service after it was grounded in January because the plane's lithium-ion batteries overheated.
The Federal Aviation Administration approval of design changes allows Boeing to immediately begin making repairs to the fleet of 50 planes owned by airlines around the world. Other global regulators must approve Boeing's design for repairs outside the United States, but were expected to act quickly now that FAA had given its blessing.
