Boeing 787 could fly in weeks

Boeing said a proposed redesign of the 787 Dreamliner’s battery systems could allow commercial flights to restart within weeks after two incidents had caused the plane to be grounded for two months.

The battery now has extra safety measures, including a new enclosure and adjustments to the charger, Boeing said in a statement in Tokyo Friday. The device will undergo more rigorous tests, and its manufacturer, GS Yuasa Corp., had fully cooperated in the process, Ray Conner, head of Boeing’s commercial planes division, said at the event.
