GS Yuasa Corp., the battery supplier to Boeing Co. 787 planes that are being grounded, said it may take months to complete its investigation into what caused an emergency landing of an All Nippon Airways Co. Dreamliner.
The company needs to find out whether the emergency landing in Japan yesterday was caused by an issue with the battery or the entire electrical system is at fault, its spokesman Hiroharu Nakano said by phone today. The plane’s electrical system needs to be dismantled for the full investigation, which may take months, he said.
