Japanese and US investigators began a probe Monday into the maker of the lithium ion batteries used in Boeing's grounded 787 jets.
Tsutomu Nishijima, a spokesman for GS Yuasa, the battery manufacturer, said investigators visited the company's headquarters in Kyoto, Japan and that Yuasa was cooperating with the probe.
All 50 of the 787 Dreamliners that Boeing has delivered to airlines were grounded after an overheated battery forced the emergency landing of an All Nippon Airways 787 flight last week. Boeing has halted deliveries of new planes until it can address the problems. Monday's investigation involved an introductory meeting and factory tour, with deeper studies into product quality and other issues to follow as the probe continues, said Tatsuyuki Shimazu, the chief air worthiness engineer at the civil aviation bureau's safety department.
