Boeing 787 batteries passed first inspections this week as US and Japanese officials came up with few answers in their cursory examinations of the Boeing 787's battery fires. The company's outsourcing strategy and a weak permitting process may have contributed to the Boeing 787's glitches.
Japan transport ministry official Shigeru Takano said Monday the government had ended its on-site investigation of GS Yuasa, the Dreamliner's batterymaker. Having found "no major quality or technical problem," ministry officials said they would shift the focus of their probe onto Kanagawa Prefecture-based Kanto Aircraft Instrument Co., which makes the system that monitors the lithium-ion batteries.
