(TOKYO) -- An initial investigation into one of the Boeing 787 Dreamliner incidents has answered at least one question.
Japan’s Transport Safety Board says the lithium-ion battery that burned mid-flight aboard an All Nippon Airways Dreamliner, prompting an emergency landing last week, wasn't overcharged.
But the battery has not been ruled out as the cause of the fire. It continues to be the main focus of the Transport Safety Board's investigation with the National Transportation Safety Board and Federal Aviation Administration.
Officials have already conducted a CT scan in Japan and plan to disassemble the burned battery so they can analyze it piece by piece.
Meanwhile, the probe into the Japan Airlines Dreamliner that leaked fuel earlier this month has now shifted to the U.K., where Japanese inspectors are investigating the company that manufactures the valve actuator.
