Japan probe finds lithium ion battery on Boeing 787 not overcharged
TOKYO (AP) - Japan's transport safety agency says a lithium ion battery on a Boeing 787 that overheated during an All Nippon Airways flight earlier this month, prompting an emergency landing, was not overcharged.
Japan Transport Safety Board chairman Norihiro Goto told reporters on Wednesday the flight's data recorder showed the battery was not overcharged.
That contradicts an earlier finding by the agency as it investigates with the U.S. Federal Aviation Administration.
Investigators from both sides are probing the maker of the battery, GS Yuasa, and are examining it using CAT scans at a facility of Japan's aerospace agency.
