Japan's investigation of a battery that was smoking on a Boeing 787 flight there last month has not yet determined if the incident started in the same way as a fire on another 787 in Boston, a Japanese official said Friday.
Akinobu Yokoyama, a spokesman for Japan's Transport Safety Board, said it was still not clear whether a short-circuit or other malfunction occurred within one or more of the eight cells in the new lithium-ion battery.
His comments in an interview came a day after Deborah Hersman, the chairwoman of the National Transportation Safety Board, said the problems on the Boston jet seemed to have originated in the battery. She said one of the cells had a short-circuit that created a "thermal runaway" as it cascaded through the rest of the cells, heating the battery to 500 degrees.
