Japan Airlines Co. is investigating what caused a battery on a Boeing Co. 787 Dreamliner to smoke during preflight maintenance, a year after a fire on one of the carrier’s jets helped spur the grounding of the global fleet.
Mechanics found that one of eight battery cells had vented liquid through a safety valve yesterday, while the others were intact, said Seiji Takaramoto, a JAL spokesman. Instruments in the cockpit showed a possible fault in a main battery and a main battery charger, he said.
