Another incident involving the main lithium-ion battery in a Japan Airlines Boeing 787 just before its scheduled departure from Tokyo on Tuesday has prompted an investigation by the Japan Civil Aviation Bureau, with help from the U.S. National Transportation Safety Board, raising new questions about the integrity of a system redesign devised to mitigate the possibility of fire propagation. Battery overheating in airplanes operated by JAL and fellow Japanese airline ANA led to a worldwide grounding of the 787 fleet early last year, forcing Boeing to develop modifications to the charging system and install containment and venting systems.
