Japan investigator points to excessive Boeing 787 battery problem
(AP) A Japanese transport ministry investigator says the burned insides of a battery in the Boeing 787 at the center of a worldwide grounding of the aircraft indicate it operated at a voltage above its design limit.
The All Nippon Airways plane made an emergency landing Wednesday morning in western Japan after its pilots smelled something burning and received a cockpit warning of battery problems. Nearly all 50 of the 787s in use around the world have since been grounded.
Photos provided by the Japan Transport Safety Board of the lithium ion battery that was located beneath the 787's cockpit show a blackened mass of wires and other components within a distorted blue casing.
The investigator says the burned insides appear similar to the battery in a Japan Airlines 787 that caught fire Jan. 7 while the jet was parked at Boston's Logan International Airport, suggesting a common cause.
