Dreamliner battery probe rules out sudden voltage surge
TOKYO (AFP) - Officials probing the emergency landing of a Boeing Dreamliner said today they will dismantle its battery pack, after the investigation found no evidence of a sudden surge in voltage.
A fire risk from overheating powerpacks emerged as a major concern after pilots were forced to land the domestic All Nippon Airways (ANA) flight in western Japan on Jan 16 due to smoke thought to be linked to the plane's battery.
Investigators later released a picture showing the blackened remains of the battery in the ANA plane.
But they said today there were no signs of a battery fire, while data gleaned from the flight's digital data recorder showed the powerpack did not suffer a rapid surge in voltage.
