Japan space agency tests Dreamliner battery

PTI Tokyo | Updated on March 12, 2018

The charred lithium-ion battery from a troubled Boeing Dreamliner was taken to Japan’s space agency on Tuesday, as investigators tried to find out what caused it to overheat on a domestic flight.

Scientists at the Japan Aerospace Exploration Agency will run scans on the battery to see if they can discover what led it to smoulder, sparking the worldwide grounding of the next-generation aircraft, said Transport Minister Akihiro Ota.

“A CT scan will be performed at the facility” today and tomorrow, Ota told a regular press briefing.

“As for the safety investigation into the cause (of the problem), that will be done in conjunction with the NTSB and the FAA,” he said, referring to the US National Transportation Safety Board and Federal Aviation Administration.

Boeing’s cutting-edge planes suffered a series of problems earlier this month, prompting a global alert from the FAA that has seen all 50 operational Dreamliners parked up since last week.

The risk of fire from overheating powerpacks emerged as a major concern after pilots were forced to land a domestic All Nippon Airways flight on January 16 due to smoke apparently linked to them.

Investigators on Friday released a picture showing the blackened remains of the battery in the ANA plane.

They are also inspecting the aircraft’s black box which contains data from the flight that may help to assess how the battery was affected.

Investigators have inspected the offices of GS Yuasa, which manufactures the batteries for the Dreamliner’s advanced electronics systems.

They have stressed that the probe does not mean authorities think Kyoto-based GS Yuasa was to blame for the problems.

But shares in GS Yuasa, whose batteries have been pressed into service in hybrid and electric vehicles, dropped on the Tokyo Stock Exchange today.

The firm, which reportedly has a contract to supply batteries to the International Space Station, is one of many contractors in a complex global chain that led to three years of delays before Boeing delivered its first 787 to ANA in 2011.

US investigators probing a fire on a Japan Airlines 787 after it landed in Boston on January 7 ruled out the overcharging of the battery as the cause.

But the NTSB was still testing the charger and components linked to the battery.
