Tokyo: The joint US and Japanese investigation into the Boeing 787’s battery problems has moved from the battery-maker to the manufacturer of a monitoring system.
Transport ministry official Shigeru Takano said today the probe into battery-maker GS Yuasa was over for now as no evidence was found it was the source of the problem.[caption id=“attachment_604292” align=“alignleft” width=“380”] Battery problems. Reuters[/caption]
Ministry officials said they are inspecting Kanto Aircraft Instrument Co. later in the day as part of the ongoing investigation.
It makes a system that monitors voltage, charging and temperature of the lithium-ion batteries.
All Boeing 787s are grounded after one of the jets made an emergency landing in Japan earlier this month when its main battery overheated.
Earlier a battery in another 787 caught fire while parked at Boston’s Logan International Airport.
