Design flaws led to 2013 lithium-ion battery fire in Boeing 787: U.S. NTSB

Design flaws led to 2013 lithium-ion battery fire in Boeing 787: U.S. NTSB
WASHINGTON Tue Dec 2, 2014 7:28am EST
(Reuters) - A lithium-ion battery that caught fire aboard a parked Boeing 787 in 2013 in Boston had design flaws and it should not have been certified by the U.S. Federal Aviation Administration, U.S. accident investigators said on Monday.
The National Transportation Safety Board said the battery, manufactured by GS Yuasa Corp, experienced an internal short circuit that led to thermal runaway of the cell. This condition caused flammable materials to be ejected outside the battery's case and resulted in a small fire, the NTSB said in its report on the incident.
The agency said its investigators found a number of design and manufacturing concerns that could have led to the short circuiting, including the presence of foreign debris and an inspection process that could not reliably detect defects.
"We are looking at the report from the NTSB, and until we have examined its findings we don't wish to comment," a spokeswoman for GS Yuasa said. The Japanese battery maker's shares dipped as much as 3.2 percent in Tokyo after the NTSB released its findings.
