787: fire origin determined ?... The U.S. Agency Transportation Safety Board ( N.T.S.B. ) is progressing in its investigation. Indeed, they know now the origin of the outbreak of fire in one of the lithium-ion batteries of a Japan Airlines 787 on January 7... We now know a little more about the origin of the outbreak of fire in one of the lithium-ion batteries of a Japan Airlines 787 on January 7. The batteries in question are powered by eight 4-volt cells, and it was one of these that caused the uncontrolled overheating. And the U.S. N.T.S.B. ( National Transportation Safety Board ), states that fire will break out if the temperature inside the battery exceeds 260 ° Celsius (500 ° F). To date, there are no explanations for the causes of this short-circuit, but investigators are now leaning towards the data relating to the certification of the 787 provided by Boeing, and approved by the U.S. civil aviation authority, the F.A.A.. During the certification process, Boeing assessed the likelihood of smoke coming from a battery to 1 in 10 million flight hours; however, two such incidents were reported from batteries with less than 100,000 flight hours. The investigation could take several more weeks; a new progress report from the N.T.S.B. is expected within 30 days. As for the 787, it has been authorized by the F.A.A., to take to the air again, without passengers, to carry out new flight tests so that the causes of the fires can be determined.
