Japan Airlines has said that it has grounded a Boeing 787 Dreamliner airplane as its staff had noticed smoke coming from the battery.
On Tuesday, ground staff noticed white smoke outside the plane and the warning lights in the cockpit indicated possible faults with the main battery and charger. On investigating they found that one battery cell was leaking.
Boeing Co said it was “aware of the 787 issue that occurred Tuesday afternoon at Narita, which appears to have involved the venting of a single battery cell. ”
The incident comes nearly a year to the day after Japan Airlines and All Nippon Airways grounded their 787 fleets after two 787 batteries overheated on two different planes in less than two weeks.
Global regulators grounded the worldwide fleet on January 16, 2013. The planes remained grounded for more than three months while Boeing redesigned the battery, charger and containment system to ensure battery fires would not put the airplane at risk. The cause of the battery problems has not been determined.
The plane which was due to depart from Tokyo Narita airport for Bangkog has been taken out of service and the 158 passengers were put aboard a separate 787.
