A Boeing 787 Dreamliner operated by Japan Airlines, flying from Helsinki to Tokyo, experienced a battery-related incident on Sunday, the same kind of problem that caused the global grounding of the fleet last January. This is the first time there was a battery-related issue since the systems were upgraded in April and May and the planes were allowed back in the air.
According to the JAL website, Flight 414’s cockpit indicator flashed a warning that there was an issue with the lithium-ion battery that gives power to the plane’s auxiliary unit. When they determined that there was no damage to any of the equipment and that there was no problem with the electrical current or voltage in the auxiliary power system, they allowed the flight to proceed and it landed in Tokyo early Sunday morning without incident. Maintenance crew continued the inspection of the battery and they did not find any physical problem, so there is also the possibility that the defect is in the warning system itself and not the battery.
While it was only a minor glitch, airlines are very particular when it comes to problems with the state-of-the-art Dreamliner since the worldwide grounding earlier this year. JAL in particular tries to respond to the public’s concerns and reports about these incidents on their website. Boeing officials have not released a statement yet and referred questions back to JAL.
