Battery problem on 787 flight to Helsinki

Japan Airlines reports Dreamliner battery glitch



A problem with the same kind of battery that caught fire in Boston in January, leading to the grounding of the world’s 787 fleet for three months, has struck again – this time on a Japan Airlines flight from Helsinki to Tokyo.

The JAL website said on Sunday that a cockpit indicator on Friday’s flight 414 showed a problem with the battery linked to the aircraft’s auxiliary power unit. However, the battery did not overheat or give off smoke.

“The voltage and electrical current were within normal range and there was no effect on the remainder of the flight,” the website added.

Each 787 has two big lithium-ion batteries that provide backup power to aircraft systems. Inspections of the battery are continuing.
