Battery problem grounds another Boeing 787

But Boeing says its design changes are working

Japan Airlines has grounded one of its fleet of Boeing 787 Dreamliners at Tokyo’s Narita Airport after a battery cell began leaking and white smoke was seen outside the plane.

The incident comes a full year after all 787s around the world were temporarily grounded by regulators. Now there are further concerns about the safety and reliability of the aircraft type. Yet Boeing says the design changes it has made are working as planned.

Boeing 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 issue occurred during scheduled maintenance activities with no passengers on board.”

It added: “The improvements made to the 787 battery system last year appear to have worked as designed.”

Japan Airlines revealed the incident early on Wednesday.
