Japan Airlines is investigating the battery on a Boeing (BA) 787 Dreamliner after detecting smoke during pre-flight maintenance at Tokyo's Narita airport, the first sign of a possible failure since the units were redesigned last year.

Boeing says the incident "appears to have involved the venting of a single battery cell," and "the improvements made to the 787 battery system last year appear to have worked as designed."

BA shares fell 0.5%, paring an intraday drop of as much as 2.1% that followed the disclosure of the incident; the small decline reflected confidence that the battery "fix worked,” according to a Jefferies aerospace analyst.
