Japan Air grounds Boeing 787 after battery problem
He said it appeared the containment system worked. "It limited the problem to one faulty cell. It contained the problem and vented the fumes outside the airplane, as designed," he said, basing his comments on Japan Airlines' initial statements about the incident.

The U.S. National Transportation Safety Board said it is aware of the incident and is gathering information. Separately, the NTSB is still investigating the battery fire that occurred on the Japan Airlines 787 in Boston a year ago, and said last week it is due to complete that investigation in March. The agency did not say whether the latest battery incident would affect the timing of the Boston investigation.
The U.S. Federal Aviation Administration said it was working with Boeing and the Civil Aviation Bureau of Japan to investigate the battery malfunction. The agency certified Boeing's revamped 787 battery system as safe last year after the Dreamliner fleet was grounded for more than three months.
The agency also launched a review of the design, manufacture and assembly of the 787 in January last year and said its report would be released last summer, but it has so far not released the report and has not responded to questions about when that review would be finished.
