According to a CNN report, earlier tests conducted in Washington showed that a lithium-ion battery that caught fire aboard an empty JAL Boeing 787 Dreamliner in Boston this month was not overcharged, the National Transportation Safety Board.
Suspicions about the batteries and a possible fire risk prompted the U.S. Federal Aviation Administration and other nations to ground all 50 Dreamliners worldwide last week, pending an investigation of the Boston fire and other reports of mechanical problems.
The stakes are high. Dreamliner, which costs about $200 million and debuted 15 months ago, is the first major airliner to be rolled out in years. United Airlines is the only current American operator of the aircraft. It has six. The airline began the nation's first domestic 787 routes in November.
