Boeing Co has found a way to fix battery problems on its grounded 787 Dreamliner jets that involves increasing the space between the lithium ion battery cells, a source familiar with the U.S. company's plans told Reuters.
"The gaps between cells will be bigger. I think that's why there was overheating," said the source, who declined to be identified because the plans are private.
A spokeswoman for the U.S. National Transportation Safety Board declined comment on the Reuters report or any Boeing plan to return the 787s to the air.
"The decisions to return the airplane to flight will be made by the FAA and only after Boeing has demonstrated to them that the solution is adequate," Kelly Nantel said. "We continue to investigate the cause of the short circuiting."
A spokeswoman from the U.S. Federal Aviation Administration declined to comment. Boeing declined comment on details of any battery fix it may be considering.
