Boeing Co. (BA) officials are preparing proposed fixes to ensure that the 787 Dreamliner’s battery won’t damage the plane or emit smoke as they work to end the jet’s grounding, people with knowledge of the talks said.

A Boeing team is scheduled to meet tomorrow in Washington with the U.S. Federal Aviation Administration, said the people, who weren’t authorized to discuss the session and asked not to be identified. The plan includes a harder battery case and a venting mechanism for fumes, one person said.

Any repairs would be subject to FAA approval, and agency Administrator Michael Huerta is to participate in tomorrow’s meeting, the person said. The FAA isn’t expected to act immediately unless tests show the fixes can ensure safety, the person said. Battery changes also would need the backing of U.S. Transportation Secretary Ray LaHood, who has said the 787 won’t fly again until the U.S. is “1,000 percent sure” it’s safe
