Boeing says it has made changes to the battery system on its Dreamliner 7-87 aircraft that should allow the planes to resume passenger flights.
At a news conference earlier today in Tokyo, the company presented improvements to batteries the company says it believes will prevent future fires.
Battery fires prompted the grounding of Dreamliners worldwide.
Changes include a new fire-proof stainless steel enclosure around batteries.
The F-A-A must approve the changes before Dreamliners can carry passengers again.
Boeing admits it may never determine exactly what caused fires on planes in Boston and Japan earlier this year.
