NEW YORK, N.Y. - Boeing says it is ready to move quickly to get its 787s fixed and back in the air if it gets U.S. federal approval for a fix for the batteries that have grounded the planes.

Boeing submitted a plan to the Federal Aviation Administration on Feb. 22. Now it needs the FAA to approve its plan and ultimately to certify the design. The FAA has said it expects its experts to recommend this week whether to accept Boeing's plan.

Ray Conner, who runs Boeing Co.'s commercial airplane unit, described the process to analysts on Monday. Conner didn't lay out a timeline to get the 787 flying again. It's been grounded since Jan. 16 after a battery fire on one plane and an emergency landing caused by smoke from another battery.
