(CNN) - Boeing says a test flight of one of its grounded 787s went "according to plan."
The jet maker says Monday afternoon's "functional check flight" lasted a little more than two hours out of an airport in Everett, Washington. The FAA pulled all of the 787 Dreamliners from the sky in January due to smoking batteries.
Boeing has been searching for a solution to the battery problem. A second battery certification flight test is planned in the coming days.
