A BOEING 787 with a redesigned battery system made a two-hour test flight on Monday, and the company said the event "went according to plan."
The test flight was an important step for Boeing Co in its bid to convince global safety regulators to let airlines resume using the plane the company calls the Dreamliner.
Boeing will analyze information from the flight and prepare for another flight using the same plane to demonstrate the 787's performance to the US Federal Aviation Administration, company spokesman Marc Birtel said.
The timing of that flight has not been set, Birtel said.
Boeing hopes to get 787s flying again within weeks, not months, but that decision will be made by aviation regulators in the US, Japan and elsewhere.
Worldwide, airlines own about 50 Dreamliners.
The fleet has been grounded since January after lithium-ion batteries on two planes overheated.
The battery on a Japan Airlines 787 caught fire after it landed in Boston, and the battery on an All Nippon Airways jet began smoking during a flight in Japan, forcing an emergency landing.
Boeing added insulation around battery cells and a steel casing on the outside to prevent fires.
Company officials have said that they might never know the cause of the smoldering batteries. The US National Transportation Safety Board and Japanese authorities are investigating.
For Monday's test flight, Boeing used a 787 that it built for LOT Polish Airlines.
The plane took off about an hour later than planned from Paine Field near Seattle, flew out over the Pacific and down the coast to Oregon before returning to the airfield.
Birtel said the crew tested landing gear, electrical and backup systems to show that all functioned as designed.
The same plane had a similar test flight in January, but that was before the changes to the battery system.
