SEATTLE (AP) — Boeing says it is done for now with flight tests to find the source of the battery problems on its 787s.
Boeing ran the second test flight of a 787 on Monday. It says the flight, which lasted for about an hour and a half over Washington state, was uneventful.
The 787s are grounded because of battery problems that caused one fire and forced another plane to make an emergency landing. Federal officials grounded the 787 on Jan. 16. Boeing won permission from the Federal Aviation Administration last week to conduct test flights.
Boeing says Monday's flight included two pilots and 11 flight test personnel.
The aircraft maker has said the test plane includes special equipment that lets it track the conditions of the batteries during the flight.
