A flight labeled the "final" certification test of an improved battery system for the grounded Boeing 787 Dreamliner was "straightforward" and "uneventful," the airplane maker said Friday.
The test was an important one for Boeing, which has billions of dollars riding on the success of the new airliner. The U.S. Federal Aviation Administration and similar regulators worldwide grounded the Dreamliner in January after two battery-related fires damaged 787s in Boston and Japan. No one was hurt in the fires.
In March the FAA approved a Boeing certification plan to fix the 787's problematic lithium-ion battery system and prove the new design is safe. Friday's nearly two-hour flight was the final certification test of that plan.FULL STORY
