The pair of General Electric GEnx engines were installed inside the centerpiece final assembly building on Boeing's campus in January. But they couldn't be fueled and started until Monday as the plane sat in its flightline stall near the Aviation Avenue delivery center.
The engine run is part of a battery of tests the Boeing delivery center team has been performing in the days following the plane's rollout event on April 27, spokeswoman Candy Eslinger says.
"Everything's progressing well with the airplane," Eslinger says.
Boeing executives have said the plane will fly for the first time this month, but no date has been yet been released.
Delivery to Air India, which will be accompanied by another major celebration, is expected early this summer.
