SEATTLE – Boeing resumed flight tests of its long-delayed 787 Dreamliner on Thursday, six weeks after they were suspended because of an in-flight electrical fire in the jetliner’s power distribution system.
The company said it installed an updated, interim version of the software that controls the system in the first of six test flight aircraft.
The fire that broke out on a Nov. 9 test flight to Laredo, Texas, was among the most recent in a string of problems that have plagued the 787.
The company did not unveil a new delivery schedule for the airplane, which is already three years late.
“We expect to complete our assessment of the program schedule in January,” said Scott Fancher, a Boeing vice president and general manager of the 787 program.
