Boeing said it will resume flight test activities on the 787 Dreamliner later today.
The company, which hasn't conducted test flights on the new plane since an inflight fire on Nov. 9, said it has installed an interim version of updated power distribution system software and conducted a rigorous set of reviews to confirm the flight readiness of ZA004, the first of the six flight test airplanes that will return to flight.
"Initially, we will resume a series of Boeing tests that remain to be completed in the flight test program. That testing will be followed later by a resumption of certification testing," Scott Fancher, vice president and general manager of the 787 program, said in a statement.
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," Fancher said.
