(FAA)-certification test flights recommenced Monday when Dreamliner No. 4 took off Monday from Yuma, Arizona. After updating power system software and vigorous testing, flight readiness had been confirmed for the Boeing 787 Dreamliner. Plagued with problems based on it’s composition frame and other issues, Dreamliner’s delivery date has been pushed back and back and back. Monday’s fuel jettison test, which incorporated a test on the electronic equipment bay, was successful.
Earlier in testing a Rolls-Royce engine blew up, and later, Boeing attributed the test fiasco in Laredo to debris in the electrical panel, hence the inclusion in Monday’s test flight. Hardware changes were proposed after that test.
Boeing says they need the FAA to agree to the fixes and to restart certification test flights.
