Boeing said it will redesign part of the software on the 787 Dreamliner’s electrical system and its power panels after an onboard fire two weeks ago halted flight tests.
The incident has set back the Dreamliner programme once more, although Boeing is yet to finalise a schedule for the plane’s certification and delivery.
The six Dreamliner test jets have been parked since the November 9 fire, in which the affected aircraft lost its primary power and the crew had to evacuate on emergency slides after the plane landed in Laredo, Texas.
Boeing said in a statement that engineers have determined that the fault began as either a short circuit or an electrical arc in the power distribution panel, most likely caused by the presence of foreign debris.
