An Ethiopian Airlines 787 Dreamliner is due to take off from Addis Ababa on Saturday morning, the first commercial flight by the Boeing aircraft since all 787s were grounded in January.
The 50 planes around the world were grounded due to battery malfunctions that saw one 787 catch fire in the US.
Over the past week teams of Boeing engineers have been fitting new batteries to the aircraft.
BBC Transport Correspondent Richard Westcott spoke to Rich Horigan, systems engineering leader from Boeing, at Addis Ababa airport.
