"The supply chain for the GE9X engine has a wide global footprint, stretching from our facilities in Canada, Italy, Poland and the US to our international participants located in Belgium, France, Germany and Japan," said Ted Ingling, general manager of the GE9X engine program at GE Aviation. "Several sites, such as Peebles, Durham, Batesville and Avio Aero's Pomigliano, had to make significant changes to accommodate the engine's large size."

Final assembly is well underway on the first full GE9X engine that will test in the first half of 2016, four years before the GE9X engine enters service on a Boeing 777X aircraft.

Testing is underway on the first demonstration core for the GE9X engine that will power the Boeing 777X aircraft.
