Boeing completed its first flight of the 777X powered by two GE9X engines on January 25. GE Aviation has been designing and testing the GE9X since 2013, having conducted 72 test flights of the GE9X totaling more than 400 hours on its Boeing 747 flying test bed in Victorville, CA.
To date, the GE9X program has completed more than 4,100 hours of ground and air testing, as well as 6,500 cycles. GE Aviation is wrapping up certification testing for the GE9X and expects the engine to be certified later this year. Eight GE9X engines and two spares have been produced to support the Boeing test program. Engines for the first three aircraft have been delivered and the balance will be in Seattle in the coming weeks.
