GE Delivering New GEnx Durability Upgrade
GE expects to complete deliveries throughout the in-service 787 fleet within two years.
The GEnx-1B has won about a 65 percent share of the Boeing 787 propulsion market to date, and nearly 90 percent in the last 12 months, claims GE.

GE Aviation (Outside Exhibit P2) is ramping up production of a new durability upgrade it certified early this year for GEnx-1B engines and—having delivered 14 sets of the upgraded hardware to Boeing 787 operators for installation in their in-service GEnx-1Bs by early June—expects to complete retrofitting the upgrade throughout the in-service GEnx-1B fleet within the next two years.

“At this point, essentially everything is finished in terms of the design work from a performance and durability perspective and it is now in production,” Kathy Mackenzie, general manager of the GEnx program, told AIN. “It went into production at the end of last year and we have incorporated it into MRO [visits]. We have delivered 14 into MRO, and by the end of this year, we’ll be into full production,” both for retrofitting GEnx-1B engines already in service and in new-production engines.
