Taiwanese carrier EVA Air has selected GE Aviation's GEnx-1B engine to power 24 of its 787 aircraft and ordered an additional two GE90-115B for its 777-300ER order.
The 777s are expected for delivery in 2017 while the 787 aircraft will begin delivery in 2018.
Along with the new engines, EVA Air has also signed a 12-year OnPointSM solution agreement for the MRO of its GEnx-1B and GE90-115B engine fleet.
The new engines and OnPoint solution agreements are valued at more than $2bn at list prices.
EVA Air president Austin Cheng said: “We believe the future of the airline industry will be built on fuel efficiency and cabin comfort.
The new Boeing 787-10 Dreamliner’s high fuel efficiency and long-range flying capabilities meet these requirements and our operational needs.”
