Kenya Airways has opted for General Electric GEnx powerplants for its Boeing 787 fleet, days after the twinjet secured certification with the engine type.
Nine firm 787s as well four options are covered by the agreement. GE values the firm part at $380 million.
Kenya Airways chief Titus Naikuni says the 787 will be 15-17% more fuel-efficient than the carrier's Boeing 767s.
The carrier ordered six 787-8s in 2006 and followed up with an order for three more in the same year.
Boeing obtained certification of the 787 with the GEnx-1B powerplant last month.
