Hawaiian Airlines has finalised deals with General Electric to purchase at least 20 GEnx engines to power its Boeing 787-9s, and to have GE maintain those engines.
The purchase, finalised in a definitive agreement reached by the companies on 1 October, also gives Hawaiian options to purchase another 20 GEnx and "a number of spare engines", Hawaiian says in a regulatory filing.
Also on 1 October Hawaiian signed a flight-hour services deal with GE Engine Services, under which GE will maintain Hawaiian's GEnx for 10 years. The agreement could be extended for six years after that, Hawaiian adds.
The Honolulu-based airline estimates that the combined deals, including all options, could cost $1.7 billion.
Hawaiian ordered 10 787-9s earlier this year, saying at the time that it had selected GEnx engines to power the aircraft. Airlines can also purchase 787s with Rolls-Royce Trent 1000 powerplants.
The airline does not hold options for any more aircraft, according to FlightGlobal's Fleets Analyzer database.
Hawaiian expects to begin receiving its 787-9s in 2021, it says.
Airlines have chosen GEnx to power about 60% of the in-service and on-order fleet of 787s, Fleets Analyzer shows. Rolls-Royce holds 30% share of those aircraft, while engine choices on 10% of that fleet remain undisclosed, data shows.
