Hawaiian Airlines has selected Pratt & Whitney PurePower 1133G-JM engines to power its new fleet of Airbus A321neo aircraft, the Honolulu-based carrier announced.
Pratt & Whitney will also provide Hawaiian with "off-wing engine maintenance" through its PureSolution Fleet Management Program, the airline says.
Hawaiian finalised an agreement with Airbus in March to purchase 16 of the jets with deliveries between 2017 and 2020, and an option to purchase an additional nine. The deal is worth $2.8 billion at list prices.
The A321neo is offered with either the CFM International Leap-1A engine, which will use advanced materials like ceramic matrix composites, or the Pratt & Whitney PurePower, which has a reduction gear that improves the efficiency of the inlet fan.
Airbus has received orders for some 370 A321neos from 16 airlines and lease companies, according to Ascend.
"We are continuing our commitment to invest in cutting-edge equipment and technology that will be kinder on our environment and, through greater fuel efficiency, kinder on everyone's pocketbooks," Hawaiian president and chief executive Mark Dunkerley says in a statement. "The new technology PurePower engines are part of Hawaiian's commitment to find new ways to reduce the cost of travel to the benefit of our customers and to our tourism-dependent community."
Six of the companies that ordered A321neos have selected Pratt & Whitney engines for 90 aircraft and two companies have selected the CFM International Leap-1A for 16 aircraft.
Operators of the remaining 264 aircraft have not announced an engine decision.
Todd Kallman, president of P&W commercial engines, says the company optimized the PurePower PW1100G for a mission between the specifications for the A320neo and A321neo, and that has allowed them to be more competitive for the largest aircraft in the family.
David Hess, P&W president, adds that the geared architecture also helps the engine burn fuel at lower temperatures at higher thrust levels, compared to the CFM Leap engine. That means the engine will require less maintenance over time and provides better overall performance.
Hawaiian has said the jet will carry 190 passengers in a two-class configuration and, according to Airbus, will have a "design range" of 3,650nm (6,760km).
The airline has declined to name the cities it plans to serve with the aircraft, but says the aircraft will likely fly between Hawaiian cities other than Honolulu and US west coast cities that are already served by the airline.
Dunkerley told Flightglobal in January that the new routes could connect the US mainland to island markets like Hilo, Kona and Lihue.
Hawaiian did not say if the carrier will fly the A321neos to further US cities like Las Vegas, Nevada, and Phoenix, Arizona, which are roughly 2,400nm and 2,500nm from Honolulu, respectively.
Those cities might be at the "outer limits" of the A321neo's range, Hawiian says says.
Hawaiian already flies from Honolulu to the California cities of San Diego, Los Angeles, San Jose,San Francisco, Oakland and Sacramento, as well as to Seattle, Washington and Portland, Oregon. The airline also flies from Kahului on the island of Maui to Seattle, San Jose and Oakland.
