Air France-KLM has finalized the purchase of 200 fuel-efficient CFM International LEAP 1-A engines to power its new fleet of Airbus A320neo and A321neo aircraft. Air France-KLM has been a long-standing CFM customer and selected the LEAP engine as part of a strategy to renew and expand its fleet.

“We are honored to further expand our partnership with one of the industry’s largest groups and to be an integral part of Air France-KLM’s sustainability strategy,” said Gaël Méheust, president and CEO of CFM International. “This renewed trust is a valuable recognition of LEAP engine performances in terms of sustainability and fuel efficiency.”

CFM is a 50-50 joint company between GE and Safran Aircraft Engines. CFM started developing the LEAP jet engine two decades ago. The engineers were able to lower fuel consumption by 15%, lower COemissions and make it quieter compared with the engine’s predecessor, the CFM56, by using breakthrough materials and technologies. Since its entry into service in 2016, the LEAP engine has saved more than 14 million tons of CO. It has logged more than 20 million engine flight hours to date in commercial service.

The engine uses parts made from advanced light- and heat-resistant material called ceramic matrix composites (CMCs) that can handle temperatures approaching 2,400 degrees Fahrenheit, where even the most advanced alloys grow soft. In general, jet engines can operate more efficiently at higher temperatures.

Air France-KLM airlines currently operate CFM56-7B and CFM56-5B engines that power the Boeing Next-Generation 737 and Airbus A320ceo fleets, respectively.
