West Chester, OHIO – 6 March 2024 – CFM International has finalized various agreements with American Airlines, Inc. (“American”) for LEAP-1B engines to power the airline’s Boeing 737 MAX 8 and MAX 10 fleet. The agreements, which among other things provide for the purchase of spare engines, include a new 20-year service agreement covering American’s existing and new LEAP-1B engines.

“Over the past decade, we have invested heavily to modernize and simplify our fleet, which is the largest and youngest among U.S. network carriers,” said American’s Chief Financial Officer Devon May. “We’re very pleased to partner with CFM to service our entire Boeing 737 MAX fleet with newer, more efficient engines so we can continue to deliver the best network and record-setting operational reliability for our customers.”

In addition to the 737 MAX family, American also operates 303 CFM-powered Boeing 737 Next-Generation aircraft.

“American’s continued commitment to the LEAP-1B demonstrates trust in the asset utilization, performance and environmental benefits that our products deliver,” said Gaël Méheust, president and CEO of CFM International. “We are committed to proving that American has made the right choice, as the CFM team works each day to deliver world-class products and services that our customers can rely on.”

The advanced CFM LEAP engine family provides 15% to 20% better fuel consumption and lower CO2 emissions, as well as a significant improvement in noise compared to previous generation engines. Since its entry into service in 2016, the LEAP engine has allowed CFM customers to reduce CO2 emissions by more than 32 million tons. *
