Ryanair and CFM International signed a purchase agreement for 30 CFM LEAP-1B spare engines. The engines will support Ryanair’s growing fleet of Boeing 737 MAX aircraft. Ryanair has been a CFM customer since 1998, operating the largest fleet of CFM-powered Boeing airplanes, including the largest CFM56-powered Next-Generation 737 fleet in Europe. The Ireland-based airline currently operates 181 LEAP-powered 737-8-200 aircraft, with 29 aircraft still to be delivered from a 2014 order. Ryanair placed a new order in 2023 for LEAP-1B engines to power 150 firm and 150 option Boeing 737-10 aircraft.
Michael O’Leary, CEO of Ryanair commented:“We are pleased to continue to develop our longstanding partnership with CFM. Today’s purchase of 30 new LEAP-1B spare engines is a significant commitment to improve the operational resilience of our Group airlines. These latest technology CFM engines reduce fuel consumption and CO2 emissions per seat by up to 20% when installed on our B737 MAX fleet, which will further widen Ryanair’s cost leadership over competitor airlines in Europe.”
Gaël Méheust, president and CEO of CFM International stated: “This new agreement is another milestone in the long and successful partnership we have built with Ryanair. We look forward to continuing to support Ryanair’s significant growth by providing them with industry-leading reliability and utilization standards.”
Since entering service, CFM LEAP-1B engines have accumulated nearly 30 million flight hours and 12 million cycles. The advanced CFM LEAP engine family reduces fuel consumption CO2 emissions by 15 percent compared to CFM56 engines, along with a significant reduction in noise.
