At the end of year 2026, the Eastern European in-service engine fleet is expected to reach over 4,214 engines. The CFM56-5B engine will lead the fleet, making up 18% of the overall fleet share, but newer types such as CFMs LEAP and Pratt & Whitney’s PW1100G-JM will make strong inroads during the next decade.
