Engine manufacturer CFM International (Stand G23) plans to test 15 Leap engines this year as part of a development program leading to certification of the Leap-1A for the Airbus A320neo next year. Also part of the program, the Leap 1B and -1C versions are to power the upgraded Boeing 737 Max and the new Comac C919 narrowbodies, respectively. The engine’s designers promise a 15-percent fuel burn advantage over the current CFM56.
