The CFM International LEAP-1A32 is a certified model in the LEAP-1A turbofan series. EASA describes the series as a high-bypass, dual-rotor engine whose fan and core compressor are driven by separate turbine systems, under full-authority digital control. The unsuffixed -1A32 is listed separately from -1A32X, -1A32R, -1A32S and -1A32RS configurations. Those exact designations matter when selecting approved ratings, limitations and installation data.
