CFM International CFM56-5B2

CFM International CFM56-5B2 exact turbofan variant in EASA TCDS E.003. EASA rates constant takeoff thrust below 30 °C at 13,789 daN (137.89 kN; 31,000 lbf) and maximum continuous thrust below 25 °C at 12,940 daN (129.40 kN; 29,000 lbf). EASA lists the base CFM56-5B2 separately from the /P, /2P, and /3 suffix variants; this record preserves that certified model boundary without asserting an installation or service-entry date.

    Note
    The approved-model list names CFM56-5B2 separately from CFM56-5B2/P, /2P, /3, and other suffixes; EASA TCDS E.003 ratings give 13,789 daN constant takeoff thrust below 30 °C and 12,940 daN maximum continuous thrust below 25 °C for the base model.
