CFM International CFM56-5B1
CFM International CFM56-5B1 exact turbofan variant in EASA TCDS E.003. EASA rates constant takeoff thrust below 30 °C at 13,345 daN (133.45 kN; 30,000 lbf) and maximum continuous thrust below 25 °C at 12,940 daN (129.40 kN; 29,000 lbf). EASA lists the base CFM56-5B1 separately from the /P, /2P, and /3 suffix variants; this record preserves that certified model boundary without asserting an installation or service-entry date.
