General Electric CF34-3A2
General Electric CF34-3A2 exact turbofan variant in the CF34-1/3 series. EASA rates normal five-minute takeoff thrust at 38.83 kN (8,729 lbf), APR takeoff thrust at 41.01 kN (9,220 lbf), and maximum continuous thrust at 40.66 kN (9,140 lbf). GE documents CF34-3A2 engines in service on Challenger 601 aircraft and ongoing upgrade/support work; the existing Challenger 601 family relationship remains separate from this propulsion identity.
