General Electric CF34-8E5A1
General Electric CF34-8E5A1 exact turbofan variant in the CF34-8 series. EASA rates normal five-minute takeoff thrust at 62.50 kN (14,050 lbf), maximum takeoff thrust at 64.54 kN (14,510 lbf), and maximum continuous thrust at 60.14 kN (13,520 lbf). GE identifies the CF34-8E as the Embraer E170/E175 powerplant; the existing Embraer E170 family relationship remains separate from this propulsion identity, and no A1-specific service date is inferred from family-level milestone material.
