    The CF34-8 turbofan
    The workhorse of regional aviation
    A larger version of the classic CF34-3 engine, the advanced CF34-8 offers:
    • A 14,500 lb. thrust class turbofan propulsion system
    • 50% more thrust
    • Higher thrust-to-weight ratio
    • Lower specific fuel consumption
    • Reduced number of parts
    • Improved maintainability
    The CF34-8 engine provides the level of reliability and performance that has earned the CF34 family of engines a global reputation for exceptional service.

    The CF34-3 turbofan
    Proven performance and reliability
    over four decades
    The CF34-3 is the sole-sourced engine on the reputable Challenger 650 business jet. It also powers the Bombardier CRJ200 regional airliner.
    • 8,729 lbs. of thrust
    • 99.99% on-time departure rating
    • 61 million cumulative cycles
    In markets where reliability, durability, and time-on-wing matter, the CF34-3 consistently delivers. GE Aerospace’s CF34-3 engine started out in military as the TF34, most famously on the A-10 in the early 1970s. Since its service entry in 1992 on the Challenger 601, the CF34-3 engine has earned an industry-leading reputation as one of the cleanest and most fuel-efficient engines in its class, while being synonymous with reliability.
