CF34Engine Family
Setting the standard
for reliability in regional
and business aviation
and business aviation
With more than 7,500 CF34 engines powering regional aircraft, this engine family has logged more than 209 million flight hours and 165 million flight cycles. The CF34 has truly set the standard for performance, durability, and world-class reliability.
The CF34-10 turbofan
Best-in-class reliability and performance
The CF34-10 engine represents a considerable capability increase over the other CF34 engine models.
- Up to 20,000 pounds of thrust
- Low-risk with proven technology
- Low operating costs through high reliability, ease of maintenance, and best-in-class fuel economy
The CF34-10E powers both Embraer’s 190/195 and Lineage 1000 aircraft. The CF34-10A powers the COMAC C909 regional jet.
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 CF34-8E powers the Embraer E170/175 regional jets. The CF34-8C powers the CRJ series of regional jets.
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 engine is the sole-sourced engine on the best-selling large business jet platform, Challenger 650 business jet. It also powers the 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.
