The CF34 engine is a derivative of combat proven TF34 military engine, which powers US Air Force A-10 and US Navy S-3 Viking, intended for regional jet aircraft. It has an outstanding reliability, durability and availability specially suited to high frequency routes. Moreover, the engine is considered environmentally safe due to its low noise and smoke emissions. These characteristics make CF34 the engine of choice for 50 to 100 passengers regional jets.
The first CF34 engine entered service in 1983 powering the Bombardier Challenger 601 corporate jet. Since then, it has been selected to power Bombardier CRJ-100, -200, -700 and -900, Bombardier Challenger 601/604, Brazil's Embraer 170/190 family of aircraft, and China's ACAC ARJ21. The engine, rated at 9,220 to 20,000 pounds of thrust, comprises three main models: CF34-3, CF34-8 and CF34-10.
The CF34-8 is a 14,000-pounds class turbofan designed for regional jets of 70-90 seats capacity. It inherits the reliability, environmental and operational characteristics of CF34-3 engines. The first engine, a CF34-8C1, entered service in 2001 powering a Bombardier 70-seat CRJ700. In 2003, Bombardier launched the 90-passenger CRJ900 powered by two CF34-8C5 engines. The CF34-8E model entered service in 2004 powering the Embraer 170 and Embraer 175 regional jets.
On 24 May 2005, General Electric made public that Austria-based carrier Styrian Spirit was ordering the Bombardier CRJ700 aircraft equipped with CF34-8C5B1 engines. At the same time, US-based carrier GoJet Airlines also was ordering the CRJ700 powered by CF34-8C5B1 engines. The CF34-8C5B1 powers the Bombardier CRJ900 passenger aircraft as well.
