PALM BEACH, Florida | September 25, 2017

In 1992, GE Aviation's CF34-3 engines helped launch a new era in aviation when it entered service on Bombardier's CRJ100 aircraft, spawning the beginning of the regional jet segment in commercial aviation. Now 25 years later, the CF34 engines continue to set the standard for performance, durability, and reliability for regional jets around the world.

Today, the CF34 engine family powers more than 12,000 daily passenger flights operating in 130 countries and 1,400 cities. That adds up to 4.4 million passenger flights and 140 million flight hours accumulated annually on Bombardier, Embraer and Comac aircraft.

Since its original service entry in 1983 on the Challenger 601 business jet, the CF34 has earned an industry-leading reputation as one of the cleanest, quietest and most fuel-efficient engines in its class. These rugged powerplants set a new standard for reliability and low maintenance costs.

With a 99.95% dispatch reliability and outstanding durability, the CF34 engine has enabled operators to provide exceptional service that their customers demand.

GE's commitment to the CF34 remains strong- to support and invest in the engine line-so customers can keep the CF34-powered regional jets flying for years to come.

"We continue to drive innovation for the CF34 product line in hardware upgrades, utilization differentiation and digital solutions," said Dave Kircher, general manager of regional engines and services for GE Aviation. "Additionally, we are driving several Services solutions to make our overall CF34 cost of ownership even more competitive."

Engines in the CF34 engine family include:

CF34-10E: GE has delivered more than 1,500 CF34-10E engines for Embraer's E190/195 aircraft and the EMBRAER Lineage 1000 business jet. With the highest thrust rating for the CF34 engine family at 20,000 pounds of thrust, the CF34-10E engine has accumulated 24 million flight hours and 17 million cycles. Since entry into service, fuel burn on the CF34-10E engine has improved by more than 2 percent due to design enhancements and optimization.

CF34-10A: The CF34-10A engine powers the Commercial Aircraft Corporation of China (COMAC) ARJ21 regional jet, the first regional jet to be designed and built in China. The first aircraft was delivered to Chengdu Airlines in late 2015. COMAC received its production certificate in July and has announced orders for more than 250 ARJ21 regional jet aircraft and forecasts a demand for up to 850 aircraft over the next 20 years.

CF34-8: More than 3,200 CF34-8 engines have been delivered to 85 operators of Bombardier CRJ700/CRJ900s (1470) and Embraer's E170/175s (870) aircraft. The engines have accumulated more than 53 million flight-hours and 40 million cycles. Since entering service in 2001, GE has made improvements to the combustor, HPT blades and nozzles to improve durability and time on wing for severe environment operations.

CF34-3: More than to 2,200 CF34-3A1 and -3B1 engines power the Bombardier CRJ100/200 aircraft and have accumulated more than 62 million flight hours and 55 million cycles.
