GE Aviation's CF34 turbofan line has surpassed 200 million flight hours and 157 million flight cycles, the company said at the Farnborough Airshow.

“In the history of GE and CFM (the 50-50 joint venture of GE and Safran), only the CF6 and CFM56 engine lines have accumulated more commercial flight hours,” GE said. 

Starting in 1983, the CF34-1A entered service on the Bombardier Challenger business jet. In 1992, the CF34-3 powered the first Bombardier CRJ100 airliners, marking the launch of the regional jet industry as a distinct class of commercial aviation. Today, GE claims the CF34 line, in -3, -8, and -10 versions, powers more than 3,600 regional commercial aircraft.

“The CF34 engine began as a business aviation engine, then paved the way for powering regional jet aviation,” said Cristina Seda-Hoelle, GE general manager for regional and business aviation. “Surpassing 200 million hours is a remarkable achievement that goes to our customers who put their trust in us, operating our engines day in and day out.”

GE has delivered more than 8,000 CF34 engines and said the line’s reliability record for 12-month rolling dispatch reliability ranged between 99.96 and 99.99 percent.

“All CF34 engines, like all GE engines, can operate on approved SAF fuel blends today,” the company said. “All CF34-powered aircraft can take advantage of GE Digital aviation software solutions to help improve aircraft performance, giving up to 2- to 3 percent better fuel burn on a regional route.”
