GE Aviation is introducing an updated version of its CF34 turbofan engine with engine-leasing group BeauTech and Toronto-based Sky Regional Airlines. The CF34-8 HPT (high-pressure turbine) durability upgrade program will see GE Aviation provide customers with improved versions of parts that can be incorporated into an engine during its next scheduled overhaul.
The CF34-8 is a turbofan propulsion system installed in Bombardier CRJ900 and CRJ700 Series aircraft. The HPT durability upgrade program is available to all CF34-8 operators, regardless of their maintenance, repair and overhaul provider. Since its service entry in 2001, the CF34-8 engine has accumulated 70 million flight hours and 52 million flight cycles.
The updated parts available include components in the fan, compressor, combustor and HPT modules, and according to GE will improve durability and "time on wing," and will bring the total cost of ownership "in line with customer expectations."
"During the last 12 months, we have been focusing on driving durability into the CF34-8 engine through several enhanced design improvements," stated David Kircher, general manager of Regional Engines and Services at GE Aviation. "The HPT durability upgrade program will stabilize the engine's operation and reduce unscheduled engine removals and significant events, allowing CF34-8 customers to more effectively plan their operations."
