GE Aviation has launched a new CF34-8 high-pressure turbine (HPT) durability upgrade programme for CF34-8 engines to improve fleet stability, time on wing and engine’s cost of ownership.

The HPT durability upgrade programme is available to all CF34-8 operators, regardless of their maintenance, repair and overhaul provider. The CF34-8C5 powers the Bombardier CRJ700, CRJ900 and CRJ1000, while the CF34-8E powers Embraer 170/175 aircraft.

Under the CF34-8 HPT durability upgrade programme, GE Aviation will provide customers with upgraded parts that can be incorporated into the engine during its next overhaul. These parts are listed in a series of Service Bulletins that GE issued and include components in the fan, compressor, combustor and HPT modules.

These upgraded parts offered at a significant discount combined with the improved durability and time on wing will bring the total cost of ownership in line with customer expectations.

General manager of regional engines and services at GE Aviation, David Kircher, said: “During the last 12 months, we have been focusing on driving durability into the CF34-8 engine through several enhanced design improvements.

“The HPT durability upgrade programme will stabilise the engine’s operation and reduce unscheduled engine removals and significant events, allowing CF34-8 customers to more effectively plan their operations.”

Launch customers for the durability upgrade are BeauTech Power Systems (BPS) and Sky Regional Airlines. BPS (based in Dallas, Texas) specialises in the leasing, trading, asset management and sales of aircraft engines.

Sky Regional Airlines, based in Etobicoke, Ontario, operates 25 Embraer 175 aircraft under the Air Canada Express banner.

Since its service entry in 2001, the CF34-8 engine has accumulated 70 million flight hours and 52 million flight cycles.
