Bombardier CRJ1000 Engine - GE CF34-8C5A1 CF34-8C5A2

The Bombardier CRJ1000 Engine is based on the General Electric CF34-8C5 series of engines. Two of the following engines are mounted in the tail section of the CRJ1000 regional jet. The CRJ1000 actually has 3 options for engines according to the CRJ1000's FAA type certificate and press releases from GE Aviation. The CRJ1000 Engines are the GE CF34-8C5, CF34-8C5A1 and the CF34-8C5A2 turbofan engines. Bombardier has been using the GE CF34-8C5A1 Engine as the examples in marketing materials. The only difference between the three engines is the normal takeoff thrust which greater on the -8C5A1 and even more greater on the -8C5A2. This difference is listed/marked below in the specifications. Also note that the CRJ900 Engines are also the CF34-8C5 and CF34-8C5A1 engines.
