The final assembly andacceptance engine testof the Pratt & Whitney PurePower® PW1200G enginesfor the Mitsubishi Regional Jet (MRJ) will be performed by Mitsubishi Heavy Industries (MHI) Nagoya Guidance & Propulsion Systems Works located in Komaki, Aichi Prefecturein a production phase. After the final assembly, the PW1200G engineswill be transferred to MHI Nagoya Aerospace Systems Works Komaki South Plant located in Toyoyama, Aichi Prefecture. The engineswill be installedonthe wingatthe newly constructed MRJ final assembly line located next to Nagoya Komaki Airport,where the first flight will take place.

The MRJ PurePower® PW1200G engine is developed in the United Statesbut in a production phase,since its final assembly will be conducted by MHI, both enginesand the aircraft will be finished in Aichi Prefecture where the headquartersof Mitsubishi Aircraft Corporation is located. MHI has vast experience in engine manufacturing and hasbeen involved the in the Pratt & Whitney PW4000 engine project, International Aero Engines V2500 engine project, and also Rolls-Royce TRENT1000 project. As MHI will be conducting final assemblies of both the airframe and engine, Mitsubishi Aircraft Corporation and MHI will be able to work closely to build a more flexible and more effective production system. The development of the engine at Pratt & Whitney is proceeding smoothly, and PW1200G engine flight test program that commenced on April 30

thjust completed successfully its first flight test program on June 21st.

“It is such encouragingnews that the MRJ engine first flight test program completed successfully and thatengine development is running smoothly,” said Hideo Egawa, President, Mitsubishi Aircraft Corporation. “As we will be conducting the engine final assembly here, weare looking aheadtoward the mass production of the MRJ as well as conducting flight testing on schedule.”
