Mitsubishi Aircraft Takes Delivery of Engine for MRJ’s First Flight Test Aircraft

Nagoya, June 5, 2014 – Mitsubishi Aircraft Corporation took delivery of the first PurePower® PW1200G
engine at the Mitsubishi Regional Jet’s (MRJ) final-assembly factory in Aichi Prefecture, Japan. Pratt &
Whitney shipped the PurePower engine in preparation of being mounted on the first MRJ flight test aircraft. The
delivery of the engine marks a major milestone toward MRJ’s completion, accelerating the final-assembly
process with components. Pratt & Whitney shipped the PurePower 1200G engine from the Mirabel Aerospace
Centre in Mirabel, Quebec, Canada.

P&W’s PurePower PW1000G series, with its unique Geared Turbofan™ technology, delivers significant
operating cost and environmental benefits through increased efficiency. The engine’s low-pressure system
operates at higher speeds for peak efficiency, while the fan operates at slower speeds for both optimum
efficiency and significantly less noise. Pratt & Whitney designed the PW1200G engine exclusively for the MRJ.
Mitsubishi Aircraft remains firmly committed to the success of the MRJ program through strong partnerships
with its suppliers worldwide.
