Mitsubishi Regional Jet MRJ 70 and MRJ 90 The Mitsubishi Regional Jet (MRJ) is a passenger jet aircraft seating 70-96 passengers to be manufactured by Mitsubishi Aircraft Corporation, a partnership between majority owner Mitsubishi Heavy Industries and Toyota Motor Corporation. The aircraft program was expected to be launched in early 2008. It would be the first airliner Japan has designed and produced domestically since the NAMC YS-11 of the 1960s. Design and development The MRJ will be the launch platform for Pratt & Whitney's PW1000G Geared Turbofan engine. The aircraft was initially expected to be the first regional jet aircraft to adopt carbon fiber composite materials for its airframe on a significant scale. However, in a design turn-around in September, 2009, Mitsubishi announced that it would use aluminium for its wing box instead of composite material. Carbon composite parts will now make up only 10-15% of the aircraft, mostly around the tail section. This change brought increase in the cabin height by 1.5in (3.81 cm) to 80.5in (204.47 cm) and fuselage height increase to 116.5in (295.91 cm) This gave the MRJ a rounder cabin, which is wider and higher than its competing aircraft manufactured by Bombardier and Embraer. A cabin mockup and a scale model were presented at the 47th Paris Air Show in June 2007. The company has decided to formally offer the aircraft for sale to potential customers. Production is planned to begin in 2012. All Nippon Airways is the first customer, with an order for 15 MRJ 90s, and an option for 10 more. Trans States Holdings, owner of Trans States Airlines which operates flights for United Express and US Airways Express, is the first international customer with an firm order of 50 jets, plus an option for 50 more. Variants Four versions are planned using two different fuselage lengths The MRJ70 will have a passenger capacity of 70-80 and the MRJ90 will have a passenger capacity of 86-96.
