The Mitsubishi Regional Jet (MRJ) is a twin-engine regional jet aircraft seating 70–90 passengers manufactured by Mitsubishi Aircraft Corporation, a partnership between majority owner Mitsubishi Heavy Industries and Toyota Motor Corporation with design assistance from Toyota affiliate Fuji Heavy Industries, already a manufacturer of aircraft. Pictures of the first fully assembled MRJ90 were available on June 26, 2014 and an official rollout occurred on October 19. Its maiden flight is scheduled for 2015, with first deliveries to follow in 2017. It will be the first airliner designed and produced in Japan since the NAMC YS-11 of the 1960s, which was produced at a loss. The jet's North American final assembly for North American & South American customers will be built by Mitsubishi Heavy Industries Canada Aerospace in Mississauga, Canada.
Design and development
The aircraft was initially expected to be the first regional jet aircraft to adopt carbon-fiber-reinforced polymer 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 wingbox instead of composite material. Carbon composite parts will now make up only 10-15% of the aircraft, primarily around the tail section. These changes required an increase in cabin height by 3.8 cm (1 1⁄2 in) to 204 cm (80 1⁄2 in) and a fuselage height increase to 296 cm (116 1⁄2 in). This gave the MRJ a rounder cabin, which is wider and higher than 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 was planned to begin in 2012. The first flight, scheduled after the design was finalized, was to take place in the second quarter of 2012, but was delayed to 2013, and then further delayed to spring 2014 due to delays in the procurement of engines. Likewise the first delivery was planned to take place in the first quarter of 2014, but was delayed to mid to late 2016.
In August 2013, Mitsubishi announced a third major delay to the program, and that the first flight would take place by summer 2015 while the first delivery would take place by summer 2017. Delays in the procurement of the Pratt & Whitney engines and other components were cited as the cause of this delay.
In September 2013, after announcing the third delay to the MRJ program, Mitsubishi publicly displayed a prototype MRJ fuselage, including cockpit enclosure, and announced that it would hire foreign pilots and technicians to serve as consultants as the program progressed to safety testing and regulatory approvals.
On 15 September 2010, the Mitsubishi Aircraft Corporation announced that it had entered the production drawing phase and was proceeding with the manufacturing process. Assembly of the first aircraft began in April 2011 with construction of the emergency escape for the cockpit.
A new production facility for the aircraft will be built at Komaki Airport in Nagoya, Japan, on land purchased from the government at a total cost of 60 billion yen. Production at this plant is expected to commence in fiscal year 2016, with the new plant producing 10 aircraft per month and employing 2,000 workers. Mitsubishi announced in June 2013 that it would establish a quality control facility in Illinois for the sourcing of MRJ components from the United States. MHI employs new production methods such as integral wing stringers, unusually tight tolerances, shot peening of curved surfaces, and A-Vartm. These methods are intended to increase quality and thus reduce expensive fault correction to keep price competitive. In 2008, Mitsubishi estimated that 3-400 MRJs would be necessary to recover the $1.9-billion programme cost.
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.
In March 2008, and again in October 2008, Sankei Shimbun and Fuji Sankei Business I reported that the government of Japan would buy ten MRJs to serve as short-haul and small-field VIP transports, supplementing the existing Japanese Air Force One Boeing 747 aircraft. The government was still considering this option as of July 2013, with MRJs possibly supplementing new Boeing 777 long-haul VIP transports, according to the Nihon Keizai Shimbun.
At the Farnborough International Airshow July 2012, SkyWest agreed to buy 100 MRJ90's, to be delivered between 2017 and 2020. The deal is worth $4.2bn at list prices.
During the 2013 Regional Airlines Association conference, held in Montreal, Canada, Mitsubishi announced that ANI Group Holdings, which firmed a MoU for 5 MRJ aircraft in June 2011, cancelled the deal, without giving further details.
