Japanese made MRJ flight test jets have been on the ground since 13 February 2018. Mitsubishi Aircraft’s four flight test jets are on the ground for more than the month at Moses Lake, Washington, USA.
The MRJ manufacturer said the aircraft have been undergoing upgrading in Avionics and software handling flight controls in order to be certified to enter into production.
Until today, the four flight test airplanes had flown a total of some 1,500 hours and expected to have busy test flights this year. MRJ was launched in 2008, and was due for delivery in late 2013, but it has since been repeatedly delayed, mainly due to complying with certification requirements.
The 88 seat jet is powered by Pratt & Whitney PW1200 engines, is preparing to get MRJ certified by late 2019 and targeting first delivery to launch customer All Nippon Airways in mid-2020.
The Mitsubishi Regional Jet(MRJ), is a twin-engine regional jet will be the first airliner designed and produced in Japan since the NAMC YS-11 of the 1960s, which was produced at a loss.
