History Mitsubishi SpaceJet JA21MJ
First flight 11 November 2015



MHI first announced the concept in June 2007, then targeting certification for 2012, as the first Japanese airliner since the 1962 NAMC YS-11. After a delayed development, the maiden flight of the MRJ90 took place on 11 November 2015. In June 2019, Mitsubishi rebranded the Mitsubishi Regional Jet (MRJ, Japanese: 三菱リージョナルジェット) program as the SpaceJet. As flight testing took longer than expected, the scheduled entry into service was further pushed back until development was first paused in October 2020, and subsequently cancelled altogether in February 2023.

The Mitsubishi SpaceJet (Japanese: 三菱スペースジェット, originally named Mitsubishi Regional Jet) was a regional jet project by Japanese company Mitsubishi Aircraft Corporation (MAC), a Mitsubishi Heavy Industries (MHI) subsidiary.

Development

The Pratt & Whitney PW1000G geared turbofan

In 2003 the Japanese government started a five-year, ¥50 billion ($420 million) research program to study an indigenous regional jet for 30 to 90 passengers, led by Mitsubishi Heavy Industries (MHI).

In 2004 MHI was focused on a 2m high by 2.8m-wide, four-seat-abreast cabin, seating 30 to 50 passengers, and was hoping to fly a prototype in 2007 and deliver the first aircraft in 2010.

In 2005 it switched to a larger 70-90 seat category.

The aircraft had several airworthiness issues early in its service history. Airworthiness directives (ADs) were issued for nose gear cracks and various problems with the TPE331 engine.
