LOS ANGELES—As part of a major shake-up of its regional jet strategy, Mitsubishi Aircraft has rebranded the former MRJ90 as the SpaceJet M90 and has announced details of the stretched MRJ70 redesign which will now be called the M100.

Details of the revamp, which come as the Japanese manufacture continues negotiations with Bombardier over the potential acquisition of the CRJ regional jet program, emerge on the eve of the Paris Air Show at which the rapidly changing state of the regional airliner market is expected to be a major talking point.

Compared to the original 109.7 ft. long MRJ70, the M100 fuselage is extended to 113.2 ft. to accommodate 76 passengers in a three-class layout. Despite the larger fuselage, which is now just 4 ft. shorter than the M90, Mitsubishi has managed to restrict maximum take-off weight to 86,000 lb. by improving structural efficiency and reducing wing span by around 4 ft.

The change is designed to make the M100 more competitive under current scope clause restrictions governing regional aircraft in the U.S. market, and comes as Mitsubishi enters the final phase of the long-running MRJ90/M90 certification campaign.

Announcing the revamp, which has been in the works since late 2018, Mitsubishi Aircraft Corp. president Hisakazu Mizutani said the “SpaceJet family represents our plan to redefine the business of regional air travel. This is a commercial segment where we see great opportunity. The SpaceJet M100 is the result of our research and development during the past few years and the answer to the regional market’s current and future needs.”

The revised M100 does suffer a range drop as a result of the redesign with a maximum range of 1,910 nm. with a full payload, compared to just over 2,000 nm. for the original version. However, Mitsubishi says this will still give the aircraft with a full payload and in a single class with a 225 lb. allowance per passenger, the ability to fly from Paris to Moscow, Singapore to Taipei or Denver to Miami.

The company, which plans to debut the M100 cabin interior at the show, says the program will be formally launched in 2020. Flight tests of the M90 meanwhile remain on track towards certification by the Japan Civil Aviation Bureau (JCAB) by early 2020, with entry-into-service with All Nippon Airways by the middle of next year. The certification process is being shadowed by the FAA and EASA which are expected to grant approval of the new airliner later next year.
