About the incident aircraft

The CRJ900, registered as C-FUJZ, is a 15.5-year-old regional jet that has flown with Jazz Aviation for its entire service life. With Jazz Aviation’s arrangement with Air Canada, the carrier has mainly used the jet for Air Canada services, typically under the banner of Air Canada Express.

While the aircraft was built as a Bombardier CRJ705, websites like refer to it as a Mitsubishi CRJ900. Why is this?

Once Bombardier, now Mitsubishi

The aircraft was originally built by Bombardier as the CRJ705. However, with Bombardier’s assistance, Jazz reconfigured 16 of its CRJ705 aircraft into CRJ900s, with 76 seats, rather than the 75. The CRJ200, CRJ700, and CRJ900 families of aircraft all have avionics and cockpit systems commonality with one another, meaning that all models can be flown by the same pilot pool, which significantly reduces training costs.

Last June, Canadian manufacturer Bombardier confirmed the closing of the previously announced sale of the CRJ Series aircraft program to Japan’s Mitsubishi Heavy Industries (MHI). This deal was a cash consideration of approximately $550 million. Under this sale, MHI acquires the maintenance, support, refurbishment, marketing, and sales activities for the CRJ Series aircraft, including the related services and support network located in Montréal, Québec, and Toronto, Ontario. The deal also sees CRJ service centers located in Bridgeport, West Virginia, and Tucson, Arizona go to MHI, as well as the relevant type certificates.

Simple Flying reached out to Jazz Aviation for a statement on the incident. However, at the time of writing, no response was received from the airline.
