A family of twin-engine regional jets produced (originally by Bombardier, now by Mitsubishi Heavy Indstries) from 1991 until the present.

The Bombardier CRJ (Canadair Regional Jet) is a series of aircraft made by from 1991 to 2020 and by Mitsubishi Heavy Industries from 2020 onwards, derived from (and, legally, still variants of) the Challenger 600 business jet. All CRJs are powered by twin tail-mounted General Electric CF34 engines.

There are two major families of the CRJ:

CRJ100 family

Officially the CL-600-2B19, these variants use CF34-3 series engines. 1021 were built between 1991 and 2006.

  • The CRJ100 entered service with in 1992; it seats 50 passengers in its standard configuration, and has a range of up to 3,056 km (1,650 nmi).
  • The CRJ200 is identical to the CRJ100, except for having slightly more efficient engines which marginally increase its range.
  • The CRJ440 is a 44-passenger variant of the CRJ100, produced to get around union contract restrictions which formerly prevented some airlines from using 50-or-more-passenger aircraft.

CRJ700 family

These variants feature a stretched fuselage, larger wings (which, unlike those on the CRJ100 family, feature leading-edge ), and more efficient CF34-8 engines. 833 have been built since 1999 (plus 33 of the business-jet version, the Challenger 800), with 60 orders yet to be filled.

  • The CRJ700 (officially, the CL-600-2C10) first flew in 1999, and entered commercial service in 2001. It seats 63-78 passengers, and can fly up to 4,660 km (2520 nmi) without needing to refuel. The CRJ550 (legal name not yet known), announced in February 2019, is a 50-seat version for regional airlines that can't fly larger aircraft due to union contract restrictions.
  • The CRJ900 (CL-600-2D24), a 76-to-90-passenger stretch of the CRJ700 with a larger wing and tail, entered service in 2003; it is also offered in a 75-passenger version, the CRJ705 (CL-600-2D15), to comply with union contract restrictions preventing some connector airlines from flying aircraft with more than 75 passenger seats.
  • The newest and largest CRJ is the CRJ1000 (CL-600-2E25), a further stretch of the CRJ900, which first flew paying passengers (up to 100 of them per CRJ1000) in December 2010.
