A family of twin-engine regional jets produced by Bombardier from 1991 until the present.

The Bombardier CRJ (Canadair Regional Jet) is a series of aircraft made by since 1991, 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.
