Development

The aircraft was an independent design by Lear in 1976, who had resigned as Chairman of Lear Jet seven years previously. Originally dubbed the 'LearStar 600', Lear sold exclusive rights to produce and develop the design to Canadair, who renamed it the 'CL-600 Challenger'.
While similar in general configuration to Lear's previous designs, notable changes were made that distinguished the new aircraft from the Learjets, including the use of a widened fuselage that allowed a 'walk-about cabin', a feature not shared by any other business aircraft of the time.
On November 8 1978, the first prototype of the aircraft took off for the first time in Montreal, Canada. An April 3 1980 test flight in the Mojave Desert resulted in disaster, the aircraft crashing due to a deep stall, killing one of the test pilots (the other parachuted to safety). The second and third prototypes flew in 1979.
Despite the crash, both Transport Canada and the Federal Aviation Administration in the United States certified the aircraft in 1980, albeit with both handing over some restrictions to pilots including a limited maximum take-off weight. A large program to reduce the aircraft's weight was then implemented to improve the aircraft's range.

CL-604

★ 'CL-604' - major upgrade of the 601 design, incorporating more powerful engines, larger fuel supply, completely new undercarriage, structural improvements to wings and tail, and a new electronic flight instrumentation system. The 'C-143A' is a single Challenger 604 aircraft, which was acquired by the United States Coast Guard in December 2005 as its new Medium Range Command and Control Aircraft (MRC2A).^[1]

CL-605

★ 'CL-605' - Introduced in early 2006 as an avionics and structural upgrade of the 604 design. Structural improvements include larger cabin windows. Cockpit instrumentation updated with new avionics displays and "electronic flight bag" capability.

CL-610

★ 'CL-610 Challenger E' was to have been a stretched version with seating for 24 passengers. Development was halted by Canadair in 1981 without any having been built. A few years later, a new project would develop the Canadair Regional Jet based on a stretched Challenger design.
