The Bombardier Challenger 600 series is a family of business jets designed by Bill Lear and produced first by Canadair until that company was bought by Bombardier Aerospace in 1986.

Development

The aircraft was an independent design by Bill 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. The Challenger was also one of the first bizjets designed with a supercritical wing.

On 8 November 1978, the prototype aircraft took off at Montreal, Canada. The second and third prototypes flew in 1979. An 3 April 1980 test flight in the Mojave Desert resulted in disaster, the aircraft crashing due to the failure of the release mechanism to detach the recovery chute after a deep stall, killing one of the test pilots (the other test pilot and the flight test engineer parachuted to safety).[1]

Despite the crash, both Transport Canada and the Federal Aviation Administration in the United States certified the aircraft in 1980, albeit with restrictions to pilots including a limited maximum take-off weight. A program to reduce the aircraft's weight was then implemented to improve the aircraft's range.

Challengers can be identified visually by their distinctive fowler flap design, where the fairings can be seen below the wings, a sight much more common on commercial airliners.

Variants

CL-600

CL-601

CL-604

  • CL-604 Multi-Mission Aircraft: militarized version in Danish service.[4][5] The aircraft are employed on maritime patrol and search and rescue missions.[4][5] They are capable of landing on the short, rough, gravel airstrips common in the Arctic.[6]

CL-605

CL-610

The CL-610 Challenger E was to have been a stretched version for use as a cargo plane by Federal Express, or alternatively, as a passenger aircraft with seating for 24 passengers.[7] Federal Express placed orders for 25 CL-610s, but these orders were canceled after the passage of air cargo deregulation in the US in 1977.[8] 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.
