The Bombardier Model CL.600-2B16 (or CL-604) Challenger is a twin-engine executive jet aircraft for
2 crewmembers and up to 19 passengers. Development of the CL-600 Challenger family started in 1974, when Bill
Lear designed the LearStar 600, a 12-place business jet. Canadair bought the manufacturing rights in 1976,
and renamed the design Canadair CL-600 Challenger. The first prototype of the airplane flew on 8 November 1978.
The second and third prototypes flew in March and July 1979. On 3 April 1980, a test flight with
the first prototype above the Mojave Desert ended in a disaster, with the airplane crashing due
to a deep stall. In August 1980, certification was granted with temporary restrictions. Deliveries of
the CL-600, powered by two Lycoming ALF-502L turbofans started in 1981. The design
was developed further and on 10 April 1982 the Challenger 601, a refined version with more
powerful General Electric CF-34 engines and winglets, made its maiden flight.
In 1983, the CL-601 replaced the CL-600 in production. In 1986 Bombardier Aerospace bought Canadair.
The Bombardier Challenger became a family of business jets. A number of models entered
production including in 1989 the CL-600-2B16 or Challenger 604 powered by CF-34-3B engines.
First flight with this engines was on 17 March 1995, with Transport Canada
certification granted that September. First delivery was in January 1996.
