The Cook JC-1 Challenger was a 1960s American cabin monoplane built by the Cook Aircraft Corporation.

Development

John Cook founded the Cook Aircraft Corporation in 1968 at Torrance, California to build and market his JC-1 Challenger cabin monoplane design.

The Challenger was a low-winged cantilever four-seat monoplane with an all-metal construction. It was powered by a single 150 horsepower (110 kW) Lycoming O-320 piston engine and had a fixed nosewheel undercarriage. Two prototypes were built, the first aircraft flew in May 1969. A third prototype was built in 1971 but crashed in 1972 killing the pilot Cook. A fourth modified prototype was built by the company but was never certified and the company stop all design and development in the mid 1970s.
