Development and design
In October 1968, the French aeronautical engineer Chris Heintz, who worked for Avions Pierre Robin, started work on the design of a two-seat all-metal light aircraft suitable for amateur construction, the Zenith, with the prototype making its maiden flight on 22 March 1970.[1]
Heintz migrated to Canada in 1973,[2] and set up Zenair in 1974 to sell plans and kits of the Zénith.[3] The Zenith, which gained the designation Zenith CH 200 when Heintz produced plans for larger and smaller derivatives, is a low-winged cantilever monoplane of all metal construction. The pilot and passenger sit side by side under a clear, sideways-opening plexiglas canopy, while the aircraft is fitted with a fixed nosewheel undercarriage. It is designed to be powered by a single piston engine of between 85 and 160 hp (63.5 and 119 kW).[4]
The first Zenith to be built in North America flew in October 1975, and by 1976, over 300 plans had been sold.[5] Plans continued to be available in 1999, by which time hundreds were flying.[6]
At the 1976 EAA Convention in Oshkosh, Wisconsin the factory used volunteer labour to build and fly a CH 200 in eight days, using 550 person-hours.[7]
Variants

- Initial version. Could be built as a cross country cruiser with an engine of 85 to 125 hp (63 to 93 kW) or as an aerobatic trainer with modifications and a powerplant producing 125 to 160 hp (93 to 119 kW). The aircraft can be constructed as a taildragger or on tricycle gear and flown as a skiplane or on floats.[7]
