The CAP series has its ancestry in the CP.30 Emeraude of the early 1960s. One company which built the Emeraude was CAARP, owned by Auguste Mudry, and the CP.30 was used as the basis for the CAP 10. The CAP 10 was generally similar to the CP.30, but the 50 or 65kW (65-90 hp) Continental engines were replaced by a 135 kW (180 hp) Lycoming, and the airframe was stressed for aerobatic flight.
The CAP 10 first flew in August 1968, and the first 30 were built for the French air force. Only in 1972 was production begun for civil orders, by Mudry's other aviation company, Avions Mudry.
The CAP 10B remained in production, with enlarged tail, and was joined by the single seat CAP 20 with a higher powered engine. The CAP 21 replaced the CAP 20 in 1981, introducing an entirely new wing and undercarriage, and leading to the CAP 231 and 232 models.
With Mudry's bankruptcy in 1997, Akrotech Europe took over the CAP series |
