Remarks by Johan Visschedijk: "Auguste Mudry formed CAARP (Coopérative des Ateliers Aéronautiques de la Région Parisienne, Cooperative Aeronautical Workshops Paris region) at Beynes-Thiverval, to the west of Paris, in 1965. It was, at first, primarily a design bureau with Claude Piel, Louis de Goncourt and Nenad Hrissatovic as its technical leaders.

In August, 1966, CAARP flew the prototype of the Piel CP.100 which was a 160 hp development of the Super Emeraude with a larger nose and taller fin and rudder. With a broader chord rudder and various other modifications it later emerged in production form as the CAP 10 two-seat trainer. Encouraged by a French Air Force order for 26 aircraft, the company started building the CAP 10 in 1970.

The first prototype (F-WPXU c/n 01) of a single-seat aerobatic aircraft based on the CAP 10 and designated Cap 20, was first flown on July 29, 1969. The second prototype (pictured above) was registered to CAARP as F-BOPV on July 9, 1970, and it participated in the 6th FAI World Aerobatic Championships, which were hosted at RAF Hullavington. Flown by Robert Baudouin as racer number "10", it placed 43rd.

The French AF ordered six examples for the EVAA (Equipe de voltige de l'Armée de l'Air, Air Force Aerobatic Team), the second prototype replaced a CAP 20 of the EVAA (c/n 2, call sign F-TFVV, coded VV), which had crashed June 30, 1974.

Struck off charge, it was registered as F-ZWRP, later F-BTAI, and since May 20, 2005, it is registered as F-AZOE."
