The Companhia Aeronáutica Paulista CAP-9 Carioca four-seat, single-engine high-wing monoplane with enclosed cockpit and fixed undercarriage, was CAP’s last attempt, in 1947, to remain in the aircraft market. The company had chosen to build the CAP-9 Carioca instead of the CAP-8. The CAP-8 (which reached the prototype stage) was a 4-seater low-wing aircraft and although the prototype was made of wood in order to gain time (the war was about to end but there was still a shortage of aluminum), the idea was to build an all-metal aircraft.
Without commercial success with its new projects and a vertiginous drop in its orders, CAP ends its activities in 1948.
