The P.59 Jolly was designed to meet a requirement for a standard trainer for the Italian national flying clubs.
The prototype first flew on 2 February 1960 and was a high-wing monoplane with a nose-mounted 95 hp (71 kW) Continental engine.
It had a fixed tailwheel landing gear and seated two occupants side-by-side in an enclosed cockpit.
The aircraft was later re-engined with a 100 hp (75 kW) Continental O-200 engine and the wing span was increased.
