The PF.204 Busard was designed and built by Monsieur Max Plan for personal use as a racing and sporting monoplane. The PF.204 was of all-wood construction with plywood skin. The aircraft was fitted with a fixed cantilever undercarriage enclosed by light alloy fairings.
Only one example of the Busard was completed in 1952. By 1956 it had received several modifications, the most noticeable being a revised engine cowling and enlarged cockpit; at this point it was redesignated the PF. 214. At that time there were plans to replace the Minié with a 90 hp (67 kW) Continental C90 4-cylinder horizontally opposed engine, producing the PF.215.
After some years of active flying, it was placed in storage at Mitry-Mory airfield on the northeast outskirts of Paris by May 1957. It no longer appeared on the French civil aircraft register by 1964. By 2006 the aircraft was in storage at the Musée Regional de l'Air, Angers - Loire Airport, France.
