The Max Plan PF.204 Busard was a French-built light sporting monoplane of the early 1950s. Following some modifications it was redesignated as PF.214; a planned derivative, the PF.215, was never made. The plane led to the subsequent construction of the Lefebvre Busard, a single-seat racing aircraft built marketed for homebuilding.
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.[1]
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.[2] 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.[3] By 2006 the aircraft was in storage at the Musée Regional de l'Air,[4] Angers - Loire Airport, France.[5]
