Design and development
Design work on the Aéro 20 began in June 1965 and construction started in that September. It first flew on 11 June 1966 and received its amateur category SGAC certification in August 1968.
It is a conventional single-engine low-wing monoplane, seating two in tandem. The wings are wooden structures with fabric covering. They carry 5° of dihedral and are braced with struts running from the upper fuselage longerons to the upper wing surface. There are no flaps. The tail surfaces are also built of wood, with fabric covering. The fin and rudder are tall, tapered and straight edged. The elevators carry trim tabs.
The fuselage of the Aéro 20 is flat sided, with wooden longerons and frames, plywood covered and with a rounded decking. The two seats, with a small baggage space behind were originally enclosed under a continuous canopy. The aircraft is powered by a 90 hp (60 kW) Continental C90-8 flat 4-cylinder engine. The fixed, tailwheel undercarriage has spring steel shock absorber main legs with a track of 2.44 m (8 ft); no brakes are fitted.
Only one Aéro 20 was built, but it seems to have continued flying until at least 2006. By then the canopy had been discarded and replaced by a pair of small windscreens and the wheels enclosed in spats. F-PKXY remains on the French civil register in 2010.
