Development

The AS-70 was developed during 1945 as a single-seat light low-wing monoplane aircraft to serve the early postwar needs of French private pilots and aero clubs. It is of mixed welded steel tube and wooden construction with fabric covering, and is fully aerobatic.^[1]

A small series of Jacs was constructed by Avions Starck. These were fitted with a range of engines with power outputs of between 45 and 65 hp (34 and 48 kW).^[1] Different designations were given to aircraft powered by the various engines, as listed below.

Operational history

The Jac proved to be a popular aircraft with private pilots and aero clubs and four examples remained in service in 2009.^[2]
