In February 1973 Chasle started the design of the side-by-side two-seat Sprintair, a conventional all-metal low-wing monoplane, with non-retractable tricycle landing gear, flaps, one-piece horizontal tail surfaces with tab, and the cockpit is covered by a forward-hinged and jettisonable one-piece canopy, and has a rear-view transparent panel aft of seats. Powerplant is an 100 hp Rolls-Royce Continental O-200-A four-cylinder horizontally-opposed engine.
Construction of the prototype began in the Autumn of 1973, and it was built by some twenty members of the Leon Morane Club (hence the designation
LMC-1), the aero club of Socata (the light aircraft subsidiary of Sud Aviation/Aérospatiale) at Tarbes. Registered F-PXKD (c/n 01) it flew for the first time on June 18, 1975, and since has been employed that time as a training aircraft at the Leon Morane Club.
The pictured example was constructed by members of the Association les Ailerons Toulousians (Toulouse Aero Club) at Toulouse, and was registered
F-PPIA on April 26, 2001. The following year March 27, it was transferred to the Aéro-club René Barbaro de l'Aérospatiale Toulousaine (Aero Club René Barbaro of Aérospatiale, Toulouse). Additional photo (Henk Wadman Collection).
