Design and development

The MS.603 was one of three aircraft constructed in the MS.600 series which were built to compete in an officially-sponsored 1947 contest for a light two-seat side-by-side club aircraft to be powered by a 75 hp engine.

The initial MS.600, powered by a 75 hp Mathis G-4F piston engine, was a fixed gear, low-winged monoplane

 and a clear perspex canopy over a side-by-side cockpit for two persons. All three aircraft, MS.600, MS.602 and MS.603, were ready for flight in 1947 with the MS.600 flying on 4 June 1947.

A parallel development, the MS.602, powered by a 75 hp Minie 4DA piston engine, was similar in most respects to the MS.600 and flew on 24 June 1947.
A more powerful derivative emerged as the MS.603, powered by a 100 hp Hirth HM 504A-2 engine and fitted with a fixed tricycle undercarriage. The tailplane was also moved to a high set position on the fin and supported by struts.
