Design and development

In the late 1950s, Pierre Robin, a French flying instructor, was interested in building a three-seat version of the Jodel D11 light aircraft. The result of a collaboration between Robin and the designer of the Jodel, Jean Delemontez was the Jodel DR.100 Ambassadeur,[2] which made its maiden flight on 14 July 1958.[3]

The Ambassadeur was certified on 10 July 1959,[3] entering production both at Robin's own company, Centre-Est Aeronautique at Dijon and under license by Société Aeronautique Normande at Bernay.
