The ST10 “Diplomate” is a four-seater touring aircraft developed in the late 1960s. It was derived from the Gardan GY-80 Horizon which had made its first flight in July 1960, and was first called Super Horizon 200, then Provence and finally Diplomate. It differs from the GY-80 by a larger cabin, a wider and electrically retractable landing gear, and a more powerful engine.
The aircraft made its first flight on November 7th, 1967. At the beginning of 1969, the prototype was modified: its fuselage is elongated and the wingspan of its tail is reduced, the surface of the fin is enlarged and it receives a keel under the tail. Thus amended, it receives its type certificate from the General Civil Aviation Secretariat (SGAC) on November 27th, 1969.
The aircraft was produced in serie from 1969 to 1974. Only 55 production copies were produced, including six for the Brazilian company Varig where they were used to train pilots. Production of the aircraft was short-lived due to competition with other products within Socata.

Our aircraft is the prototype. A team went to Supaero enginner school in September 2003 to disasemble it and bring it back to our site. In Supaero the ST10 was used as course material.
After years, exhibited outdoors, the paint was faded. It has been painted again in 2012 by IFIP, a training center.
