About the ST-10 Diplomate
The Socata ST-10 Diplomate functions as a French civil light fixed-wing aircraft laid out for four occupants. It features a single horizontally-opposed piston engine driving a constant-speed propeller in a low-wing monoplane configuration.
Rooted in an earlier horizon design, the aircraft progressed through preliminary naming stages before adopting its final designation. Initial prototype testing occurred in the late sixties, with manufacturing commencing soon after. Assembly operations concluded in the mid-seventies following a modest overall build quantity.
