In 1945 students at the Instituto Nacional de Tecnica Aeronautico of the Escuela de Ingenieros de Construcciones Civiles y de Minas began efforts to design a conventional high-wing cantilever monoplane with fixed tricycle undercarriage that might serve as a primary training aircraft for the Fuerza Aérea del Perú or as a private ‘club’ trainer. Assembly of a prototype began early in 1946, and the aircraft made its maiden flight in January 1947. Construction throughout is of wood. The pilot and a single passenger or instructor sit side by side.
In June 1947 orders were placed by the Fuerza Aérea del Perú for an initial quantity of forty T-21 aircraft to serve as ab initio or ‘grading’ trainers, while a further twenty-one aircraft were funded by the Ministry of Production for distribution to aero clubs across the nation.
