The design was started in 1959 for a four-seat cabin monoplane aircraft with a high wing and fixed undercarriage.

The prototype, designated the Neiva Regente 360C, was first flown on 7 September 1961 with a 145 hp (108 kW) Continental O-300 piston engine.

The type was ordered into production by the Brazilian Air Force with a more powerful 180 hp (134 kW) Lycoming O-360-A1D engine.

Its tailcone was lowered in order to improve visibility, and it used a more powerful Continental IO-360D 210 hp engine.
