The first prototype, assembled in Italy, made its maiden flight on 15 May 1984. This first aircraft was lost on its fifth flight in an accident, resulting in the death of its pilot. Aside from this early loss, testing progressed smoothly and without further incident. The first Brazilian-assembled prototype made its first flight on 16 October 1985.

Deliveries of production aircraft to Italy began in 1988, the first examples were delivered to the Brazilian Air Force during the following year.
