It first flew on 2 June 1965.In October 1967, the Brazilian Air Force ordered 30 aircraft to replace the obsolete Fokker S.11s and S.12s (T-21s and T-22s) that were operating in the Air Force Academy. Later, they ordered another 40, and then 30 more. These were designated T-23.The Bolivian Air Force ordered 36 examples in 1974, which flew until 1997, and in 1975 the Paraguayan Air Force bought 8 aircraft to replace the Fokker T-21 (S.11).
