Classic Light Aircraft-The Aerotec Uirapuru

By Willie Bodenstein

The Aerotec A-122 Uirapuru Brazilian military trainer aircraft that first flew on 2 June 1965 and was a low-wing monoplane with tricycle undercarriage that accommodated the pilot and instructor side-by-side.

In October 1967, when the Brazilian Air Force ordered thirty Uirapurus, it was still flying obsolete Fokker S.11s in the training role. They eventually ordered another seventy for a total of 100. The Bolivian Air Force ordered 36 examples in 1974, which flew until 1997 and in, 1975, the Paraguayan Air Force bought eight aircraft to replace the Fokker T-21 (S.11). Most of them were withdrawn from service in 1992.

Thirty others were sold in the civilian market. A total of 155 were built, including prototypes by the time production finished in 1977.
