Aerotec A-122 Uirapuru A-122 Uirapuru Role - Primary Trainer National origin - Brazil Manufacturer - Aerotec S/A Indústria Aeronáutica First flight - 2 June 1965 Produced - 1968-1977 Number built - 155 Developed into - Aerotec A-132 Tangará The Aerotec A-122 Uirapuru was a Brazilian military trainer aircraft. It was a low-wing monoplane with tricycle undercarriage that accommodated the pilot and instructor side-by-side. It first flew on 2 June 1965. Design and development 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 eight aircraft to replace the Fokker T-21 (S.11). In 1986, six more were donated by the FAB. Most of them were withdrawn from service in 1992, replaced by the Enaer T-35 Pillán. As of 2009, only one T-23 is in flying conditions. Thirty others were sold in the civilian market. A total of 155 were built including prototypes by the time production finished in 1977. The T-23 suffered fatal accidents during spin training. The problem was solved after a crash in which an instructor described his stricken aircraft's responses to his control inputs all the way to the end. Uirapurus then received a ventral fin under the rear fuselage to correct the issue. In 1980 interest by the airforce in an improved version led to the development of the Uirapuru II, later known as the A-132 Tangará.

Design and development The A-132 Tangará was developed in response to a request from the Brazilian Air Force. Compared to its predecessor, the Uirapuru II had a longer fuselage, greater wingspan, larger fin, more powerful engine, and a redesigned, flat-sided fuselage. A similar aircraft with a less powerful engine was planned for the civil market. The prototype first flew on 26 February 1981. The Air Force originally had the intention to order 100 units but after a decision that the primary trainer should have tandem seats, the project was abandoned. The only orders came from the Bolivian Air Force, which ordered 6 units in 1986 and flew them until 1992. The prototype was given to the Air Force Technical Institute in 1990 where it was used for tests until 2004. It was then passed on to the Aeroclube de Sao Jose dos Campos, where it was flying with experimental restrictions, with a 200 hp (150 kW) engine from a Socata ST-10 Diplomate.
