The Aerotec A-122 Uirapuru 2 seat Brazilian military trainer aircraft first flew on 2 June 1965, powered by a 108 hp Lycoming O-235-C1 engine. A second followed powered by a 150 hp Lycoming O-320-a and was offered to the Brazilian Air Force as a replacement for its locally built Fokker S.11 and S.12 basic trainers. Thirty Uirapurus were ordered for this purpose early in 1968 under the military designation T-23. 40 more were ordered in 1969. They have a 160 hp Lycoming O-320-B2B and differ from the civilian model in having fully-adjustable seats, stick controls, a nose wheel the same size as the mains, and a modified cockpit canopy in which only the centre portion slides rearward.
Following the loss of the first production T-23 in 1968, a small ventral fin was added to improve spin recovery.
They were used by Brazilian, Bolivian & Paraguayan Air Forces.
