The story
Beginning in the late 1960s, the company produced a two-seat trainer aircraft for the Brazilian Air Force, the Aerotec A.122 Uirapuru. Thirty units were produced for the civilian market. The Uirapuru was also exported to Bolivia and Paraguay.
Thereafter, Aerotec produced mainly components for Embraer until 1980. At that time, the Brazilian Air Force showed interest in a performance-enhanced version of the Uirapuru. A prototype with an improved cockpit canopy and enlarged tail unit was built as the A.132 Uirapuru II. Since the Brazilian Air Force did not order this aircraft, only a few examples were produced for Bolivia.
In 1987, the company was acquired by Embraer.
