Fourteen AT-27s were ordered in 1992, and delivery of the first six units took place in December of the same year, followed by seven more units arriving later that same month. Assigned to the Combat 212 Squadron, the aircraft were initially conceived as trainers, although the type was soon additionally assigned to perform close air support and air superiority missions as part of counter-insurgency operations during the long-standing and brutal fight with the FARC. The type performed dozens of operations including Vuelo de Angel, Thanatos, Fenix and Júpiter. Over 50,000 flight hours have been completed since the type's introduction without a single loss.
