The EMB121A1-Xingu is a twin-turboprop fixed-wing aircraft built by the Brazilian aircraft manufacturer, Embraer. The design is based on the EMB 110 Bandeirante, using its wing and engine design merged with an all-new fuselage. The EMB121 was the first pressurized aircraft manufactured by Embraer and first flew on October 10, 1976. A modified variant of the EMB 121, the EMB 121A1-Xingu II, was introduced on 4 September 1981 with a more powerful engine (PT6A-135), increased seating and a larger fuel capacity. Before production ceased in August 1987, Embraer had produced 106 EMB 121 aircraft, 51 of which were exported to countries outside Brazil. Currently, the French Air and Space Force is the largest operator with 22 aircraft still in service.
