UTVA-75

The UTVA 75 is a light utility and primary training aircraft produced by the Serbian manufacturer UTVA. Development began in the early 1970s to replace the UTVA Aero 3 as the primary basic trainer for the Yugoslav Air Force. The prototype made its maiden flight in 1976, and production commenced in 1978. Between 1978 and 1985, a total of 136 UTVA 75s were produced for the Yugoslav Air Force. Following the dissolution of Yugoslavia, the aircraft were transferred to successor states including Serbia, Slovenia, Croatia, Montenegro, Bosnia and Herzegovina, Republika Srpska, and North Macedonia. Additional export customers include the Sudanese Air Force and the Somaliland Armed Forces, which purchased four aircraft for military and civilian use.

Design

The UTVA 75 is an all-metal, semi-monocoque low-wing monoplane featuring a fixed tricycle landing gear. The cockpit accommodates two occupants in a side-by-side seating arrangement equipped with dual controls, accessible via upward-opening gull-wing doors. Air scoops are integrated into the central front frame of the cockpit for ventilation. Power is supplied by a four-cylinder, air-cooled Lycoming O-360 engine; standard specifications list the 180 hp (134 kW) Lycoming IO-360-B1F variant driving a two-bladed Hartzell variable-pitch metal propeller. Avionics consist of standard instruments for Visual Flight Rules (VFR) flight, including an airspeed indicator, altimeter, and vertical speed indicator. Standard avionics packages include the KING KR85 ADF and KING KY 195B, with optional systems such as the KING KR87 ADF, RNAV KING KNS81 VOR/LOC, and KING KT 79 transponder.

Armament

For offensive or utility roles, the aircraft features two hardpoints, each with a load capacity of 150 kg (330 lb). The hardpoints can carry two RL 128-02 128 mm (HVAR-5) rockets, two 57 mm rocket launchers holding 12 rockets, two 120 kg bombs, or four 50 kg bombs. Alternatively, they can mount two MAC-AA-52 gun pods containing 7.62 mm machine guns, two 100 kg capacity cargo containers, or two auxiliary drop tanks.
