The UTVA-66, is a STOL light utility / liaison aircraft produced in the former Yugoslavia. A development of the UTVA-60, it first flew in 1966 and was intended largely for use by the Yugoslav military.^[1]

The aircraft was designed to operate from unprepared fields. Its STOL characteristics include leading edge fixed slats, flaps and drooping ailerons. The cockpit is equipped with dual flight controls. The right front and rear seats in the older version of the aircraft could be removed to accommodate two stretchers. The 66H ("Hidro") variant replaced the fixed landing gear with pontoon floats for operation from bodies of water; these could be exchanged for snow skis.

130 UTVA-66 aircraft were manufactured. The last operational aircraft were withdrawn from military service in 1999.

Subsequently, a number were sold to Canada and the United States of America where they were converted for civilian use as rugged utility aircraft.
