The UTVA-60 is a Yugoslavian light aircraft of the 1960s. First flying in 1959, it was built by UTVA for both the Yugoslavian armed forces and for civilian use.

Development and design

In 1959 the Yugoslav aircraft company UTVA designed and built a single-engined, high-winged light utility aircraft, the UTVA 56, with a prototype making the first flight on 22 April 1959. Testing was successful, but the aircraft was redesigned for production, with a more powerful Lycoming O-480 engine, and designated the UTVA-60.

The UTVA-60 is an all-metal, four-place, strut-braced high-wing monoplane. It is fitted with a fixed conventional undercarriage which uses cantilevered steel tube struts. Trailing-edge wing flaps are linked to the ailerons, drooping the ailerons when the flaps are lowered to reduce landing speed, while the agricultural version's wing was fitted with slots.

The UTVA-60 was used as the basis for the UTVA-65, a specialised agricultural aircraft, which used the wings, undercarriage and tail of the UTVA-60, but with a low-mounted wing. The UTVA-60 was replaced in production by the UTVA-66, a further improved version.

Operational history

As well as civil use, the UTVA-60 was used by the Yugoslav Air Force, who received about 35, using them until 1982, while Cambodia received four aircraft.
