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
[edit]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.[1] Testing was successful,[2] but the aircraft was redesigned for production, with a more powerful Lycoming O-480 engine, and designated the UTVA-60.[1]
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,[3] while the agricultural version's wing was fitted with slots.[1]
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.[4]
Operational history
[edit]As well as civil use, the UTVA-60 was used by the Yugoslav Air Force, who received about 35, using them until 1982,[5] while Cambodia received four aircraft.[6][7]
