The '''Utva-65 Privrednik''' ('''Merchant''') is a Yugoslav civil aircraft designed and used for agricultural work.<ref>{{Cite web|url=http://www.vazduhoplovnetradicijesrbije.rs/index.php/clanak/128-utva-65|title=Утва 65 Привредник|access-date=2013-05-08|archive-date=2016-08-17|archive-url=https://web.archive.org/web/20160817214947/http://www.vazduhoplovnetradicijesrbije.rs/index.php/clanak/128-utva-65|url-status=dead}}</ref>

==Design and development== The Utva-65 was designed specifically as an agricultural aircraft. It was a single-seat, low-wing braced monoplane with a single engine.<ref>{{cite journal | url = http://www.flightglobal.com/pdfarchive/view/1965/1965%20-%201670.html | type = PDF | title = Sport and Business | journal = Flight International | page = 902 | date = 10 June 1965 | publisher = Reed Business Information | access-date = 29 January 2011 | issn = 0015-3710 }}</ref> The wings were essentially identical to those of the high-wing UTVA-60 apart from the wing roots, which were extended and strengthened so that the chord was greater and the wingspan increased by {{convert|0.82|m|ft}}<ref name="JAWA66">{{Harvnb|Taylor|1966|pages=367}}</ref> These wings were of single-spar, all-metal construction, carrying ailerons that linked to the flaps, drooping 15 degrees when the flaps were set to 40 degrees. A single streamlined strut ran from the upper fuselage to mid-wing on either side, with minor struts from them to the wing at about one-quarter span. The conventional all-metal tail surfaces were also from the UTVA-60, but had increased elevator area.<ref name="JAWA66"/>

The fuselage of the Utva-65 had a steel-tube structure, with metal skinning forward and below and fabric elsewhere.<ref name="JAWA66"/> The single-seat pilot's cockpit was high and behind the trailing edge; combined with all-round glazing, this gave a good view and also increased fuselage space. There was a {{convert|0.75|m3|cuft|adj=on|sp=us}} hopper for fertilizer, spray, etc. ahead of the cockpit.<ref>{{Harvnb|Green|1966|pages=250–1}}</ref> Standard spray bars could be fitted under the trailing edge. The undercarriage was of the conventional tailwheel kind, with cantilever main legs angling outwards from the wing root.

At launch there were three choices of engine, all Lycoming six-cylinder horizontally-opposed air-cooled types. The GO-480-B1A6 produced 270&nbsp;hp (200&nbsp;kW), the geared GO-480-G1A6 290&nbsp;hp (216&nbsp;kW), and the IGO-540-B1A 350&nbsp;hp (260&nbsp;kW).<ref name="JAWA66"/> A later variant of the Utva-65, the '''Utva-67''' (first flown in 1967), was similar, but had the eight-cylinder, 400{{nbhyph}}hp (298&nbsp;kW) Lycoming IO-720-A1A and a revised fuselage of greater capacity. Its top speed was {{convert|295|km/h|mph|abbr=on}}.

==Operational history== The Utva-65 was used in Yugoslavia by agricultural cooperatives for pesticide application and mosquito control. The Algerian airline Societé de Travail Aérien began operations in October 1968 using five Utva-65 aircraft for similar work.<ref>{{cite journal | url = http://www.flightglobal.com/pdfarchive/view/1971/1971%20-%200733.html | type = PDF | journal = Flight International | date = 4 May 1971 | page = 644 | title = World Airlines | issn = 0015-3710 | access-date = 29 January 2011 | publisher = Reed Business Information }}</ref>
