A development of the [UTVA-56](/source/UTVA-56), it first flew in 1966 and was intended largely for use by the [Yugoslav military](/source/Yugoslav_People's_Army). ==Description== The UTVA-66 was derived from the UTVA-56, featuring fixed leading-edge slats and a larger tail.{{sfn|Rendall|1996|page=215}} The aircraft was designed to operate from unprepared fields. Its [STOL](/source/STOL) characteristics include fixed leading-edge slats, flaps and drooping ailerons. The [cockpit](/source/cockpit) is equipped with dual flight controls.{{cite web |title=About us |url=https://utva-avio.com/about-us/ |website=UTVA AVIO D.O.O. |access-date=1 June 2026}} In the ambulance version, the front right seat and rear seats 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;{{sfn|Rendall|1996|page=215}} floats could also be exchanged for skis or wheels. ==Operational usage== About 130 UTVA-66 aircraft were manufactured. During the [Yugoslav Wars](/source/Yugoslav_Wars), some aircraft fell into [Slovenia](/source/Slovenia)n and [Croatia](/source/Croatia)n hands.{{sfn|Rendall|1996|page=215}} The last examples were withdrawn from military service in 1999. A number of aircraft were exported or later appeared in civilian use outside the former Yugoslavia, including in Canada and the United States.{{cite web |title=UTVA-66 Short takeoff and landing aircraft |url=https://www.redstar.gr/en/other/world-aviation/fyrom-military-aerial-means/utva-66-short-takeoff-and-landing-aircraft.html |website=RedStar.gr |access-date=1 June 2026}} ==Variants== * '''66AM''' – Air ambulance version.{{sfn|Rendall|1996|page=215}} * '''66H''' – [Floatplane](/source/Floatplane) version.{{sfn|Rendall|1996|page=215}} * '''66V''' – Armed variant with provisions for underwing armament.{{sfn|Rendall|1996|page=215}} ==Former military operators== thumb|UTVA-66H thumb|UTVA-66 with floats ;{{flag|Bosnia and Herzegovina}} * [Army of the Republic of Bosnia and Herzegovina](/source/Army_of_the_Republic_of_Bosnia_and_Herzegovina){{sfn|Ripley|2013|page=81}} ;{{CRO}} * [Croatian Air Force](/source/Croatian_Air_Force){{sfn|Rendall|1996|page=215}} ;{{flag|North Macedonia}} * [North Macedonia Air Brigade](/source/North_Macedonia_Air_Brigade) ;{{flag|Republika Srpska}} * [Republika Srpska Air Force](/source/Republika_Srpska_Air_Force){{sfn|Ripley|2013|page=81}} ** 92nd Light Multi-role Squadron{{sfn|Ripley|2013|page=81}} ;{{SLO}} * [Slovenian Air Force](/source/Slovenian_Air_Force){{sfn|Rendall|1996|page=215}} ;{{YUG}} * [Yugoslav Air Force](/source/Yugoslav_Air_Force){{sfn|Rendall|1996|page=215}} ==Aircraft on display== ;Serbia * [Museum of Aviation (Belgrade)](/source/Museum_of_Aviation_(Belgrade)) in [Belgrade](/source/Belgrade) – a number of UTVA-66 aircraft, including the UTVA-66H, are on display.{{cite web |title=Muzej Ratnog Vazduhoplovstva |url=http://www.aviationmuseum.eu/World/Europe/Serbia/Belgrade/Muzej_Ratnog_Vazduhoplovstva.htm |website=AviationMuseum.eu |access-date=1 June 2026}} ==Specifications (UTVA-66)== {{Aircraft specs |ref=''Jane's All the World's Aircraft 1971–72''.{{Harvnb|Taylor|1971|pp=472–473}} |prime units?=met |genhide= |crew=1 |capacity=
