The UTVA-66, is a STOL light utility / liaison aircraft produced in the former Yugoslavia. A development of the UTVA-56, it first flew in 1966 and was intended largely for use by the Yugoslav military.[1]
Description
[edit]The UTVA-66 derived from the UTVA-56, featuring fixed leading-edge slats and a larger tail.[2]
The aircraft was designed to operate from unprepared fields. Its STOL characteristics include leading edge fixed slats, flaps and drooping ailerons.[3] 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.[citation needed] The 66H ("Hidro") variant replaced the fixed landing gear with pontoon floats for operation from bodies of water;[2] these could be exchanged for snow skis.[citation needed]
Operational usage
[edit]
130 UTVA-66 aircraft were manufactured.[citation needed]
During the Yugoslav Wars some aircraft fell into Slovenian and Croatian hands.[2] The last operational aircraft were withdrawn from military service in 1999.[citation needed]
Subsequently, a number were sold to Canada and the United States of America where they were converted for civilian use as rugged utility aircraft.[citation needed]
