The **Utva C-3 *Trojka*** (Trey) was a light aircraft built in Yugoslavia shortly after World War II as a result of a government competition to develop a new, domestically built aircraft with which to equip the country's flying clubs. The winning design was submitted by [Boris Cijan](https://en.wikipedia.org/w/index.php?title=Boris_Cijan&action=edit&redlink=1) and [Djordje T. Petković](https://en.wikipedia.org/w/index.php?title=Djordje_T._Petkovi%C4%87&action=edit&redlink=1) and the prototype was built by [Ikarus](/source/Ikarbus) as the **Ikarus 251**. Series production took place at [Utva](/source/Utva) as the **C-3**. It was a conventional, low-wing cantilever monoplane with fixed tailwheel undercarriage. The pilot and instructor sat side by side under an expansive canopy. The type remained in production until the mid-1950s with later examples powered by the more powerful [Walter Mikron](/source/Walter_Mikron) 4.
