Of the three museum Yak-18s, this is the only one with a military background. It was built in 1954 and delivered to the Oficerska Szkoła Lotnicza nr 4 at Dęblin in June 1955. In late 1960 it became SP-BRI with the Kraków aeroclub (where the other two have flown as well) and in 1972 it was given to the museum. Repainted as shown in 2005.
