During the civil war the Croatian AF took some former Yugoslav Utva 75 on strength as observation plan and light bomber. This one was once 53177 in Yugoslav service, but is only marked HZS (Hrvatske Zračne Snage = Croatian Air Force) on the fin. It has no visible serial. The registration is taken from the log book behind the wind screen.
