The Zlin Z-381 in Czechoslovak Air Force service was designated as the C-106 and used as a pilot trainer. This example is on display at the Letecké Muzeum Kbely in the markings it wore at the Aviation School Prostějov in the early 1950s. It then flew with the Praha Točná Aeroklub as OK-DJR and was eventually sold to a private individual before becoming part of the National Technical Museum. It was handed over to the Letecké Muzeum Kbely in 1968 andcompletely renovated before going on display.

According to Scrambles 'Military Out of Service' this is former OK-DJR with no military history. It represents a 3 LSP machine in the Czech Air Force museum.
