The crew departed Kharkiv to ferry the airplane to its base in Tiflis with an intermediate stop in Mineralnye Vody. After takeoff from Mineralnye Vody Airport, the crew climbed to an altitude of 300-350 metres then continued to the southeast, following the railway track. About 20 minutes into the flight, weather conditions worsened and the visibility was poor due to fog. Rather than returning to Mineralnye Vody, the captain decided to continue and reduced his altitude. He continued vertical to the railway line, sometimes to its left sometimes to its right. Too low, the airplane struck the ground and crashed near the Apollonskaya Station in Novopavlovsk. One mechanic was seriously injured while both other occupants were killed.
