Circumstances:
Following several crop spraying flights during the day, the pilot elected to make a test flight with a mechanic before the aircraft would be transferred to Kotelnikovo. After takeoff, the pilot continued at a height of about 100-150 metres then completed some turns before the aircraft started to descent. While turning at an angle of 40-45°, the airplane lost height and crashed nose first. Both occupants were seriously injured and the pilot died from his injuries less than an hour later.
Probable cause:
The pilot initiated an unauthorized test flight and completed sharp turns at a too low altitude and insufficient speed, causing the aircraft to stall and crash.
