Incident
Three pilots and a passenger departed Shelopugino at 1807 local time on an unauthorized local flight. After takeoff, the pilot-in-command followed the Turov River at an altitude of 100 to 150 meters when he initiated hazardous maneuvers. The airplane climbed and adopted a high nose-up attitude, then stalled, plunged into the earth, and crashed in a vertical (90-degree angle) attitude about 10 kilometers south of Shelopugino. The aircraft was totally destroyed upon impact, and all four occupants were killed.
Investigation
The official investigation determined the probable cause. The pilot-in-command was intoxicated, as were the pilot supervisor and the passenger. The copilot was not intoxicated. Analysis revealed a blood alcohol level of 2.3‰ in the pilot-in-command, 1‰ in the pilot supervisor, and 1.2‰ in the passenger.
