Investigation Summary
The investigation revealed a systemic failure in both flight discipline and event organization. The pilots, Volodymyr Toponar and Yuriy Yegorov, were performing a complex routine that deviated from the planned flight path. Critically, the spectator zones had been moved shortly before the show without adequate notification to the crew. During a half barrel roll, the aircraft lost air speed and altitude. As the pilots attempted to recover, they found themselves heading directly toward the crowd rather than parallel to it. Despite automated warnings and visual cues that they were dangerously low, the crew continued the maneuver until the left wing clipped the ground and a parked Ilyushin Il-76MD transport plane. The resulting explosion and debris, which included a section of barbed wire fence dragged by the wreckage, caused massive casualties among the spectators.
Final Conclusions
The official investigation concluded that the primary cause was pilot error, specifically the failure to follow the flight plan and performing unauthorized maneuvers at dangerously low altitudes. Contributing factors included poor organization by the military command, a mismatch between the flight maps and the actual airfield layout, and the decision by air traffic controllers to allow the routine to continue despite safety violations. The pilots also claimed a loss of engine thrust during the final maneuver, though this was largely overshadowed by the findings of procedural negligence.

Systems & Failure Modes
K-36DM Ejection Seat
The zero-zero capable ejection system allowed both pilots to survive despite the aircraft being nearly at ground level and in a bank.
Flight Computer / Warning System
The aircraft issued automated warnings regarding low altitude and dangerous flight parameters which the pilots reportedly failed to react to in time.
