What happened
The aircraft was operating at a low cruising altitude when it collided with trees in a forested section of Mt Sayan. The impact caused the plane to break apart and catch fire immediately after striking the ground. Of the three people on board, two occupants lost their lives, while one passenger sustained serious injuries.
Findings
Official investigations determined that the pilot was under the influence of alcohol at the time of the accident. This impairment of judgment and coordination is cited as the primary factor leading to the loss of control and subsequent collision with terrain.
