Incident Sequence
An aircraft departed Pokrovsk on an ambulance flight bound for Sangar, with planned intermediate stops at Magan and Kobyay. During the approach to Kobyay Airport, the aircraft was too high and its speed was excessive. The captain continued the approach instead of initiating a go-around, and the aircraft touched down 375 meters past the runway threshold. The runway length is 600 meters.
Unable to stop within the remaining distance, the aircraft overran the runway, collided with various obstacles, and came to rest 50 meters beyond the runway end. The crew did not report the incident to the company and, a few minutes later, decided to take off again.
After liftoff from Kobyay Airstrip, the aircraft was unable to gain sufficient speed and height. It struck trees and crashed in snow-covered terrain, bursting into flames. The aircraft was destroyed by fire.
Injuries and Damage
All 13 occupants sustained injuries, among them five serious injuries.
Probable Cause
It was determined that the captain was intoxicated at the time of the accident and that he started the mission from Pokrovsk already drunk. He took the decision to take off from Kobyay Airstrip despite the propeller blades having been damaged during the previous overrun.
