Incident Overview
Minutes after departing from Chegdomyn, the aircraft's engine began to lose power and misfire. Black smoke entered the cockpit, severely limiting the pilot's visibility. The captain initially decided to return to Chegdomyn but determined that was not feasible. He then reduced altitude and attempted an emergency landing. During the landing attempt, the airplane struck trees and crashed.
Occupant Injuries
Three passengers sustained serious injuries, while nine other occupants were unharmed. Less than an hour after the accident, a young boy succumbed to his injuries.
Official Investigation Findings
The probable cause of the accident was a failure of the engine after the piston in cylinder number 1 failed in flight.
