Accident Overview
A single-engine aircraft impacted trees shortly after takeoff, entered a stall, and subsequently crashed. The fate of the occupant remains undetermined.
Flight Details
The flight was en route from Novokuznetsk to Gorno-Altaysk and Aktash, carrying a few geologists. The departure took place from an elevation of 1,470 meters, with an outside air temperature of +30°C. At the time of the accident, the total weight of the aircraft exceeded its maximum takeoff weight (MTOW) by 358 kilograms, and the takeoff speed was recorded as too low.
Investigation and Findings
The investigation identified several contributing factors: the aircraft's weight being 358 kg above the MTOW, an insufficient takeoff speed, high-altitude density conditions, and a high outside air temperature of +30°C. These elements combined led to the aircraft's inability to gain sufficient altitude after departure, resulting in the collision with trees and the subsequent stall and crash.
