Incident Overview
A copilot, acting as the sole occupant, made the decision to undertake an illegal survey flight intended for crop spraying operations in the vicinity of Kholodnyy Klyuch. The flight was unauthorized and conducted without proper clearance.
Flight Progression
En route to the survey area, the aircraft encountered low-lying patches of fog. The presence of fog led to the pilot experiencing spatial disorientation, a condition where the pilot's perception of position and motion becomes impaired.
Loss of Control
As a consequence of the spatial disorientation, the pilot lost control of the aircraft. The aircraft then descended uncontrollably and impacted the ground.
Aftermath
The pilot sustained minor injuries as a result of the crash. The aircraft itself was damaged beyond repair, indicating that it was completely destroyed and not salvageable.
Probable Cause
According to the official accident investigation, the probable cause was determined to be a loss of control after the pilot suffered spatial disorientation while flying in foggy conditions.
