What happened
During a flight traversing the Stara Planina mountain range, an aircraft departed from its intended flight path. While navigating the mountainous terrain, the aircraft encountered powerful atmospheric disturbances that forced it off course. The flight ultimately impacted the slopes of Mt Paskal.
The accident resulted in a high number of casualties among those on board. Of the seven crew members present during the flight, six fatalities were recorded. Only one individual survived the impact, sustaining serious injuries.
Findings
Investigations into the crash determined that the primary factor leading to the loss of control was the encounter with a strong downdraft. This intense downward air current prevented the aircraft from maintaining its altitude and stability, ultimately leading to the collision with the mountain.
