What happened
During a flight segment traveling from Daraut-Kurgan toward Osh, an unspecified single-engine aircraft encountered severe weather characterized by heavy rain and thunderstorms. While operating on the leg between Dzhargital and Osh, the crew chose to proceed despite conditions falling below established minimums rather than returning to their previous location.
As a result of the inclement weather, the flight crew lost navigational orientation, causing the aircraft to drift approximately 10 km west of its intended course. The aircraft subsequently struck a steep mountain slope at an altitude of 4,000 metres. The impact occurred near a peak measuring 4,170 metres, situated roughly 15 km southwest of Sufi-Kurgan. Search teams located the wreckage two days after the incident. There were 14 fatalities and no survivors.
Findings
Investigations determined that the primary factor in the accident was the crew's decision to continue flight operations into adverse weather conditions. This choice led to a controlled flight into terrain.
