What happened
On the evening of the accident, an aircraft departed from Sisian Airport at 18:00 local time, heading in an easterly direction. During the cruise phase of the flight, which was being conducted at an altitude of 2,700 metres, the flight encountered deteriorating weather conditions characterized by increasing cloud cover and a significant reduction in visibility.
Despite the worsening environmental conditions, the pilot-in-command elected to proceed with the flight rather than returning to the departure airfield. While navigating through the clouds, the aircraft type struck the peak of Mt Kysyrdag, which reaches an elevation of 2,987 metres. The impact resulted in a post-crash fire that completely destroyed the airframe. The wreckage was subsequently located at an altitude of 2,750 metres.
Findings
There were two fatalities resulting from the accident, as both occupants of the aircraft perished in the crash. Investigations into the event concluded that the primary factor was the crew's decision to maintain their course into restricted visibility, which was a violation of established flight procedures regarding cloud cover and visibility limits.
