What happened
During a flight originating from Petropavlovsk-Kamchatsky Airport, the crew initiated their descent toward Klyuchi Airport. As the aircraft approached the destination, the flight crew encountered weather conditions characterized by heavy snowfall, which reduced visibility to levels below established minimums.
While performing the final approach, the aircraft type (unspecified) descended beneath the glide path. The plane subsequently collided with treetops before crashing within a forested region. The accident resulted in the deaths of 35 people, including all 6 crew members and 29 passengers (identified as conscripts). Two passengers survived the impact.
Findings
Official investigations concluded that the primary factor in the accident was an incorrect approach configuration maintained by the flight crew during the descent.
