Cargo Flight from Biisk to Alma-Ata Ends in Mountain Collision (CCCP-26007)

Incident Overview and Crew Complement The aircraft was operating a cargo flight from Biisk to Alma-Ata. On board were four passengers, including a loadmaster, and five crew members. The cargo consisted of 3,600 kilograms of various goods. ## Descent and Communication Challenges Approximately 70 kilometers from the destination, air traffic control authorized the crew to descend from 6,000 meters to 3,600 meters. At that time, weather conditions were marginal, characterized by limited visibility and a low ceiling. During the descent, several radio contacts were established between air traffic control and the pilots, but most transmissions were inaudible. The crew continued the descent without knowing their exact position and without visual contact with ground obstacles. ## Impact and Aftermath At 1908 local time, the aircraft struck the slope of a mountain that is 2,370 meters high. The impact occurred 56 kilometers east of Alma-Ata Airport. The wreckage was discovered 22 meters below the summit, and all nine occupants were killed.
