At that time the aircraft was over Karakuzhur valley. Given the limited thrust available and the high mountains in the area, the flight could not reach Naryn. The captain new a small airstrip in the valley that was used for agricultural operations. He had flown An-2 aircraft from the airstrip, which was located at 2700 m above sea level. The unprepared strip was now covered with rocks (larger than 40 cm). Also irrigation ditches were present and there was a ravine near the strip.
The airplane carried out an emergency landing on the airstrip and caught fire.
