The airplane landed at 04:50 at Karaganda Airport and took off after refueling at 05:36. After climbing to a height of 150 meters the crew changed course to 285░. Six minutes after takeoff the crew radioed that the nr.1 engine had failed and that they were returning to the airport. Permission was given for a 30░ straight in approach and landing. While manoeuvring back to the airport, the crew had to change course because of a 67 m high building in the area. They overshot the extended centreline of the runway and attempted to turn for finals. The aircraft lost speed when the pilot turned left (in the direction of the non-working engine) while simultaneously lowering the landing gear. Control was lost and the aircraft spiralled down from a height of some 50-70 metres and impacted terrain.
