Circumstances:
Six minutes after takeoff from Karaganda Airport, while climbing, the crew reported to ATC that the left engine failed and obtained the permission to return. The pilot in command completed a circuit and started a descent. On final approach, while completing a last turn to the left at a height of 60 meters, the aircraft stalled and crashed in a huge explosion in a field located short of runway threshold. The aircraft was destroyed by impact forces and all 25 occupants were killed.
Probable cause:
Investigations were unable to determine the exact cause of the failure on the left engine. However, it was reported that the crew already encountered technical problems with the same engine a day prior to the accident but failed to report these problems to the ground maintenance.
