      The Investigation team of the Interstate Aviation Committee has completed the investigation of the accident with Аn-2 RA-56528 s/h private aircraft occurred in the Stavropol Territory (RF) on May 18, 2015. The need of the emergency landing was due to the engine flameout in the air most probably caused by the oil tank swelling and pressing its wall on the fuel shuttoff valve lever.
      Oil tank pressure and its swelling most probably caused carbon deposit in vent pipeline connecting oil tank with atmosphere.
      The following factors most probably contributed to the accident:
      - no water washing of the oil tank and vent pipeline of oil tank with atmosphere specified by scheduled maintenance after 400±30 flight hours or 12±1 month of operation;
      - aircraft maintenance by people not having the aircraft maintenance license;
      - flight operation over locality at the altitude insufficient to perform landing within its limits in case of aircraft nonoperation;
      - flight operation by PIC in moderate alcohol intoxication. 
      The appropriate safety recommendations based on the investigation results were developed.
