     The Investigation team of the Interstate Aviation Committee has completed the investigation of the accident with "Sky Master" RA-0862G single-built private aircraft occurred in the Moscow region (RF) on April 30, 2014.
     The accident with "Sky Master" (FVSP) RA-0862G aircraft was caused by its collision with trees at the fringe of the forest in the proximity to the RWY threshold during emergency landing with dead engine that resulted in the speed and control loss and further aircraft ground impact.
      The most probable cause of the engine failure was shutting off fuel through the main nozzle of the right carburetor by a rubber fragment which origin is not identified.
      PIC's actions during operation, occurrence and development of emergency situation were aimed at keeping the crew life but they didn't fully comply with the situation as turning for 180° in those conditions didn't guarantee safe return to the aerodrome. In conditions of the rapid situation development and time pressure for taking decision the PIC didn't activate installed at the aircraft parachute system which could probably reduce the accident severity.
      The following factors most probably contributed to the fatal accident:
      • low altitude (about 60-70 m) of the engine failure after take-off excluding safe emergency landing without turnout to prevent aircraft collision with obstacles;
      • tailwind component during the first phase (and quartering tailwind during the second phase) of reverse turn to perform emergency landing that increased turning ground-speed and its radius;
      • high obstacles in approach area and close proximity (50-100 m) of "Vihrevo" landing ground from the RWY threshold hampering safe take-off and landing of aircraft.
      The appropriate safety recommendations based on the investigation results were developed.
