     The Investigation team of the Interstate Aviation Committee has completed the investigation of the accident with helicopter R-66 RA-1588G owned by "Tehnodrom" LLC occurred in the Krasnodar region (RF) on June 28, 2014.
      Most probably, the fatal accident with helicopter R-66 RA-1588G was caused by the PIC's violent maneuver (inadequate pilot's operations by the throttle control twist grip) entering clouds (the pilot didn't have clearance for IFR flights) that resulted in aircraft penetration in unusual attitude and below-G conditions, impacts of pitch articulation on the main gear shaft stops - known as "bumping" and helicopter breakup in the air.   
      The contributing factor was pilot's timely indecision to return to the departure aerodrome or landing at the selected ground in the conditions of weather deterioration up to below specified values.
    
The appropriate safety recommendations based on the investigation results were developed.
