      The Investigation team of the Interstate Aviation Committee has completed the investigation of the accident with "Klassika" AT104 series 80TA model RA-1360G private hot-air balloon.
      The crash with "Klassika" AT104 series 80 TA model RA-1360G hot-air balloon was caused by fire in the car after its turnover during the hot-air balloon landing. 
      The hot-air balloon fire was caused by gas ignition due to pressurization leakage of the hot-air balloon thermal unit and fire in pilot burner.
      Pressurization leakage of the hot-air balloon most probably was caused by unauthorized impact on gas manifold and/or gas sleeve by passengers and/or pilot during the car turnover.   
      The following factors most probably contributed to the accident:
      - fire in pilot burner that didn't comply with hot-air balloon FOM;
      - lack of pilot's information about turbulence in landing zone;
      - installation of self-made gas manifold in the car not specified by airframe of hot-air balloon thermal unit;  
      - lack of gas mainfold protection from unauthorized impact of persons in the hot-air balloon car;
      - passengers location in the car before landing didn't comply with the hot-air balloon FOM.
      The appropriate safety recommendation based on the investigation results were developed.
