     The Interstate Aviation Committee has completed the investigation of the accident with Mi-8T RA-24506 helicopter owned by "Airline ALROSA", CJSC occurred in the Republic of Sakha (Yakutia, RF) on October 14, 2014.
      The accident with Mi-8T RA-24506 helicopter was due to the landing and piloting technique errors during overweight landing at the ground selected from air. Landing was performed by the PIC who most probably was intoxicated by alcohol.
      The contributing factors were:

      - unsatisfactory work of medical assistant of Polyarny a/p with regard to providing the air traffic controller (briefing officer) with information about PIC's suspended from flying duties; 
      - failure by acting the deputy leader to ground the helicopter after receiving information about PIC's alcohol intoxication;
      - flight safety control system non-operability in the airline that made the helicopter departure and the task performance by the PIC not authorized for flight possible.
      - not taking the appropriate measures by the other crew members to prevent the operation;
      The exceeding of maximum allowable take-off mass of the helicopter became possible due to the issuance of the transmittal documents for the flight without real weighting of load onboard.

       The appropriate safety recommendations based on the investigation results were developed.
