     The Investigation team of the Interstate Aviation Committee has completed the investigation of the accident with Mi-8 RA-24255 helicopter owned by NPK "PANH" JSC which occurred in the Krasnodar Territory (RF) on September 4, 2014.
     The accident was caused by the rotorcraft penetration in vortex ring state during helicopter-type landing without ground effect. The crew didn't try to recover by the method specified in FOM of Mi-8T helicopter.
     Penetration in vortex ring state was due to PIC's failure during final maneuver (rearward flight at 40 km/h) which is not described in the helicopter FOM and wasn't trained by the crew.
     The appropriate safety recommendations based on the investigation results were developed.
