      The Investigation team of the Interstate Aviation Committee has completed the investigation of the accident with Mi-8Т RA-24410 helicopter owned by "Angara" Airlines" JSC occurred in the Irkutsk Region on 6 May 2013. 
      The accident with Mi-8Т RA-24410 helicopter occured during aviation works (blasting operations) on elimination of ice-jams at water lines in emergency situation conditions was caused by the lack of clear regulations regarding the procedure of preparation and implementation of such activities as well as promotion of safety during transportation and usage of dangerous goods that resulted in helicopter airburst. 
      Most probably the helicopter airburst was caused by "donor charge" (ready-use charge with beaded capsule-detonator) mishandling by somebody in passenger-cargo helicopter cabine. Apart from the blasting crew three service passengers two of whom didn't have any pactice, skills and authorization to handle the explosives were in passenger-cargo cabin.
      The appropriate safety recommendations based on the investigation results were developed.
