The Interstate Aviation Committee Investigation team has completed the investigation of the accident with Mi-8Т RA-22343 helicopter operated by "UTair" Airlines occurred in the Omsk region (RF) on November 17, 2012. The accident with Mi-8Т RA-22343 helicopter was caused by the crew erroneous actions during approach resulted in anti-torque rotor entering vortex ring mode and uncontrolled helicopter left-hand rotation.

FOM limitations were violated in allowable right cross wind, due to addition of wind speed to hovering helicopter controlled movement.
Appropriate safety recommendations based on the investigation results were developed.
