Analysis

The helicopter collided with the platform on a trailer during a practice landing. The plt was not satisfied with the acft position on the platform and in attempting to re-position the helicopter rocked and hit the tail rotor against the trailer. Lost of anti-torque control caused the acft to touch down in a downwind yaw and collapsed the right landing skid. The acft rolled over to the right and burned. The wind was from 100 degrees at 10 KTS gusting to 20 KTS.
