Analysis

The plt and his brother were on a long cross country flt, through mountainous terrain. After one hour of flt and while flying at 8,000 feet the plt noticed a change in engine noise and the acft had a partial power loss. The plt elected to autorotate to a snow covered surface. The touchdown was on a steep slope and the helicopter slid downslope and struck trees. Post accident investigation showed one magneto not operating properly.
