Analysis

The acft lost pwr during normal cruise. The plt attempted to autorotate into a clearing in the trees. Post accident exam discovered an air leak in the fuel control. The pressure compressor discharge (pcd) line 'b' nut was disconnected from the fuel control. This caused the eng to reduce pwr to flt idle.
