Analysis

The acft lost power en route to spray crops & crash landed in a wooded area. The acft had flown only 2 miles when the power loss occurred. During the post accident investigation an exam of the powerplant & systems revealed that the supercharger had a loose impeller shaft and that the impeller had contacted the housing (case). The impeller case had lost metal in the contact area and the impeller outside diameter was reduced by aprx 1/4 inch. The superchargershaft bearing were worn & loose which allowed the shaft to make contact with its housing. An a m or d report was submitted by russell acft to the FAA.
