Analysis

The plt added fuel and chemicals for a total of about 230 gallons of cargo. The temperature was 87 degrees and the arpt elevation is 1100 ft. the density alt was not computed and performance not assessed. After takeoff in a crosswind turn the acft 'quit flying'. The plt said he 'added power' and dumped the load but hit a power line with the tailwheel. The acft bounced and nosed over. The actual impact was on a downwind heading as he was turning 180 degrees to spray a field just adjacent to the airptrip. The plt made no recommendations for prevention of further accidents of this type.
