Analysis

While approaching a field to dispense rice, the acft struck a set of power lines. The plt had flown over the same set of power lines for nearly 2 hours. The flagmen stated they heard the acft strike the wires and one of the wires made a 'pop' as if being separated from the pole. The remainder of the three lines stayed with the acft during the descent. The wires were lying by the acft which had flipped inverted and caught fire. An acft inspection revealed no preimpact failures of the flt controls or engine components. The transmission lines are difficult to see from the ground and air, blending with the background coloring.
