At about 300 feet on climb after take-off, the engine suffered a partial loss of power. The pilot turned the aircraft back towards the strip and shortly after aligning it for landing, the engine suffered a further loss of power. The pilot was unable to avoid power lines on the approach path and the aircraft collided with the wires before coming to rest near a house. The engine was still running when the aircraft struck the ground, and the reason for the decrease in performance could not be established.
