The pilot had landed at the 800 metre long strip previously. The strip had an uphill slope to the west. When he arrived in the circuit area the pilot said the windsock indicated a 10 - 12 knot easterly and he noted another aircraft landing into the west. Taking into consideration the landing direction of the other aircraft and the uphill slope, the pilot decided to land into the west. The aircraft touched down about half way along the strip. The pilot considered that the aircraft would not stop in the remaining distance so he applied full power to go around. The aircraft just cleared a fence at the end of the strip but then descended and struck a second fence about 190 metres further on. It then veered left and eventually came to a stop some 400 metres beyond the end of the strip.
