The pilot was making an approach in light wind conditions to a 600 metre long strip. Undulations on the surface were such that the slope in the landing direction varied from about 7 up to 4 down. The pilot was using a short-field landing technique. Touchdown occurred just prior to the threshold, and the aircraft bounced. Full power was applied, but the aircraft then touched down heavily 100 metres in from the threshold. The noseleg broke at the fork, the propeller struck the ground several times and the aircraft came to rest at the edge of the strip. The strip did not meet the published requirements for an ALA suitable for Private category operations. The premature touchdown short of the threshold may have resulted from visual illusions associated with the strip slope. The aircraft had stalled during the attempted recovery from the bounce after initial touchdown.
