Analysis

The non-type rated FAA flight test engineer executed a visual approach and was observed to be erratic and flying at v-ref when he chopped the power at 50 ft AGL and the aircraft landed hard. The instructor pilot then took control of the aircraft and executed a go-around. After flight to the final destination minor damage was found on post flight inspection.
