The pilot reported that he had made an approach to land on runway 32. During the landing roll the pilot became concerned that the aircraft would not stop before the end of the runway and he decided to go around for another circuit. The pilot applied power and attempted to fly the aircraft off the ground at the end of the runway. The aircraft did not climb and the right wing collided with a three metre high tree causing the aircraft to slew around and touch down again. The right wing, engine cowl and nosewheel were also damaged as the aircraft came to a stop, still on its landing gear and pointing in the opposite direction to the landing, approximately 70 m from the end of the strip. It is probable that the pilot flew the aircraft off the ground at too low an airspeed and the combination of the low airspeed and its associated drag prevented the aircraft from climbing clear of the obstacles.
