After arriving at the strip at about 0700 hours, the pilot assembled the aircraft and inspected it before carrying out three taxiing runs along the strip. He then rechecked the aircraft before conducting a short, apparently uneventful, flight in the vicinity of the strip. After landing the pilot taxied the aircraft back to the start point and commenced another takeoff. When the aircraft became airborne it was observed to turn left and shortly afterwards the right wing struck a tree. The aircraft spun to the ground and the pilot was fatally injured by the impact forces.
