At the conclusion of an aerobatic flight, the pilot intended to practice a number of circuits and landings. Two touch-and-go landings were completed, and the pilot positioned the aircraft for a full-stop landing in 10 knot crosswind conditions. Towards the end of the landing roll, the aircraft commenced to ground loop to the left. The pilot applied corrective rudder and brake, but was unable to arrest the swing. He then applied full power, with the intention of becoming airborne and passing between trees which lined the side of the strip. The aircraft lifted off, but then collided with a tree, fell to the ground, and came to rest inverted. The particular type is known to be difficult to control directionally. It was considered possible that the pilot had relaxed his concentration after the aircraft had touched down.
