According to the pilot of the Cessna 195, during a familiarization flight with the airplane's owner, they returned to the departure airport after practicing maneuvers for approximately 1 hour to practice full stop landings. Prior to entering the traffic pattern, he announced his intentions by radio to make a go-around on the first approach to runway 32, to "check wind drift and get the landing attitude." He believed the wind was 240 degrees at 6 to 8 knots, and that it was well within his "recent tail wheel experience." After the go-around, he continued in the traffic pattern and commenced a second approach with the intention of making a full stop landing. The touchdown was "normal," with no "excessive bounce," and he maintained directional control for the first few seconds. Moments later, the airplane ground looped, departed the side of the runway, and was substantially damaged. The pilot believed that he had not "pulled the power all of the way off," and that a "greater than normal" wind shift occurred as the rudder was becoming less effective.
