The pilot of the PA-22-160 overflew the airport in preparation for landing, and observed the windsock, which he reported was "flat." He entered the traffic pattern for runway 17 on the downwind leg, trimmed the airplane for 80 miles per hour (mph), and added one notch of flaps. Runway 17 was 2,500 feet long, 200 feet wide, and consisted of turf. The pilot maintained 70 mph on final approach, and as the airplane touched down on the runway, he immediately applied the brakes and the airplane began to skid. As the airplane approached a fence at the end of the runway, the pilot steered the airplane off the right side. During the turn, the nose gear collapsed, the airplane ground looped, and then flipped over. The pilot reported 264 total hours of flight experience, 123 of which were in the accident airplane make and model. He also reported no mechanical deficiencies with the airplane. According to both of the passengers, the pilot landed "too fast" and with a tailwind. The winds reported at the nearest airport, 19 miles to the south, were from 260 degrees at 11 knots.
