On August 15,1998, at 1025 central daylight time, a Piper PA-22-150, N9721D, collided with the ground and collapsed the landing gear, at a private airstrip near Paris, Tennessee. The personal flight operated under the provisions of Title 14 CFR Part 91 with no flight plan filed. Weather data from the nearest reporting facility revealed that visual weather conditions prevailed at the time of the accident. The private pilot received minor injuries. Examination of the airplane at the accident site disclosed that the airframe had sustained substantial damage. According to the pilot, the flight departed Camden, Tennessee, at 1000. The pilot stated that he had conducted a visual over flight of the airport to determine the direction of the landing runway and general airstrip condition. The pilot established an approach for runway 27. According to the pilot, "it seemed that I was too high, so I dropped the flaps. My descent was uncontrolled and I hit the strip very hard". The nose gear and the left main landing gear collapsed after the airplane touched down about 400 feet from the approach end of the sod runway. The pilot stated that there were no known mechanical problems with the airplane.
