On August 18, 1997, about 0900 central daylight time, a Cessna 182Q, N86TC, registered to the TCM Flying Club, Inc., was substantially damaged while landing at the Butler-Choctaw County Airport, Butler, Alabama. Visual meteorological conditions prevailed at the time and a VFR flight plan was filed and activated for the 14 CFR Part 91 personal flight. The private-rated pilot, the sole occupant, was not injured. The flight originated about 0600, from the Kentucky Dam State Park Airport, Gilbertsville, Kentucky. The pilot stated that he diverted from the planned destination due to physiological needs. While on final approach with the flaps fully extended and with no wind, he flared for landing. The airplane floated, touched down slightly to the left of the runway centerline then bounced and touched down on the right main landing gear. He momentarily applied power and right rudder but the airplane continued off the left side of the runway. He reduced the throttle, applied right rudder and the brakes, but he was unable to stop the airplane before a collision with cleared brush. The airplane then nosed over. Examination of the runway revealed a mark made by the right main landing gear tire to the left of the runway centerline. The mark continues in an arc to the left toward the left side of the runway then just before the runway edge, a mark from the left main landing gear tire is observed. Marks were noted in the grass from the left and right main landing gears.
