On August 24, 2003, at 1930 central daylight time, a Cessna 182, N5360B, piloted by a commercial pilot, sustained substantial damage when it nosed over while landing on runway 36 (2,500 feet by 60 feet, turf/gravel) at the Cady Aerial Airport (0IS3), Deer Grove, Illinois. Visual meteorological conditions prevailed at the time of the accident. The business flight was operating under the provisions of 14 CFR Part 91 without a flight plan. The pilot reported minor injuries. The flight departed Whiteside County Airport (SQI), Sterling, Illinois, at 1840. According to the pilot's written statement, the purpose of the flight was to release four parachute jumpers at 11,000 feet above mean sea level (msl) and then refuel at 0IS3. The pilot reported that while en route to 0IS3 he monitored the SQI automated weather observing system (AWOS) and the winds were "230 [degrees true] at 3 knots." The pilot stated, "I decided I would use either end of [the] runway since [the] wind was calm." The pilot reported he elected to land on runway 36 and extended his downwind to "loose altitude." The pilot stated that on final approach the airplane was "too high" and he "tried to side slip in." The pilot reported the airspeed on final approach was "too high" and the airplane "floated down the runway." The airplane landed approximately halfway down the runway, overran the end of the runway, and nosed over. The pilot stated the accident could have been prevented if he had performed a go-around. The pilot reported the airplane had no mechanical malfunctions or failures during the accident flight. The SQI AWOS, located approximately five nautical miles north of 0IS3, recorded the following information at 1935: Wind 220 degrees true at 4 knots; 9 statute mile visibility; sky clear; temperature 28 degrees Celsius; dew point of 19 degrees Celsius; altimeter 29.99 inches of mercury.
