On August 18, 1999, at 1000 central daylight time (cdt), a Piper PA-34-220T, N300JV, piloted by a commercial pilot, was substantially damaged when its right main landing gear collapsed during a high speed turn to the left after departing the departure end of runway 17 (3,000 feet by 60 feet, dry asphalt), striking a runway end identifier light, and skidding sideways on the grass next to the runway end at the Salem Memorial Airport (K33), Salem, Missouri. Visual meteorological conditions prevailed at the time of the accident. The personal flight was operating under the provisions of 14 CFR Part 91, and was not operating on a flight plan. The pilot and passenger reported no injuries. The flight departed the Columbia Regional Airport, Columbia, Missouri, at 0930 cdt. The pilot said the airplane "...landed long, went off the end of the runway and collapsed the right main gear." A Federal Aviation Administration Principal Maintenance Inspector (PMI) conducted the on-scene investigation. The PMI said the pilot had used runway 17 at K33. The PMI reported the pilot said "...the aircraft floated during the flair, causing a long landing." The PMI reported that N300JV had made 1,300 feet of tire skid marks with both main landing gear tires. The skid marks were curved to the left as they went beyond the runway's end. The airplane stopped its skid on the runway's grass clearway area about 20 feet north of the runway end. The taxiway for runway 35 is on the left side of the runway at its end. The closest weather to the Salem Memorial Airport is at the U.S. Army's Forney Field, Fort Leonardwood, Missouri. This airport is about 30 miles west of the accident airport. At 0955 cdt, Forney Field was reporting variable winds at 5 knots. The air temperature at Forney Field was reported to be 86 degrees Fahrenheit. A second airport, Rolla National, Rolla, Missouri, located about 40 miles north of the accident airport reported surface winds were 7 knots from 190 degrees at 0953 cdt. The air temperature was reported to be 84 degrees Fahrenheit.
