Circumstances:
The right main landing gear downlock pin retracted just before or during touchdown. The airplane touched down 21 feet short of the runway. It traveled that 21 feet, traveled the full length of the 6999- foot runway, then traveled another one-fourth of a mile and stopped on a golf course. No pre-touchdown mechanical, hydraulic or electrical problems could be found. All four occupants escaped uninjured.
