Probable cause

The pilot experiencing spatial disorientation and the resultant excessive descent rate. Factors were: the dark night conditions.

Analysis

The pilot was cleared by ARTCC for a visual approach to runway 24. He advised UNICOM he was too high and would circle to land. An airport attendant saw the airplane's landing lights and watched it begin a left turn when it was over and halfway down the runway. The descent rate increased to a 'hard dive about 35 to 45 degrees' before disappearing into a ravine one mile south of the airport. Visual conditions prevailed but it was a dark night with no moon.
