Probable cause

The pilot's poor planning/decision. Factors include selecting the wrong runway under the high density altitude conditions.

Analysis

The pilot of the Beechcraft A-36 attempted to depart from a 2,850 foot runway, with a density altitude of approximately 10,000 feet. When the aircraft had used up about 60% of the runway, the pilot decided to abort. He was unable to stop the aircraft in the remaining runway, and the aircraft went over a 20 foot drop-off, 30 feet past the end of the runway. Two other runways were available to the pilot. One was 3,250 feet, and the other was 7,020 feet long.
