Probable cause

The pilot misjudged his speed and distance while landing, which resulted in an overrun and subsequent collision with terrain.

NTSB narrative

The pilot reported that he landed approximately a third of the way down the runway. He said that as he applied the brakes near the turnabout area at the south end of the runway, he discovered that he couldn't stop. The airplane subsequently went down an embankment, struck terrain, and sustained substantial damage. Postaccident examination of the wreckage revealed that the brake master cylinder piston rod's clevis had separated. An NTSB materials laboratory examination indicated that the separation was consistent with bending forces associated with the accident and no preexisting anomalies were detected.

Analysis
