Aircraft Accident/Incident Report

Salt Lake City, Utah 84112
Saturday, April 12, 2008 10:10 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot made a normal landing on runway 16 in his amateur-built experimental airplane. The pilot reported that the airplane's left brake became dysfunctional during rollout, and he was unable to stop before reaching the runway's departure end. The airplane rolled over the runway's end, entered a ditch and nosed over. The airplane had decelerated to about 10 miles per hour when it exited the runway. An examination of the airplane's brake system revealed that the left side master brake cylinder had failed.

NTSB Probable Cause Narrative

The failure of the left side master brake cylinder that led to a loss of braking capability during landing rollout. A contributing factor was the presence of a ditch next to the runway's end.
