Accident Narrative

During the landing rollout, the airplane veered off the left side of the runway and struck trees. The pilot stated that the flight and landing were uneventful until he applied brake pressure and found that the right brake had no pressure. He attempted to abort the landing roll but ran out of runway. Near the end of the runway, the pilot again applied brake pressure and the airplane veered off the left side of the runway, impacting trees.

Post-Accident Investigation

A Federal Aviation Administration (FAA) inspector responded to the accident site along with a mechanic, and they tested the brake system. According to the inspector, the brakes had equal pressure, but both were spongy and, when depressed, went to their stops. No leaks were noted in the brake system. According to the pilot, the last annual inspection took place in May 2005, and no anomalies with the airplane were noted since that inspection.
