## Probable cause

The pilot's long landing and failure to stop the airplane on the runway, resulting in an overrun, impact with a fence, and substantial damage to the airplane.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Analysis

In a telephone interview with the NTSB Investigator-in-charge (IIC), the pilot stated that the airplane touched down midfield, and he knew he was going to overrun the runway. He attempted to abort the landing, however the airplane over ran the runway and impacted the airport perimeter fence. A postaccident examination revealed substantial damage to the fuselage. According to the pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. After multiple requests, the pilot did not return the National Transportation Safety Board Form 6120.1 Pilot/Operator Aircraft Accident/Incident Report as requested.
