NTSB narrative
The pilot encountered a tailwind during landing; the airplane overran the runway and collided with a fence. While on the final approach segment of the pilot's landing pattern, he closed the throttle. The airplane touched down about 2,000 feet down the 4,125-foot runway with a higher than normal airspeed. The pilot retracted the flaps and began to apply the brakes. The airplane skidded down the runway until impacting a fence. The pilot noted no mechanical malfunctions with the airplane prior to the accident. A preceding airplane in the pattern had advised the control tower of encountering a 10-knot tailwind. The pilot said he heard this broadcast.
Probable cause
the pilot misjudged the airplane's distance/speed which resulted in an overrun. A contributing factor was the tailwind.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2004-07-13.
