NTSB narrative
According to the pilot, he touched down on the runway further down than he intended. He advanced the throttle in an attempt to clear a fence at the end of the runway and abort the landing. The airplane impacted the top of the fence, crossed a road, collided with another fence, and came to rest against a building. The firewall, horizontal stabilizer, and both wings were substantially damaged. The pilot reported no preimpact mechanical failures or malfunctions of the airplane.
Probable cause
The pilot's delay in aborting the landing, which resulted in a collision with a fence.

- 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: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
