NTSB narrative
The pilot reported that he landed long on a dirt runway and realized he was running out of runway. He decided to abort the landing and applied full power as it was too late to stop the airplane. It did not accelerate as he expected due to the soft dirt. The pilot added that the airplane did not have enough airspeed to fly and while in ground effect, it struck a tree limb and cartwheeled. A post-impact fire ensued and the airplane was destroyed. The pilot stated that there were no pre impact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot’s failure to ascertain a proper touchdown point and late decision to initiate a go-around, which resulted in a subsequent collision with vegetation.

- 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, cause areas. 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.
