NTSB narrative
The airplane owner/pilot stated that he overflew the airstrip, which was oriented northeast/southwest in hilly terrain, and saw that the windsock indicated light wind from the southwest. He entered a left traffic pattern for a landing to the northeast (downwind). When the airplane was about halfway down the airstrip, it had still not touched down, and the pilot decided to abandon the landing attempt. He applied takeoff power, pitched and trimmed for a climb, established a positive rate of climb, and retracted the flaps. The airplane did not appear to be outclimbing the rising terrain, so the pilot increased the pitch attitude in an attempt to increase the climb rate. The stall warning sounded a few times, and, each time, the pilot readjusted the pitch as necessary to silence the warning. The pilot continued to fly the runway heading because he did not want to attempt any turns and thereby risk an aerodynamic stall. The airplane impacted terrain about 1.6 miles from and about 1,000 feet above the midpoint of the airstrip. A fire, first visible on the right side of the cowling near the battery, quickly ensued, which consumed the fuselage and wings. The pilot reported that he did not experience any mechanical conditions or failures that would have precluded normal operation.
Probable cause
The pilot's delayed decision to abandon the landing attempt, which resulted in the airplane colliding with rising terrain. Contributing to the accident was the pilot's decision to land with a 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. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2012-03-12.
