NTSB narrative
The private pilot reported that he was landing his tailwheel-equipped airplane at his remote, 650-foot-long private airstrip, at the conclusion of a personal cross-country flight operated under Title 14, Code of Federal Regulations Part 91. He said that wind conditions required an easterly approach, over an area of stump-covered, down sloping terrain. During the approach, the airplane’s right main wheel struck a tree stump at the approach end of the site, and the airplane subsequently nosed over. The airplane sustained substantial damage to the wings, fuselage, and empennage. The pilot reported that there were no preaccident mechanical problems with the airplane. In his written report to the NTSB, the pilot noted that the accident might have been avoided if he had waited until wind conditions allowed for a different approach, or if he had waited to reduce engine power after clearance with the stump was ensured.
Probable cause
The pilot’s misjudged landing on a downsloping, short landing strip, resulting in a nose over.

- 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 2009-08-02.
