NTSB narrative
The pilot reported that while flying over a lake he developed a severe headache and decided to land on a remote dirt area on the northwest side of the lake to rest. He overflew his intended landing site and did not see any obstructions to landing. However, he further reported that close to touch down he noticed fence posts perpendicular to his landing path and applied full power to climb over them, but was unsuccessful. The airplane impacted the posts, which resulted in substantial damage to the wings.
The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
Probable cause
The pilot's failure to see and avoid fence posts during landing, which resulted in substantial damage to the wings.

Source notes (4)
- 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. 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.
- API snapshot SHA-256: 3cc9bb0cc44be870d15ae0be8b7f1215589a9210deeea6b64290e908eb4bd5e6; retrieved 2026-09-16T04:09:30.513Z.
