NTSB narrative
According to the pilot, he was approaching the airport to land when he encountered a gust of wind. The airplane collided with power lines and subsequently impacted the ground below, coming to rest inverted. The empennage was twisted and partially separated, and both wings were crushed. The pilot reported no preimpact mechanical anomalies with the airplane.
Probable cause
An in-flight collision with power lines following an encounter with a wind gust.

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: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2011-03-12.
- API snapshot SHA-256: 8848ca0bf6d32d6148a2290fd5210acd13f9c34bb668a64fa80ceef3962be4e1; retrieved 2026-09-15T15:54:31.824Z.
