NTSB narrative
The airplane contacted the terrain during an aborted landing. The pilot reported there was an 11 knot crosswind with gusts to 15 knots while he was landing on runway 17. He reported he used one notch of flaps and was lined with the runway on final approach. The pilot reported the airplane was a little fast and he let it float until it touched down for a smooth landing. He reported that a second later the right wing lifted and the airplane turned to the left. The wing came back down and he attempted to straighten out the heading, but was unable to so he decided to add power to go around. The pilot reported the landing gear contacted two to three foot tall weeds off the end of the runway which resulted in landing gear damage with the right landing gear being pushed up through the top of the right wing. Winds reported at the accident airport about 40 minutes prior to the accident were from 210 degrees at 7 knots, gusting to 16 knots.
Probable cause
The delay in initiating the aborted landing which resulted in inadequate altitude to clear high vegetation off the end of the runway. Factors associated with the accident were the gusty crosswind, inadequate compensation for the wind conditions, and the high 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, coordinates. 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.
