NTSB narrative
The pilot reported that, during approach to land, he corrected for a left crosswind. After crossing the threshold, he reduced power and as the airplane was about to touch down, it "rolled" left, and the left wing struck the runway. He added that the airplane immediately "righted itself" and that he then landed it.
The airplane sustained substantial damage to the left wing.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The airport's automated weather observation station reported that, about 36 minutes before the accident, the wind was from 210° at 11 knots, gusting to 19 knots. The same automated station reported that, about 24 minutes after the accident, the wind was from 210° at 17 knots, gusting to 25 knots, with a peak wind reported 3 minutes after the accident from 220° at 27 knots. The pilot landed the airplane on runway 21.
Probable cause
The pilot's failure to maintain lateral control during landing in gusting wind conditions, which resulted in the left wing striking the ground.

- 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.
