NTSB narrative
The pilot of the tailwheel-equipped airplane reported that, during the second flight of the day, which was a 3 hour 30 minute flight, the tower controller at the destination airport instructed him to land on runway 35. During the landing roll, he lost directional control, the airplane ground looped to the right, and the left wing impacted the ground.
The pilot added that he believed the accident was the result of fatigue. He added that he should have requested runway 13, which would have reduced the crosswind component, rather than accept the assigned runway.
The airplane sustained substantial damage to the left wing and left aileron.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The automated weather observation station at the airport reported that, about 37 minutes before the accident, the wind was from 100° at 12 knots. The same automated station reported that, about 23 minutes after the accident, the wind was from 100° at 12 knots, gusting to 22 knots. The airplane landed on runway 35.
Probable cause
The pilot’s failure to maintain directional control during the landing roll in tailwind and crosswind conditions. Contributing to the accident was the pilot’s fatigue.

- 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.
