NTSB narrative
The private pilot stated that, about 20 to 25 minutes after departure for the cross-country flight, the engine's oil temperature gauge was indicating that the oil temperature was hotter than normal. He added that, to avoid having the engine seize while in flight, he chose to perform a precautionary landing on a dirt road that had an uphill gradient. After touchdown, the airplane bounced, the right main landing gear sheared off, and the airplane turned 180° and came to rest with the right wingtip on the ground.
Postaccident examination of the engine revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation. The engine was successfully started and run for over 5 minutes at various power settings.
The tailwheel could not be manually rotated counterclockwise to the stop because the right control cable was catching and rubbing on a displaced fairing behind the pedals. It could not be determined if this had occurred before the accident and the pilot was unable to maintain directional control or was a result of the accident sequence.
Probable cause
The pilot's failure to maintain directional control during an off-airport precautionary landing on a dirt road with an uphill gradient.

- 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.
