NTSB narrative
The airplane was about 11 miles northeast of the airport on the approach to the runway when the engine suddenly stopped developing power. The pilot attempted to restart the engine multiple times but was unsuccessful, and he initiated a forced landing to a nearby field. Postaccident examination of the airplane revealed that the wing fuel tanks were not breached and showed little damage. During the recovery, it was noted that both wing tank fuel caps were loose from their respective fuel tank filler necks and hanging by their chains. No fuel was found within the tanks, nor was there a fuel smell around the immediate area. Fuel was noted in and drained from the fuel lines, a condition that in a carbureted engine would be inconsistent with a fuel exhaustion event. Postaccident examination of the airframe and engine revealed no anomalies that would have precluded normal operations. Serious carburetor icing at cruise power was probable during the timeframe of the accident; however, it is unclear if that contributed to the loss of power.
Probable cause
A total loss of engine power for undetermined reasons.

- 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.
