NTSB narrative
The pilot elected to make an unscheduled landing due to what he perceived as a low fuel state, as both fuel gages were indicating less than one-quarter full. While maneuvering in the traffic pattern to afford another airplane on the runway adequate time to depart, the airplane's engine began to run rough, then lost power completely. The pilot went through the checklist to restart the airplane, and nearing the end of the runway power was restored, but only briefly; the engine failed a second time and there was no attempt to restart it. A clearing was located in which to land and after touching down and rolling out, the nose gear impacted a berm, which resulted in the nose gear failing aft causing substantial damage to the firewall. During the recovery process approximately one quart of fuel was observed in the right tank and 5.5 gallons in the left tank; the fuel selector was positioned in the LEFT TANK position. The pilot said he thought the fuel selector was in the Right Tank position prior to the engine quitting, however, couldn't say for sure if he moved it to the LEFT TANK position when the engine quit. A post accident examination revealed no preimpact failures or malfunctions which would have precluded normal operation.
Probable cause
A loss of engine power due to the pilot's inadequate planning/decision and improper fuel management, which resulted in fuel starvation. A contributing factor was the berm.

- 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.
