NTSB narrative
Shortly after takeoff, the private pilot reported to the tower controller that the airplane had experienced a "power failure" and would be returning to the airport. A witness reported that he observed the airplane flying low and trying to make a sharp turn back toward the airport and that the engine seemed like it was sputtering. The airplane subsequently impacted the upsloping terrain hard, and came to an abrupt stop less than one mile southwest of the departure runway. All major components of the airplane were located at the accident site. Postaccident examination of the airframe revealed no mechanical anomalies that would have precluded normal operation. Although the carburetor diaphragms exhibited tearing/cracks, the fracture surfaces were consistent with impact damage. No other mechanical anomalies were observed that would have precluded normal engine operation, and the reason for the reported loss of engine power could not be determined.
Probable cause
A loss of engine power for reasons that could not be determined.

- 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.
