NTSB narrative
According to the pilot, the airplane sustained a total loss of engine power during the approach to land. Unable to maintain altitude, the pilot initiated a forced landing to rough desert terrain. During the landing roll, the landing gear collapsed and separated, and the airplane slid about 100 ft before coming to rest upright.
Examination of the airframe and engine revealed no evidence of preimpact malfunctions or anomalies. Residual fuel was found in fuel lines and fuel components in the airframe and engine. The reason for the loss of engine power was undetermined.
Probable cause
The 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, cause areas. 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.
