NTSB narrative
A witness, who was a repair facility employee, stated that, on the morning of the accident, the airplane was fueled and then flown for about 15 to 20 minutes without incident. The accident flight was the second flight of the day and was also about 15 to 20 minutes long. The witness's cell phone video revealed that the airplane was on short final for the runway as it descended and turned left; it then disappeared into a wooded area. The airplane collided with a tree and then impacted the ground and came to rest upright. First responders to the accident site stated that the fuel lines had been severed, and fuel was covering the ground under the airplane.
The propeller blades did not exhibit signs of power during impact. Postaccident testing of the engine's distributors and fuel pump did not reveal any anomalies. However, postaccident testing of the injection carburetor revealed that the right float switch pin was dislodged from its cylinder, but it could not be determined when the pin became dislodged. The pin was reinstalled into its cylinder, and subsequent testing of the injection carburetor revealed that it was out of tolerance; however, the specialists at the repair station stated that, although several of the carburetor readings were out of tolerance, none of the indications would have caused a loss of engine power.
Postaccident examination of the engine did not reveal any evidence of preimpact mechanical malfunctions or anomalies that would have precluded normal operation. The fuel selector was found positioned to the auxiliary fuel tank line, not the main fuel tank line. The valve was impact-separated from the airplane, and its preaccident position could not be confirmed. Based on the available evidence, the reason for the loss of engine power could not be determined.
Probable cause
A total loss of engine power for reasons that could not be determined because postaccident engine examination and testing did not reveal any mechanical malfunctions or anomalies that would have precluded normal operation.

- 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.
