NTSB narrative
Approximately 1 minute after takeoff, the pilot reported to the control tower that he had a problem and needed to circle back around. The aircraft impacted the ground next to the departure runway about 35 seconds after this call. The pilot reported that at about 200 feet, the engine started to make a 'missing' sound, the fuel flow indicated zero and then became erratic, and the aircraft began a violent vibration. At the accident site, FAA inspectors found fuel in one of the aircraft's tanks, with the other tank breached open and a strong odor of fuel. In post-accident examinations of the aircraft's engine and propeller, the only anomalies reported were low compression on one cylinder and slight wear on one cam lobe. No discrepancies were noted in the aircraft's recent inspection and maintenance history.
Probable cause
A loss of engine power for undetermined reasons. A factor was insufficient altitude available to return to the departure runway following the loss of power.

- 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.
