NTSB narrative
On the morning of the accident, the pilot terminated his first flight early due to a fuel leak in the fuel tank sight gauge. The pilot made a repair before taking off for a second flight. During the second flight, witnesses reported seeing the airplane in distress and hearing the engine sputtering as it approached an open field. The airplane overflew a set of power lines before rolling and impacting terrain, consistent with the pilot reducing the airspeed in an attempt to clear the power lines during a forced landing and subsequently stalling the airplane. The majority of the airplane fuselage and cockpit were consumed by a postimpact fire. Flight control continuity was verified from the cockpit to all flight control surfaces. Examination of the fuel system and engine were limited due to the fire damage, and a reason for the apparent loss of engine power could not be determined.
The pilot hadn't flown in 10 years and had recently purchased the airplane. The pilot logged one flight with an instructor about 2 months before the accident, and he had not logged experience in the airplane type before the day of the accident.
Probable cause
The pilot’s loss of control during a forced landing following a loss of engine power for reasons that could not be determined due to postimpact fire damage.

- 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.
