NTSB narrative
The pilot reported that he had not held any kind of pilot certificate since his student pilot certificate expired about 40 years ago. He also reported that he had no record of receiving any flight instruction. During takeoff, after liftoff from the departure end of the runway, the airspeed was too slow and the airplane would not climb and would not accelerate. The airplane drifted to the left and impacted trees and terrain on the edge of the airfield property. After the pilot and passenger exited the airplane there was an explosion and the airplane was destroyed by the postimpact fire. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The noncertificated pilot's operation of the airplane, which resulted in impact with terrain.

Source notes (4)
- 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.
