NTSB narrative
The pilot performed a preflight inspection, which included visually checking the fuel and oil levels. After starting the engine, all related instruments were in the normal operating range. The pilot then set up for a high-altitude takeoff, which included leaning the fuel mixture. He reported that the rotation was normal; however, at 400 feet above ground level (agl), the engine began to backfire and run rough. He enriched the mixture and engaged the auxiliary fuel pump with no change in engine operation. The stall warning horn sounded, so he lowered the nose and leveled the wings. The pilot stated that he thought he was at 300 feet agl when he began to look for a suitable landing area. He left the landing gear in the retracted position and held the airplane in a nose-high attitude until it impacted the ground. The airplane slid about 40 yards before it pivoted to the right and came to a stop. During the postaccident inspection, the engine was started and ran with no abnormalities noted. Additional testing of the fuel and ignition system components were accomplished. All components functioned on the manufacturer's test stands within specifications with no abnormalities detected.
Probable cause
A loss of engine power during initial climb 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: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2009-07-18.
