NTSB narrative
The pilot of a powered glider experienced a partial loss of engine power on takeoff and landed hard while attempting a go around. During the preflight inspection and engine run-up, the pilot saw nothing abnormal that would have suggested a problem with the engine. After the accident, the pilot removed the powered glider wreckage from the accident site before the FAA inspector could inspect it. Approximately 3 months later, the powered glider was examined by an independent airframe and powerplant mechanic, and no definitive evidence was found that would have caused the partial loss of engine power. The inspection did reveal damage to the cylinder walls, but it was not possible to correlate this with the partial loss of engine power due to the engine being previously disassembled and examined by the owner.
Probable cause
A partial loss of engine power for undetermined reasons. Contributing to the accident was the pilot's failure to maintain adequate airspeed during the forced landing.

- 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, coordinates. 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.
