NTSB narrative
The pilot reported that he intended to fly the airplane in the airport traffic pattern and perform several full-stop landings. During the engine run-up before the first takeoff, the engine ran roughly on the right magneto. The pilot leaned the fuel mixture, which resolved the problem. He then completed the pretakeoff checklist, and, subsequently, he took off in the airplane, completed the pattern, and made a full-stop landing. During the second takeoff, the pilot climbed the airplane to about 800 feet above ground level where the engine lost power. After turning the airplane back toward the airport, the pilot determined that the airplane would not reach the runway, so he maneuvered the airplane toward an open grassy area on the airport. During the landing, he side-loaded the left main landing gear, which subsequently collapsed. A postaccident test run of the airplane's engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The reason for the loss of engine power could not be determined.
Probable cause
The loss of engine power during initial climb for reasons that could not be determined because a postaccident examination of the engine did not reveal any anomalies that would have precluded normal operation.

- 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.
