NTSB narrative
The pilot reported that the run-up and takeoff were normal. The airplane was at about 2,500 ft mean sea level when the pilot heard a reduction in engine power before it abruptly lost power. The pilot initiated a forced landing onto an abandoned runway; it exited the end of the runway and impacted vegetation before coming to rest. The airplane sustained substantial damage to the wings. Postaccident airframe and engine examination revealed no anomalies that would have precluded normal operation. The reason for the loss of engine power could not be determined based on the available evidence.
Probable cause
A total loss of engine power 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: 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.
