NTSB narrative
The pilot was taxiing the weight-shift control aircraft to the runway to depart when his wife heard a loud “bang” from inside the house. There were no witnesses to the accident. The aircraft was found upright against a fence along a grass taxiway. The aircraft sustained substantial damage to the fuselage.
The pilot’s son reported that his father recently replaced the throttle cable on the aircraft. After the throttle cable change, the pilot reported the throttle cable was “sticking.” The engine was examined, and the throttle cable was found installed correctly at the engine and at the cockpit. The throttle cable at the cockpit throttle control position did not have a full range of motion and was found jammed with little to no movement available; however, whether this occurred before the accident or was the result of impact damage could not be determined.
Available medical information provided no evidence that a medical factor contributed to the accident.
The circumstances of the accident are consistent with a loss of control while the pilot was taxiing the aircraft; however, the reason for the loss of control could not be determined based on the available evidence.
Probable cause
A loss of control while taxiing for reasons that could not be determined based on available evidence.

- 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, cause areas. 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.
