NTSB narrative
When the pilot of the new, kit-built airplane realized he had lost throttle control, he decided to land at the home field of the manufacturer. He shut down the engine in the landing pattern, but miscalculated the power off descent rate, and landed short of his intended landing runway. Subsequent examination of the engine by factory personnel revealed that a castellated nut securing the cockpit throttle cable linkage to a threaded connection on the fuel metering shaft of the fuel servo had backed off due to a missing cotter pin. This allowed the linkage to disconnect and resultant loss of cockpit engine power control.
Probable cause
A loss of power control due to a disconnected throttle linkage. Also causal was the inadequate maintenance by the owner/builder.

- 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.
