NTSB narrative
THE PILOT/BUILDER COMPLETED A HIGH SPEED TAXI TEST ON THE RUNWAY BEFORE DEPARTING ON THE EXPERIMENTAL AIRPLANE'S FIRST FLIGHT. DURING THE TAKEOFF THE AIRPLANE FAILED TO CLIMB AFTER IT TRANSITIONED FROM GROUND EFFECT. THE ENGINE RPM WAS ADEQUATE, BUT THE AIRPLANE WOULD NOT CLIMB. THE REMAINING RUNWAY WAS INADEQUATE FOR A LANDING AND THE PILOT ATTEMPTED TO GAIN ALTITUDE BY INCREASING THE FLYING SPEED, BUT TO NO AVAIL. THE ALTITUDE WAS INSUFFICIENT AND THE AIRPLANE COLLIDED WITH THE TREES AT THE END OF THE RUNWAY. THE PILOT/BUILDER REPORTED THAT THE PROPELLER THRUST EFFICIENCY WAS INADEQUATE TO PRODUCE THE REQUIRED THRUST FOR CLIMB.
Probable cause
THE PILOT/BUILDER INADEQUATE PROPELLER COMPONENT RESULTING IN AN INADEQUATE CLIMB PERFORMANCE. CONTRIBUTING TO THIS ACCIDENT WAS THE AIRPLANE'S INABILITY TO CLIMB.

Source notes (4)
- 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.
