The NTSB's narrative final · quoted from the NTSB record
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.
