The pilot of the experimental amateur built airplane reported that during the takeoff roll the airplane veered to the left. As the airplane neared the left edge of the runway, the pilot rotated the airplane in an attempt to be come airborne, but the airplane aerodynamically stalled three feet above the runway and then impacted the runway nose first.

The pilot reported that he performed a post-accident inspection of the airplane with the assistance of another pilot, and he discovered that he installed the rudder control horn upside down. The improper installation reversed the rudder control input. When right rudder input was needed during takeoff to overcome the airplane's left turning tendency precipitated by the engine and propeller, pushing on the right rudder pedal made the airplane turn left. The pilot recommended that he verify proper control connections after maintenance.

According to the pilot/owner/builder of the airplane, he conducted taxi tests, and then a final engine run-up and flight control check prior to takeoff on the airplane's second flight. After rotation, the airplane reached approximately 3 feet above the runway when the nose dropped, and application of full up elevator had no effect. The airplane struck the runway nose first, which resulted in substantial damage to the firewall. This was the identical outcome as the first flight several months prior. An FAA inspector estimated that the builder had added about 63 pounds with his modifications to the original airplane plans. The pilot performed the weight and balance on the airplane using bathroom scales and stated that there were no mechanical deficiencies that would have precluded normal operation of the airplane. His NTSB Form 6120.1 Operator/Owner Safety Recommendation was: "Re-weigh aircraft with calibrated scales to determine weight and balance. Fix apparent nose heavy aircraft with appropriate movement of the battery or additional weight in the tail section."
