Experimental Amateur-Built Airplane Stalls During Takeoff After Rudder Control Horn Installed Upside Down

Accident Sequence

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

Post-Accident Inspection

Following the accident, the pilot performed an inspection of the airplane with the assistance of another pilot. The inspection discovered that the rudder control horn had been installed upside down. This improper installation reversed the rudder control input. When right rudder input was needed during takeoff to overcome the airplane's left turning tendency caused by the engine and propeller, pressing the right rudder pedal made the airplane turn left. The pilot recommended that he verify proper control connections after maintenance.
