Trenton-Robbinsville Airport
Aircraft Accident/Incident Report

Robbinsville, New Jersey 08691
Saturday, October 2, 2004 14:30 EDT

NTSB Narrative Summary Released at Completion of Accident

During the takeoff roll, and at an indicated airspeed of about 70 to 75 knots, the pilot felt the nose of the airplane dip and then rise off the ground. The pilot pushed the control yoke forward to level the airplane; it contacted the runway, and then skidded to a stop. The landing gear collapsed. Examination of the airplane revealed that the stabilator trim rod forward attachment hardware and the aft attachment nut were not installed. Photographs of the stabilator trim tab attachment point showed that it was visible and not obscured by any cowlings or coverings. The loss of the forward attachment hardware would result in an abnormal response, or "lightening," of the stabilator control. About 60 flight hours and 11 months prior to the accident, a repair station had removed, repaired, and reinstalled the stabilator trim tab.

NTSB Probable Cause Narrative

The repair station's improper installation of the stabilator trim tab. A factor was the pilot's inadequate preflight inspection of the airplane.
