Analysis

A Luscombe 8A ground looped on landing roll. The pilot indicated that during the landing roll after his third landing he heard a 'pop' sound. The aircraft veered right, collapsing the left main landing gear and damaging the left wing. After the accident the student pilot, who is also an airframe and powerplant mechanic discovered the left rudder cable was broken. The cable was examined in a metallurgical laboratory. The examination revealed that 42 of the 49 wires in the cable had fatigue characteristics at the wire breaks and the remaining 7 were entirely overstress fractures. The wire breaks had occurred within 0.5 inches of each other near a pulley.
