N4348C

While departing runway 16 for a local flight, the private pilot in the front seat was piloting the airplane, while the commercial pilot followed along on the controls from the rear seat. When the airplane became airborne, it yawed to the right and crossed the left edge of the runway. Aircraft control was lost as the airplane's right wing suddenly dropped and the right main landing gear contacted the ground. The airplane descended and spun 180 degrees. Substantial damage was sustained to the fuselage. The pilot reported no mechanical malfunctions or failure prior to the accident. Winds at the time of the accident were reported calm, however an ultralight pilot, who had flown shortly before the accident airplane, reported a 5-10 knot wind from the south just above the runway.
