After landing and proceeding on the centerline, the pilot began to make a right turn following the taxi marker onto a taxiway. When the aircraft was off the runway, a brief and unusual nose wobble was detected. The nose of the aircraft then dropped to the runway and the propellers struck the pavement, causing the aircraft to come to an immediate stop. After separating from the aircraft, the nose wheel was observed approximately 3 to 5 feet from where it came to rest. It was observed that the wheel was smoking from the heat at the center bearing axle shaft, and there was a considerable amount of debris scattered near the front and rear of the aircraft. There was also debris from the nose wheel bearing housing found as far as 500 feet behind the aircraft. The nose landing gear structural attach points were substantially damaged. An FAA inspector reported the nose wheel bearing had failed and separated from the nose fork. The inspector also reported that the bearing and roller retainer on one side of the axle had disintegrated and was missing, while the bearing on the opposite side was void of any lubrication.
Probable Cause: The collapse of the nose landing gear while taxiing due to the failure of the nose wheel bearing. A factor was the lack of lubrication.
