The 1,508-hour pilot lost control of the twin-engine airplane while landing on runway 17. The airplane went off to the side of the runway and hit a runway light. He reported that he "hit a gust of wind" while landing. The airplane rolled for about 400 feet before coming to a stop. An examination of the aircraft revealed that the nose wheel had collapsed into the wheel well, and the forward main bulkhead was bent and pushed out.
