At 1120 eastern time, a Piper PA-32RT-300T was damaged when its nose wheel collapsed during landing at Fayetteville, N.C. The pilot was not injured. The pilot reported that the elevator flight control became unresponsive in flight. Using only elevator trim to control pitch, the pilot flew to Fayetteville Regional Airport, where he requested the longest runway for an emergency landing. The nose of the airplane dropped when the pilot reduced power to land, causing the nose wheel to collapse on impact with the runway. A post-flight inspection revealed that the left elevator cable assembly turnbuckle was broken.
