At about 19:00 EST, a Beech 76 crashed during an aborted landing attempt at Rowan County Airport. The instructor and multi-engine student were not injured. The pilots had nearly completed a training flight and had made an ILS approach and a touch and go. They remained in the pattern and planned to make a full-stop landing. During the approach, the instructor simulated a failure of the right engine. The student began to drift and the instructor said he could use both engines for landing. The student continued to drive and the instructor ordered a go-around. The student applied full power to only the left engine and the aircraft rolled to the right. The CFI took control and cut power to the left engine about the time the right wingtip dragged the ground.
