On October 2, 2003 at 1530 eastern daylight time, a North American T6G, N2831D, registered to Bowlin & Associates Inc, and operated by the commercial pilot, ran off the side of runway 23 and into an embankment at the Heavens Landing private airstrip in Clayton, Georgia. The personal flight was operated under the provisions of Title 14 CFR Part 91, and visual flight rules. Visual meteorological conditions prevailed and no flight plan was filed. The pilot received minor injuries, and the passenger was not injured. The airplane sustained minor damage. The flight originated from a private airstrip in Griffin, Georgia, at 1430. According to the pilot, he elected to land on runway 23 with a slight tail wind. He said the winds were light and variable with occasional gusts. The runway was a newly constructed concrete surface, which measured 5,000 feet by 50 feet. The south side of the runway drops off approximately 20 feet from the runway edge into a 15-foot deep embankment. The pilot stated that the airplane touched down about 500 feet down runway 23 on the centerline. As the tail lost lift and the tail wheel made contact with the runway, the airplane veered left off the centerline. At 1900 feet, the airplane crossed from the south side of the runway over the centerline to the north side of the runway. The airplane veered again to the left and departed the runway on the south side about 2,000 feet from the approach end. The airplane came to rest perpendicular to the runway 2,144 feet from the approach end. Winds at the time of the accident were100-degrees gusting to 15 knots. Examination of the accident on-scene found that the airplane collided was an embankment and several large rocks. The examination also revealed that both main landing gear were separated from the airframe. Examination of the auto-locking feature for the tail-wheel found that the mechanism operated properly. Tail wheel skid marks on the runway were clearly visible throughout the length of the loss-of-control sequence. Tail wheel scuff marks were in line with the main landing gear and exhibited side-load scuffing consistent with the tail wheel being in the locked position. The scuffing was not consistent with a cocked tail wheel. In addition, no evidence was identified indicating tail wheel tire sidewall or tread damage consistent with a cocked tail wheel. No mechanical problem with the airplane was reported by the pilot. **This narrative was modified on August 9, 2007.**
