On October 28, 2004, at approximately 0820 mountain daylight time, a Cessna 152, N5290B, piloted by a student pilot, was substantially damaged when it impacted terrain and subsequently nosed over during takeoff roll from Dona Ana County Airport (5T6), Santa Teresa, New Mexico. Visual meteorological conditions prevailed at the time of the accident. The training flight was being conducted under the provisions of Title 14 CFR Part 91 without a flight plan. The pilot reported no injuries. The local flight originated at approximately 0745. According to the accident report submitted by the student pilot, he had performed two touch and go landings on runway 28. During the ground roll, the pilot advanced the throttle forward to perform another takeoff. The pilot reported that the airplane "veered sharply to the left" and departed the runway. He stated that he was not able to "reduce the power" because it was bumpy. The nose wheel struck an outcropping of sagebrush, separating the nose gear. Subsequently, the airplane nosed over. The top 12 inches of the vertical stabilizer and rudder were crushed to the left and the leading edge of the right wing tip was crushed down and aft. The engine cowling was wrinkled and crushed and the propeller separated at the hub. A postaccident inspection of the airplane systems, by the FAA inspector, revealed no anomalies.
