NTSB Narrative Summary Released at Completion of Accident

On April 4, 2013, about 0930 mountain standard time, a Cessna 172S, N2166K, was substantially damaged when it impacted airport terrain during an attempted takeoff from Deer Valley Airport (DVT), Phoenix, Arizona. The certificated flight instructor (CFI), the student pilot, and the passenger were uninjured. The instructional flight was operated under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed. According to information provided by the flight school, the CFI, the student pilot, and the airplane were associated with the flight training program at Westwind School of Aeronautics (WSA), which was based at DVT. Examination of the CFI's pilot logbook indicated that he had a total flight experience of about 303 hours, all of which was in single-engine airplanes. Examination of the student pilot's logbook indicated that he had a total flight experience of about 4 hours, all of which was in the accident airplane make and model. The logbook indicated that his first instructional flight was conducted 6 days before the accident flight. According to information provided by the CFI and the responding inspector from the Federal Aviation Administration (FAA) Flight Standards District Office, the purpose of the flight was to practice takeoffs and landings. The student pilot was in the left seat, and the CFI was in the right seat. During the takeoff roll on runway 7R, the airplane began to veer to the right, and the CFI verbally instructed the student to correct back to the left. The airplane then veered toward the left side of the runway, while continuing to accelerate. About the time that the airplane crossed the runway centerline from right to left, the CFI took physical control of the airplane, and as it approached the left runway edge, the CFI attempted to lift off. After liftoff, the airplane nose "dropped," the airplane banked to the right, and struck the runway. About the same time the CFI reduced power on the engine. Paint transfer marks and airplane damage were consistent with the airplane striking the right wing and/or tailplane on the runway. The airplane came to rest inverted, adjacent to the south (right) side of the runway, about 1,450 feet from where the takeoff roll began. All occupants evacuated the airplane, and there was no fire, or any indications of a fuel spill. FAA records indicated that the airplane was manufactured in 2005, and was registered to a corporation based in Phoenix. It was equipped with a Lycoming IO-360 series engine. The elevation of DVT was 1,478 feet above mean sea level (msl), and runway 7R dimensions were reported as 8,196 by 100 feet. The airport was equipped with an air traffic control tower, which was operational at the time of the accident. The DVT 0953 automated weather observation included wind from 230 degrees at 3 knots; visibility 10 miles; clear skies; temperature 24 degrees C; dew point 1 degree C; and an altimeter setting of 30.05 inches of mercury.
