On June 22, 2002, about 0930 eastern daylight time, a Cessna 172N, N739PF, registered to and operated by Atlanta Northside Aviation Inc., nosed over during landing, at the Cobb County/McCollum Field Airport, Marietta, Georgia. Visual meteorological conditions prevailed at the time and no flight plan was filed for the 14 CFR Part 91 training flight. The airplane was substantially damaged. The student pilot reported no injuries. The flight had originated from the same airport, at 0920. The student pilot said he was on a solo flight practicing touch-and-go landings. After landing on runway 9, he initiated the takeoff sequence by retracting the flaps, and shutting off the carburetor heat. He then added "full power" to the airplane's engine. The airplane's nose "veered left," he applied right rudder to correct, but the airplane "kept moving left." The student pilot said he applied brakes in an attempt to control the airplane, and "pulled the throttle back," before the airplane departed the "left" side of the runway. After the airplane departed the runway it entered the grassy area along side of the runway, struck a gully, and nosed over. No mechanical discrepancies were reported or found with the airframe or engine.
