On May 30, 2005, about 1415 Pacific daylight time, a Cessna 172N, N172MR, veered off runway 29R, and came to rest inverted at Stockton Metropolitan Airport (SCK), Stockton, California. The pilot was operating the airplane under the provisions of 14 CFR Part 91. The student pilot, the sole occupant, was not injured; the airplane sustained substantial damage. The cross-country personal flight departed Lincoln Regional Airport/Karl Harder Field (LHM), Lincoln, California, about 1330, with a planned destination of Stockton. Visual meteorological conditions prevailed, and no flight plan had been filed. The pilot submitted a written statement. He reported that on the landing rollout, he applied the right brake too hard, and the airplane drifted to the right and off the runway. The airplane hit a low spot in the dirt and nosed over. The pilot stated that there were no mechanical discrepancies noted with the airplane and engine.
