On August 8, 1996, at 1500 central daylight time (cdt), a Cessna 150, N3510L, piloted by a student pilot, was substantially damaged when it nosed over following a loss of directional control during landing roll at Plattsmouth Airport, Plattsmouth, Nebraska. The student pilot reported no injuries. The personal 14 CFR Part 91 flight was operating in visual meteorological conditions. No flight plan was on file. The flight departed Plattsmouth, Nebraska, at 1430 cdt. According to the student pilot's written statement, after landing on runway 16 at Plattsmouth Municipal, when the nose gear contacted the runway surface, the airplane veered sharply to the left. The airplane drifted off the runway and nosed over. A Federal Aviation Administration Principal Maintenance Inspector (PMI) represented the NTSB on-scene. The PMI said the nose gear assembly was checked for proper centering and security. The nose gear lower strut assembly was removed and inspected. The nose steering system and rudder control system were examined and checked for continuity. Subsequent investigation failed to disclose any mechanical malfunction.
