He reported that, during his sixth landing, the airplane swerved to the left and subsequently swerved to the right during the landing roll. He attempted to control the airplane's direction with rudder pedal application, but he inadvertently applied the toe brakes, and the airplane nosed over. The airplane sustained substantial damage to both left side wing struts, the rudder, and the windscreen. The student reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The student pilot in the tailwheel-equipped airplane reported that he accomplished several takeoffs and landings to the asphalt runway during his solo flight in the pattern.
