The student landed the airplane off the runway centerline and then raised the flaps and added power. The airplane continued forward and impacted snow along the edge of the runway, nosed over, and then came to rest inverted. The airplane sustained substantial damage to the right wing and vertical stabilizer. The instructor and student reported that there were no preaccident mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. ## Factual narrative The student pilot and flight instructor reported that after conducting maneuvers they proceeded to the airport to practice touch-and-go takeoff and landings.
