The student pilot stated that he did not realize how close to the end of the runway he was and the airplane was traveling too fast to turn onto the intended taxiway exit. Subsequently, the airplane overran the departure end of the runway onto the dirt, which resulted in structural damage to the fuselage. The student pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The student pilot reported that following an uneventful practice no flap landing, he decided to exit the 3,799-foot long runway at the last taxiway exit and focused on maintaining runway centerline.
