During rollout, the airplane began veering toward the right side of the runway. The student reported that he "stepped on the right rudder/brakes" and "lost directional control." An estimated 30-foot-long skid mark was observed on the runway leading off its right side. Thereafter, the airplane entered a grassy open field and came to rest upon colliding with the up sloping side of a ravine. ## Factual narrative The student pilot landed on runway 30, which is 4,500 feet long by 100 feet wide. During rollout, the airplane began veering toward the right side of the runway. The student reported that he "stepped on the right rudder/brakes" and "lost directional control." An estimated 30-foot-long skid mark was observed on the runway leading off its right side.
