He noted snowmobile tracks and patches of grass through the snow. After touching down, the airplane rolled for about 250 feet before the tires sunk into the snow. The airplane nosed over and came to rest on its back. The airplane’s right wing struts, vertical stabilizer, rudder and both wing tips were bent.
