Analysis

The pilot reported that during approach to his private landing strip, the airplane ballooned. He stated that when the airplane came back down it was angled about 20 degrees from the runway centerline. He said that at this point there was less than 100 feet to the edge of the runway and the right wheel contacted snow about 10 to 12 inches deep. He stated that the deep snow "pulled [him] in" and that the airplane then nosed over. The damage to the airplane consisted of a bent rudder and a bent vertical stabilizer.
