The pilot reported that he had performed a stop-and-go in a dirt clearing with a slight upslope. The pilot attempted to land in the clearing a second time, but during the landing flare, the pilot realized that he was going to land about 50 to 100 ft past his previous landing point and observed large sticks and a dirt mound in the available landing area ahead of the airplane. The pilot said that he initiated a go-around by applying full power and noted that he did not have the performance while in the low energy state. Subsequently, the landing gear briefly contacted the ground and the left wing dropped before the airplane impacted terrain. During the accident sequence, the left wing, left flaperon, and fuselage sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
