During the landing, the airplane impacted terrain approximately 400 feet short of threshold for runway 22. The pilot reported, "I got too slow on approach and fell into a slower wind pocket which [decreased] my lift." The pilot attempted to add engine power, however, the airplane impacted terrain. The pilot estimated the wind was from 260 degrees at 20 to 40 knots and gusting. The pilot and passenger were not injured. Examination of the airplane revealed the main landing gear struts punctured the top of both wings. No mechanical anomalies were noted with the airplane.
