Analysis

The pilot reported departing the airport in the light-sport weight-shift-control airplane, and flying southbound along the western slopes of the Teton Mountain Range. The airplane climbed to an altitude of about 8,000 feet mean sea level, and the pilot changed course, approaching a canyon area to the east. As he approached rising terrain the airplane's rate of climb began to reduce. He elected to continue flight towards a plateau, due to ridges which were now encroaching from his left and right. He attempted to increase the airplane's rate of climb, and the airspeed subsequently began to decrease. He reported that as the airplane approached stall speed, he encountered a gust of wind and the airplane stalled. He lowered the airplane's nose, and was able recover control about 20 feet above ground level. He attempted to land ahead on the plateau, however during the landing roll, the nose landing gear collapsed, and the airplane rolled onto the right wing. The pilot sustained serious injuries during the accident sequence, and the airplane sustained substantial damage to both wings. The accident site was located in a remote area at the 9,800-foot-level on the western slope of the mountain range. The pilot utilized a SPOT Global Positioning System (GPS) emergency locator to summon assistance from search and rescue personnel, who located him about 2 hours after the accident. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation.
