The pilot, with his three passengers, was climbing through 9,500 feet to fly over a mountain. He said that he encountered a severe downdraft and was unable to clear the mountain peak. He made a forced landing straight ahead, "for fear of a stall or spin into the trees." The airplane slid approximately 100 feet, separating the fixed landing gear and crushing inward the fuselage bottom. The density altitude at the accident location, an altitude of 8,795 feet, was calculated to be 11,955 feet. The density altitude at 9,500 feet was calculated to be 12,825 feet. The airplane manufacturer's representative said that "published engine performance charts indicate that the airplane had exceeded its certificated limitations." A postaccident engine test run was performed, and no anomalies were identified.
Probable Cause: The pilot's inadequate preflight planning (attempting to exceed aircraft's published certificated performance), the pilot not obtaining sufficient altitude to clear the terrain (not possible), and the pilot's inadequate in flight planning/decision making. Contributing factors were the high-density weather conditions, the downdraft weather conditions, and the mountainous terrain condition.
