The pilot stated that he saw terrain ahead of his flight path but "was too close to reverse course." The pilot stated that he "aligned the aircraft with the slope of the terrain and heard the stall warning" prior to impacting terrain. The airplane came to rest inverted, sustaining substantial damage. ## Factual narrative On October 25, 2004, at approximately 1335 mountain daylight time, a Cessna 310I, N8175M, piloted by a commercial pilot, impacted Point of the Mountain approximately 3 nautical miles south of Draper, Utah. Marginal visual meteorological conditions prevailed at the time of the accident. The personal flight was being conducted under the provisions of Title 14 CFR Part 91 without a flight plan.

According to the accident report submitted by the pilot, he was navigating with a global positioning system (GPS) unit to U77. Approximately 22 miles from U77, he "encountered rising terrain and pitched the aircraft up." The pilot stated that he saw Point of the Mountain ahead of his flight course but "was too close to reverse course."
