The trip itinerary began at 0530 hrs on the morning of the accident with several stops planned at various airports in Arizona and New Mexico, with a long stopover at Page. In the evening, the pilot got a weather briefing and filed a flight plan for the return leg from Page to Tucson. The pilot gave his route of flight as V293 at an altitude of 8,500 ft MSL. The aircraft struck trees on the North Rim of the Grand Canyon at an altitude of 8,540 ft MSL. The accident site is about 2 degrees from the center line of V293. A witness heard the aircraft approach the accident site and reported strong engine sounds until impact. The witness saw the aircraft strobe and navigation lights approach the accident site in level flight then disappear into the trees; an explosion and fireball were seen immediately thereafter. The night was clear and dark with no moon. The VFR sectional lists 9,200 ft MSL as the minimum sector altitude for the accident area.
