Analysis

Before takeoff, the plt told ramp psnl that he & his wife were planning to take some pictures of the beautiful fall colors. A witness near the crash site observed an acft (matching the description of N48926) flying at low altitude. Subsequently, the acft crashed in a box canyon area where steep terrain prevailed on both sides & ahead of the acft. Elevation of the crash site was about 8000 ft. density altitude was estimated to be 10,400 ft. an exam of the wreckage revealed the acft had crashed in a steep nose down attitude. No evidence of a preimpact mechanical problem was found, except one of the bottom spark plugs contained enough lead deposits to fill the gap btn the center post (electrode) & one side of the plug. Chordwise scrapes were found on the prop blades. Also, a 3 inch limb was found at the crash site which had been sliced.
