Analysis

The acft was on a flt from sacramento, CA to vancouver, british columbia, via red bluff, klammath falls, eugene, portland & seattle. During a wx briefing at 0545 PST, the non-instrument rated plt was advised that VFR flt was not recommended. However, he filed a VFR flt plan & proceeded on the trip. When he filed a flt plan from klammath falls to eugene, he indicated that he would be cruising at 11,500 ft. subsequently, the acft crashed into wooded terrain at an elevation of about 5650 ft. the acft came to rest in a nose down attitude & partially buried in snow. An exam of the acft revealed no preimpact part failure or malfunction. There was evidence that the eng was providing power during impact. Personnel located about 4 mi north of the accident site reported the visibility was extremely low with fog.
