What happened
The non-instrument-rated private pilot departed in the early morning hours, before daylight, on a cross-country flight. There was no record of the pilot receiving a preflight weather briefing from either a Flight Service Station or a computer service. About 30 minutes into the flight, the airplane changed its heading twice with accompanying rapid changes in altitude. Shortly thereafter the airplane began a rapid descent and collided with steep mountainous terrain. According to radar analysis of the flight conducted by a Safety Board meteorology specialist, the first-half of the flight took place under visual meteorological conditions; however, during the remainder of the flight the airplane most likely entered both a wave cloud and a layer of broken-overcast clouds that bordered the flight path. Strong northwesterly winds normal to mountain ridges existed in the general area at the time of the accident. These winds would have caused the airplane to experience moderate to severe turbulence, and strong downdrafts due to either mechanical turbulence or mountain waves in the location where the final rapid descent occurred. There was no evidence of premishap mechanical malfunction or failure observed during the examination of the engine or airframe.
