Analysis

When the acft did not return from a x-country flt, a search was initiated. However, the acft was not found until hikers discovered the wreckage on 6/29/84. Impact occurred at about the 9000 ft level in mountainous terrain. The outer wing panels & horizontal stabilators were found at a remote distance from the main wreckage. An exam of the fracture surfaces revealed no preexisting cracks. Prior to the flt, the non-instrument rated plt was advised that VFR flt was not recommended. The mountain tops were forcasted to be obscured with broken to overcast cloud bases at 8000 to 10,000 ft. cloud tops were forcasted to be in the vicinity of 20,000 ft. snow showers were expected above the freezing level.
