The elevator was found in a nineteen degree up position and both the left horizontal stabilizer and elevator were bent upward at the tip. The down elevator clevis was observed jammed against a section of bulkhead preventing the pilot from utilizing nose down elevator prior to impact. The acft stalled and fell into a nose down left spin, which continued to impact.
