Analysis

The pilot was on a VFR cross country flight when the aircraft descended rapidly and collided with trees. Several witnesses reported hearing extensive engine surges. Witnesses reported seeing the acft maneuvering in a highly erratic manner, then begin a nose dive followed by acft rotation. All the witnesses stated that they heard the acft's engine surge to a high setting just prior to impact. The acft was heading west when it impacted in a 40 degree nose down attitude and a 45 degree right bank. The acft debris were scattered throughout a 100 by 200 foot area of the densely forrested, hard ground. The area forecast included mountain obscurations, moderate rime or mixed icing, and turbulence with visibilities between 3 to 5 miles. The local weather was as forecast according to local witnesses and by airline employees.
