Investigator assessment
Analysis narrative
While on a cross country flight at 11,500 feet over mountainous terrain the engine began running rough. The pilot reversed course and set up for a forced landing in a clearing in a small valley. During the final portion of the approach, the engine smoothed out; however, the valley was too small for an exit to be accomplished. The pilot attempted to land on a road, but a wing tip caught and the airplane impacted into trees. No mechanical or system failure/malfunction was found during aircraft examination.
