The aircraft encountered elevator control problems while en route and landed safely at his destination. During a post-landing inspection, ice formation was found in the tail section of the aircraft in an area surrounding the elevator control cables. The water drain hole and limbers that evacuate this area were found clogged with fuzz-like fibers.
Probable Cause: Water accumulation in the tail section of the aircraft that froze around the elevator control cables which restricted the movement of the elevator. Contributing factors were the accumulation of debris in the limbers and drain hole for the affected area. A finding was the fact that this area cannot be easily inspected by the pilot due to the need for hand tools to gain visual access.
