The airplane was substantially damaged at 1200 Central time during a gear-up landing following an electrical system failure. The airline transport-rated pilot and passenger were not injured. Visual conditions prevailed.
While approaching the destination, the airplane suffered a complete electrical failure. The pilot and passenger attempted to identify the cause of the electrical failure without success. Without electrical power, the landing gear required manual extension. The pilot reported the passenger followed the emergency extension checklist as he flew the airplane. The pilot heard the gear extend and reported it appeared down when looking in the left wing tip tank mirror.
The pilot then continued the approach and was given a light gun signal by the tower, clearing them to land. The landing gear collapsed when the airplane touched down. The airplane slid approximately 200 feet prior to coming to rest with damage to the firewall.
