The right main landing gear collapsed during rollout following a normal touchdown on the runway. Thereafter, directional control was lost, and the right wing struck the surface of the runway. The airplane veered off the runway, and it came to rest in an adjacent open dirt field. During flight the pilot had experienced a low voltage condition, and his radio communications became problematic as the battery gradually discharged. The pilot cycled the airplane's master electric system switch in accordance with instructions in the Cessna Pilot's Operator's Handbook. Because this did not restore electric power, the pilot reduced the electrical load to conserve energy. No evidence of any mechanical malfunction was found during the post impact examination of the landing gear and alternator/battery electric system. During the examination the alternator field circuit breaker was found in the tripped position. The examination revealed that when the alternator circuit breaker was reset, electric current was restored to the buss and the battery was charging. Prior to landing, the pilot failed to properly perform procedures relating to ensuring that the alternator circuit breaker was engaged. Also, the pilot failed to ensure that the landing gear was fully extended by using the emergency gear extension system.
Probable Cause: The pilot's failure to ensure that the landing gear was fully extended, by use of the emergency gear extension system, which resulted in its partial collapse during landing rollout. Also causal was the pilot's failure to follow POH procedures relating to troubleshooting and restoring electric power to the airplane busses.
