Incident Overview
A pilot reported that while flying near a relative's house, he switched fuel tanks and the engine began running rough. Suspecting that the magnetos, which had recently been serviced, were the cause, he switched fuel tanks again with the boost pumps turned on. The engine then ran smoothly.
Decision to Land
Despite the engine returning to normal operation, the pilot decided to make a precautionary landing in an open field to inspect the magnetos on the ground. During the landing approach, the main landing gear caught in a rut, causing the gear to collapse. As the pilot attempted to turn and stop the aircraft, it struck a fencepost.
Damage and Aftermath
The collapse of the main landing gear and the impact with the fencepost resulted in damage to the aircraft. The pilot's account does not specify the extent of injuries or additional details about the aircraft or location.
