Investigator assessment
Analysis narrative
The pilot reported that while in cruise flight at an altitude of 1,300 feet, the engine started to lose power and "created a rattling sound". The pilot tried to return to his departure airfield but was unable; and elected to perform a forced landing on a dirt road. During the landing the aircraft's nose gear collapsed and the aircraft came to stop against a fence post. An inspection of the engine by the aircraft owner revealed that one of the connecting rods had failed.
