Analysis
While en route, the plt encountered a progressive, partial power loss. At 1st the eng began running rough, then the manifold pressure dropped to 15 inches (18 inches had been set for cruise). He heard a clicking noise & started a descent from his cruise alt of 8500 ft. he began a precautionary landing. When he saw that the wind would carry the acft beyond the field he had selected, he used what available power he had to cross over a road & a pond, and to avoid a transmission line. However, he was unable to avoid a fence. The plt stated that the acft tore thru a fence, just before touchdown. An investigation revealed that the #4 exhaust pushrod was bent & the housing was broken.
