Analysis

In cruise flt the PIC smelled something burning and noticed black and white smoke pouring fm the eng cowling. This was followed by a partial loss of pwr. A precautionary landing was made in a field. The PIC noticed flames erupting fm the eng area after exiting the acft. Later inspection revealed a loose exhaust collector ring clamp had slipped out of position. The resultant separation of the exhaust tubing allowed the hot exhaust to be diverted to the carburetor area of the eng and a fire ensued. The hot exhaust was ingested into the carburetor inlet contributing to the eng's partial pwr loss.
