Investigator assessment
Analysis narrative
The pilot reported that shortly after takeoff, he noticed flames coming from under the engine cowling. He maneuvered the airplane into the downwind pattern for the runway as the fire continued to develop in the airplane. Unable to make the runway, the pilot landed the airplane off field. The airplane was destroyed by the fire. After the airplane was recovered, extensive fire damage was observed with the engine. The mechanical fuel pump was completely consumed during the fire. Due to fire damage the fuel pump could not be tested or examined and the reason for the inflight fire was not determined.
