Probable cause

A partial loss of engine power during the initial climb due to an in-flight fire of undetermined origin.

NTSB narrative

Following departure, the pilot banked the airplane to align with the right crosswind of the traffic pattern. He observed smoke entering the cockpit, and the engine began to produce only partial power. The pilot chose to return to the airport, but, due to the power loss, the airplane was unable to reach the runway. The pilot landed the airplane in a field outside the airport's perimeter. The exhaust clamp was found fractured. An area of the fracture appeared flat with granular features, but no clear evidence of preexisting cracks or progressive crack growth was observed. Circumferential cracks were noted in the retainer segments. Although these cracks may have been preexisting, they were not long enough to allow separation of the joint before the band fracture. The exhaust clamp likely fractured due to overstress loading of the joint during the landing. The cause of the in-flight fire could not be determined from the remaining evidence.
