Aircraft Accident/Incident Report
Tomah, Wisconsin 54660
Saturday, July 5, 2003 9:12 CDT
NTSB Narrative Summary Released at Completion of Accident
The airplane was destroyed and both occupants fatally injured during a forced landing attempt to a field. A witness reported that the airplane appeared to be having engine problems prior to the accident. Other witnesses described the airplane spinning to the ground. Control system continuity was verified during the postaccident examination. Examination of the engine revealed no fuel present in the carburetors, or intake manifold. There was a tear found in the fuel pressure regulator diaphragm. However, according to an engine manufacturer's representative, a tear in the fuel pressure regulator diaphragm would result in excess fuel being pumped by the fuel pumps directly into the intake manifold of the engine.
NTSB Probable Cause Narrative
The loss of engine power for an undetermined reason, and the pilot's failure to maintain airspeed resulting in a stall/spin during the forced landing.
