Aircraft Accident/Incident Report

Ann Arbor, Michigan 48108
Friday, April 8, 2005 9:20 EDT

NTSB Narrative Summary Released at Completion of Accident

The airplane was damaged during a forced landing following a loss of engine power during a go-around. Engine runs subsequent to the accident revealed that the engine would run rough when advanced to 1,400 rpm. The engine operated throughout it's operational rpm range when fitted with a carburetor from another airplane. The accident carburetor was found to be missing the accelerator pump nozzle tube. No other discrepancies were noted.

NTSB Probable Cause Narrative

The failure of the carburetor nozzle resulting in loss of engine power and the unsuitable terrain encountered during the forced landing. A factor was the low altitude.
