## Discrepancy

DURING DOWNWIND FOR LANDING WITH A SIMULATED POWER LOSS, AN ACTUAL PARTIAL POWER LOSS OCCURRED. PILOT CONTINUED APPROACH AND LANDED WITHOUT FURTHER INCIDENT. DURING THE LANDING ROLLOUT, THE ENGINE QUIT. MAINTENANCE PERSONNEL RESPONDED AND TOWED THE AIRCRAFT FROM THE AIRCRAFT MOVEMENT AREA OF THE AIRFIELD. DURING THE INITIAL EXAMINATION OF THE AIRCRAFT IT WAS DETERMINED THAT FUEL FLOWED FREELY FROM THE CARBURETOR AIRBOX WHEN THE MIXTURE WAS PLACED IN THE FULL RICH POSITION. THE CARBURETOR WAS DETERMINED TO BE FAULTY AND WAS REPLACED. IT IS SUSPECTED THAT AN UNDETERMINED DEFECT IN THE CARBURETOR FLOAT OR ASSOCIATED VALVE ALLOWED THE CARBURETOR BOWL TO OVERFILL AND RESULTED IN FUEL OVERFLOWING INTO THE CARBURETOR VENTURI.
