HE RPRTD THE ACFT WAS STILL AIRBORNE ABOUT HALFWAY DOWN THE RWY WHEN HE ELECTED TO GO AROUND. HE ATTEMPTED TO ADD POWER, BUT THE ENG 'SPUTTERED & DIED.'  THE PLT SAID HE FORCED THE MAIN GEAR ONTO THE RWY & APPLIED BRAKES, BUT WITHIN SECONDS, THE ACFT NOSED OVER. AFTER THE ACDNT, AN EXAM REVEALED THE LEFT MAIN WHEEL HAD BROKEN OFF AT THE AXLE, THEN THE LEFT STRUT DUG INTO THE GROUND & THE ACFT NOSED OVER. THE PLT RPRTD THAT WHEN THE ACFT WAS ON FINAL APCH, HE HAD MOVED THE CARBURETOR HEAT TO OFF. THE TEMP & DEW POINT WERE 43 & 26 DEG, RESPECTIVELY. ACCORDING TO ICING PROBABILITY CHARTS, CONDS WERE CONDUCIVE FOR CARB ICE. EXCEPT FOR SOOT IN THE EXHAUST STACKS & ON THE SPARK PLUGS, NO EVIDENCE OF A PRE-ACDNT MECHANICAL PROBLEM WAS FOUND.
