## Discrepancy

(( MZ2R)) AFTER NORMAL RUN-UP, THE ACFT PROCEEDED TO TAKEOFF, ON ROLLOUT SMOKE WAS NOTED.  THE PILOT WAS COMMITTED TO TAKEOFF, THE ENGINE WAS STILL GENERATING POWER AT THAT TIME, THE ENGINE/PROPELLER WERE SHUTDOWN/ FEATHERED.  A NORMAL LANDING OCCURRED.  AFTER UNCOWLING THE LT ENGINE, A HOLE WAS NOTED ABOVE NR 4 CYLINDER IN THE ENGINE CASE.  NR 4 PISTON CONNECTING ROD WAS NOTED BROKEN IN HALF.  THE ENGINE HAS NOT BEEN REMOVED FROM THE ACFT AS OF YET FOR FURTHER INVESTIGATION.
