A DC10-10 ON APCH AT 4000 FT HAD THE WING LEADING EDGE SLATS FAIL TO EXTEND CAUSED BY A BROKEN R WING DRIVE CABLE.

Narrative

ON APCH TO MSP; SLATS WOULD NOT EXTEND. WE ACCOMPLISHED RED TABS AND PERFORMED AN UNEVENTFUL 22 DEG RETRACT LNDG. I DID NOT DECLARE AN EMER -- EVERYTHING WAS PROCEEDING AS PER OUR TRAINING AND THE WX WAS GOOD AND RWY LONG. HOWEVER; UPON RETROSPECT; I SHOULD HAVE; AND SHOULD HAVE ASKED FOR EMER VEHICLES STANDING BY; AS OUR TOUCHDOWN SPD WAS NOT A LOT LOWER THAN OUR MAX TIRE SPD (195 KTS); AND WHO KNOWS THE TRUE CONDITION OF THE TIRES? IN THE FUTURE; WE'LL CALL FOR TRUCKS STANDING BY SO WE WON'T TURN INTO AN EMER. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A DC10-10 AND WHEN LNDG FLAPS WERE SELECTED; THE SLAT DISAGREE LIGHT CAME ON IMMEDIATELY AND IT WAS THEN NOTED THE LEADING EDGE SLATS DID NOT EXTEND. THE RPTR SAID THE LEADING EDGE SLATS REMAINED IN THE RETRACT POS AND THE ACFT WAS LANDED WITHOUT SLAT EXTENSION. THE RPTR STATED THE CAUSE OF THE FAILURE WAS THE R WING DRIVE CABLE BROKEN AND ASSOCIATED CABLE PULLEYS AND PULLEY BRACKETS DAMAGED.
