AN ACR LGT BLEW A BAGGAGE CART INTO A WDB.

Narrative

ON OUR INITIAL CONTACT WITH DTW GND; GND INSTRUCTED US TO HOLD SHORT O-10; PLAN ON SEQUENCE IN FRONT OF MLG ON YANKEE SHORT OF O-10. THOUGH I THOUGHT THE INSTRUCTION MEANT HOLD SHORT OF O-10; THEY MIGHT HAVE MEANT HOLD SHORT ON 0-10; OR AT O-10; AND CAPT CREPT PART WAY ONTO O-10 IN ANTICIPATION OF SEQUENCE IN FRONT OF THE MLG ON YANKEE. GND PROCEEDED TO INSTRUCT THE MLG TO HOLD FOR US; AND WE TAXIED ONTO YANKEE IN THE PROPER SEQUENCE. 1 HR INTO FLT WE RECEIVED ACARS MESSAGE FROM COMPANY THAT OUR JET BLAST PUSHED A BAGGAGE CART INTO A WDB; CAUSING DAMAGE. NEVER DURING TAXI DID WE USE EXCESSIVE PWR. HOWEVER; THERE WAS ABOUT A 20 KT WIND BLOWING OUT OF W. THE ADDITIONAL THRUST FROM OUR ENGS ALONG WITH THE WIND MIGHT HAVE BEEN ENOUGH TO MOVE A CART INTO A WDB PARKED AT THE END OF THE CONCOURSE. CAPT REASONABLY WANTED TO TAXI ONTO O-10 PRIOR TO RECEIVING CLRNC ONTO YANKEE SO SMTS COULD GET BY US WHILE WE WERE WAITING. ALSO; WE TAXIED OUT ON ONLY 2 ENGS BECAUSE OF LONG LINE-UP ON YANKEE WAITING FOR CLRNC ON RWY 21R.
