Narrative:

On second leg of first day was contacted on ACARS and told to call flight manager upon arrival at destination. After landing, called flight manager and he advised that on first leg of day as we were departing gate X at ord on flight ord-dfw, we blew a baggage cart into a parked airplane causing some damage to the parked aircraft. I advised the flight manager that we were pushed back from gate 'tailed to the north' (facing south). Upon calling ground control we were given a revised taxi route which required an initial taxi to the north. As gate X is a gate high potential for jet blast damage, I was very careful not to add power above the breakaway thrust indices on the N1 gauge, as we were heavy and it was warm outside accompanied by an uphill taxi. I had to leave the breakaway thrust at the indices longer than normal. I proceeded perpendicular to taxiway a and began a right turn north as I approached taxiway a. I feel that the heavy gross weight accompanied by the warm outside air temperature, uphill grade and the fact that I had to turn north on taxiway a instead of south all contributed to the need for the extended use of breakaway thrust. The only solution I can think of would be to tow all aircraft onto taxiway a before applying thrust.

Title: MLG JET BLAST BLOWS BAGGAGE CART INTO ANOTHER PARKED ACFT DURING TAXI FROM GATE AREA.

Narrative: ON SECOND LEG OF FIRST DAY WAS CONTACTED ON ACARS AND TOLD TO CALL FLT MGR UPON ARR AT DEST. AFTER LNDG, CALLED FLT MGR AND HE ADVISED THAT ON FIRST LEG OF DAY AS WE WERE DEPARTING GATE X AT ORD ON FLT ORD-DFW, WE BLEW A BAGGAGE CART INTO A PARKED AIRPLANE CAUSING SOME DAMAGE TO THE PARKED ACFT. I ADVISED THE FLT MGR THAT WE WERE PUSHED BACK FROM GATE 'TAILED TO THE N' (FACING S). UPON CALLING GND CTL WE WERE GIVEN A REVISED TAXI RTE WHICH REQUIRED AN INITIAL TAXI TO THE N. AS GATE X IS A GATE HIGH POTENTIAL FOR JET BLAST DAMAGE, I WAS VERY CAREFUL NOT TO ADD PWR ABOVE THE BREAKAWAY THRUST INDICES ON THE N1 GAUGE, AS WE WERE HVY AND IT WAS WARM OUTSIDE ACCOMPANIED BY AN UPHILL TAXI. I HAD TO LEAVE THE BREAKAWAY THRUST AT THE INDICES LONGER THAN NORMAL. I PROCEEDED PERPENDICULAR TO TXWY A AND BEGAN A R TURN N AS I APCHED TXWY A. I FEEL THAT THE HVY GROSS WT ACCOMPANIED BY THE WARM OUTSIDE AIR TEMP, UPHILL GRADE AND THE FACT THAT I HAD TO TURN N ON TXWY A INSTEAD OF S ALL CONTRIBUTED TO THE NEED FOR THE EXTENDED USE OF BREAKAWAY THRUST. THE ONLY SOLUTION I CAN THINK OF WOULD BE TO TOW ALL ACFT ONTO TXWY A BEFORE APPLYING THRUST.
