Narrative:

We departed the ramp with our takeoff data indicating we would be close to maximum ramp weight and/or maximum takeoff weight. However, we didn't have our final passenger count or our final zero fuel weight. After a delay we received our final load close out. The zero fuel weight had been revised upward due to increased passenger load. When we added our ramp departure fuel weight to the actual zero fuel weight we discovered that we had taxied at a weight of 150700 pounds which was 200 pounds over the maximum ramp taxi weight. We notified maintenance and returned to the gate where the necessary inspections were completed. We then redeparted. One way to avoid this problem would be to remain at the gate until final numbers are received. This is probably operationally unacceptable. The only other way is for someone (load agent or crew) to monitor the situation very closely and not allow the aircraft to move until they can be assured the maximum weights aren't exceeded.

Title: ACR MLG RETURNS TO RAMP AFTER ACAR INFO REVEALS TAHT ACFT IS 200 POUNDS OVER MAX TAXI WT.

Narrative: WE DEPARTED THE RAMP WITH OUR TKOF DATA INDICATING WE WOULD BE CLOSE TO MAX RAMP WT AND/OR MAX TKOF WT. HOWEVER, WE DIDN'T HAVE OUR FINAL PAX COUNT OR OUR FINAL ZERO FUEL WT. AFTER A DELAY WE RECEIVED OUR FINAL LOAD CLOSE OUT. THE ZERO FUEL WT HAD BEEN REVISED UPWARD DUE TO INCREASED PAX LOAD. WHEN WE ADDED OUR RAMP DEP FUEL WT TO THE ACTUAL ZERO FUEL WT WE DISCOVERED THAT WE HAD TAXIED AT A WT OF 150700 POUNDS WHICH WAS 200 POUNDS OVER THE MAX RAMP TAXI WT. WE NOTIFIED MAINT AND RETURNED TO THE GATE WHERE THE NECESSARY INSPECTIONS WERE COMPLETED. WE THEN REDEPARTED. ONE WAY TO AVOID THIS PROBLEM WOULD BE TO REMAIN AT THE GATE UNTIL FINAL NUMBERS ARE RECEIVED. THIS IS PROBABLY OPERATIONALLY UNACCEPTABLE. THE ONLY OTHER WAY IS FOR SOMEONE (LOAD AGENT OR CREW) TO MONITOR THE SITUATION VERY CLOSELY AND NOT ALLOW THE ACFT TO MOVE UNTIL THEY CAN BE ASSURED THE MAX WTS AREN'T EXCEEDED.
