ACR CREW DEPARTS FROM DEN OVERWT.

Narrative

THE ACFT WAS A LATE INBOUND; SO WE DID A QUICK TURN. THE FO FILLED OUT THE LOAD MANIFEST AND HANDED IT TO ME (CAPT) TO LOOK OVER AND SIGN OFF. DURING THIS TIME THERE WERE A LOT OF DISTRS GOING ON WITH TRYING TO GET SET UP; WALKAROUND; CHKLISTS; JUMP SEATERS; AND MISSING INFO TO FILL OUT THE LOAD MANIFEST. BOTH THE FO AND CAPT OVERLOOKED THAT THE TKOF WT WAS OVER AND NOT UNDER THE MAX TKOF WT REQUIREMENT. WE DID THE SAME FOR THE LNDG WT -- SOMETHING THAT SHOULD HAVE BEEN CAUGHT; BUT WITH ALL THE DISTRS WAS OVERLOOKED. TAXIED OUT AND TOOK OFF WITH NO PROBS. DURING FLT; I WAS CHKING THE COMPUTER (FMS) AND NOTICED THAT WE WOULD BE OVERWT FOR LNDG. RECHKED THE PAPERWORK AND FOUND OUR ERROR. SLOWED THE ACFT DOWN AND HELD UNTIL THE COMPUTER SHOWED WE WERE UNDER MAX STRUCTURAL LNDG WT BEFORE WE STARTED THE APCH INTO RAP. MADE THE SOFTEST LNDG POSSIBLE AND TAXIED TO THE GATE. BOTH FO AND CAPT DID A POSTFLT WALKAROUND TO MAKE SURE THERE WAS NO STRUCTURAL DAMAGE AND AT THE REQUEST OF MAINT CTL; A MECH DID THE SAME AND SIGNED THE ACFT LOGBOOK OFF AS BEING CHKED AND IN GOOD CONDITION. PART OF OUR COMPANY'S FLEET HAS LOAD PLANNERS FOR THIS REASON. UNFORTUNATELY; OUR ACFT DOES NOT HAVE LOAD PLANNERS. I THINK THAT WOULD HELP GREATLY REDUCE INCIDENTS LIKE THESE FROM HAPPENING.
