TKOF OF B737-400 CONSUMES MORE RWY THAN EXPECTED. FLT CREW LATER LEARNS THE ACFT WAS OVER MAXIMUM STRUCTURAL WT AND THE CENTER GRAVITY WAS OUT OF LIMITS FORWARD DUE TO EXCESS WT OF BAGS IN FWD CARGO PIT.

Narrative

ON TAKEOFF FULL LENGTH 34R OUT OF SEA USING IMPROVED CLIMB PERFORMANCE DATA THE AIRCRAFT DID NOT LIFT OFF UNTIL 1500 FEET BEFORE THE END OF THE RUNWAY. I LATER FOUND OUT THREE DAYS AFTER THE FLIGHT THAT THE LOAD WAS WRONG AND WE HAD MORE BAGS ON BOARD THAN WAS GIVEN THE OPS AGENT AND THEY WERE IN THE FWD PIT CAUSING THE FLIGHT TO BE OUT OF CG LIMITS FORWARD AND OVER ITS STRUCTURAL LIMITS. WE HAD WAITED UNTIL WE HAD RECEIVED THE NUMBERS BEFORE WE PUSHED TO PREVENT THIS FROM HAPPENING AND YET WE WERE STILL SENT OUT OVERWEIGHT AND OUT OF CG. I AM AT A LOSS AS TO HOW TO CURE THIS RECURRING PROBLEM. AFTER MAKING SEVERAL SUGGESTIONS OVER THE LAST FEW YEARS AND SEEING ABSOLUTELY LITTLE OR NO CHANGE I HAVE COME TO THE BELIEF THAT OBVIOUSLY MY SUGGESTIONS MAKE LITTLE OR NO DIFFERENCE. BUT I WILL SAY THAT IF THE INDUSTRY GOT AWAY FROM PERFORMANCE BONUSES FOR ITS COMPANY OFFICERS THEN THEY WOULD MAKE DECISIONS BASED ON LONG TERM THINKING INSTEAD OF SHORT TERM THINKING. THE RESULT WOULD BE QUALITY WORKERS THAT WOULD BE MORE MOTIVATED TO DO THE JOB CORRECTLY.
