Narrative:

Due to a lengthy maintenance delay, we were 2 1/2 hours late leaving gate for departure. All of the passenger who were connecting through dfw were taken off the aircraft. The load dropped from approximately 110 passenger to 60 passenger. Taxiing out, I requested new takeoff numbers (tps) which we received over our ACARS. Also, our flight plan had timed out so we had to request a new IFR flight plan to dfw. We got the takeoff numbers and flight plan as we were approaching the runway. All takeoff speeds and power settings and weights were lower as per the new load of reduced people. Sometime after takeoff we got a load closeout over the ACARS which reflected the reduced load. In the rush to get the flight airborne, without further delay, we had not looked at the final closeout. But the new takeoff numbers did have the corrected weights on it. We had the proper takeoff bug speeds and power programmed into the aircraft, but we still should have checked for the load closeout before departing. Lesson learned. Even if you are late, take the extra time to make sure each step is covered.

Original NASA ASRS Text

Title: AN ACR CREW TOOK OFF WITH INCOMPLETE AND WRONG LOAD DATA.

Narrative: DUE TO A LENGTHY MAINT DELAY, WE WERE 2 1/2 HRS LATE LEAVING GATE FOR DEP. ALL OF THE PAX WHO WERE CONNECTING THROUGH DFW WERE TAKEN OFF THE ACFT. THE LOAD DROPPED FROM APPROX 110 PAX TO 60 PAX. TAXIING OUT, I REQUESTED NEW TKOF NUMBERS (TPS) WHICH WE RECEIVED OVER OUR ACARS. ALSO, OUR FLT PLAN HAD TIMED OUT SO WE HAD TO REQUEST A NEW IFR FLT PLAN TO DFW. WE GOT THE TKOF NUMBERS AND FLT PLAN AS WE WERE APCHING THE RWY. ALL TKOF SPDS AND PWR SETTINGS AND WTS WERE LOWER AS PER THE NEW LOAD OF REDUCED PEOPLE. SOMETIME AFTER TKOF WE GOT A LOAD CLOSEOUT OVER THE ACARS WHICH REFLECTED THE REDUCED LOAD. IN THE RUSH TO GET THE FLT AIRBORNE, WITHOUT FURTHER DELAY, WE HAD NOT LOOKED AT THE FINAL CLOSEOUT. BUT THE NEW TKOF NUMBERS DID HAVE THE CORRECTED WTS ON IT. WE HAD THE PROPER TKOF BUG SPDS AND PWR PROGRAMMED INTO THE ACFT, BUT WE STILL SHOULD HAVE CHKED FOR THE LOAD CLOSEOUT BEFORE DEPARTING. LESSON LEARNED. EVEN IF YOU ARE LATE, TAKE THE EXTRA TIME TO MAKE SURE EACH STEP IS COVERED.
