Narrative:

We pushed from the gate on time. We were in no way rushed -- neither was the operations agent from my point of view. We received the load sheet with an oew of 72347 pounds, nothing in total passenger weight, aft hold weight of 1098 pounds, operational weight of 73445 pounds, an adjustment of +201 pounds, and final ZFW of 73646 pounds. The fuel weight was 16802 pounds, and takeoff weight was 90448 pounds. I did not notice that nothing was entered in the passenger weight line. I calculated the takeoff data using the opc, and used speeds of V1-116, vr-116, V2-126, and trim of 4.8. We taxied to runway 19R, and took off without incident. Climbing through 10000 or 15000 ft, I called operations to report our takeoff and push times. The person at operations relayed to me that the operations agent had neglected to include the passenger weight on the load sheet. He gave me the corrections. Though it was a moot point, I recalculated the takeoff data, and found the correct speeds were V1-123, vr-123, V2-132. The captain (PF) said he noticed nothing unusual at rotation or during initial climb. We continued without incident. We updated the FMC with the correct ZFW. Had I compared the release tow with the load sheet takeoff weight, I would have caught this error.

Title: FLT CREW OF A B737-300 DEPARTS GATE AND PERFORMS A TKOF WITH INCORRECT TKOF WT, MISSING THE WT OF PAX ONBOARD AT MCI, MO.

Narrative: WE PUSHED FROM THE GATE ON TIME. WE WERE IN NO WAY RUSHED -- NEITHER WAS THE OPS AGENT FROM MY POINT OF VIEW. WE RECEIVED THE LOAD SHEET WITH AN OEW OF 72347 LBS, NOTHING IN TOTAL PAX WT, AFT HOLD WT OF 1098 LBS, OPERATIONAL WT OF 73445 LBS, AN ADJUSTMENT OF +201 LBS, AND FINAL ZFW OF 73646 LBS. THE FUEL WT WAS 16802 LBS, AND TKOF WT WAS 90448 LBS. I DID NOT NOTICE THAT NOTHING WAS ENTERED IN THE PAX WT LINE. I CALCULATED THE TKOF DATA USING THE OPC, AND USED SPDS OF V1-116, VR-116, V2-126, AND TRIM OF 4.8. WE TAXIED TO RWY 19R, AND TOOK OFF WITHOUT INCIDENT. CLBING THROUGH 10000 OR 15000 FT, I CALLED OPS TO RPT OUR TKOF AND PUSH TIMES. THE PERSON AT OPS RELAYED TO ME THAT THE OPS AGENT HAD NEGLECTED TO INCLUDE THE PAX WT ON THE LOAD SHEET. HE GAVE ME THE CORRECTIONS. THOUGH IT WAS A MOOT POINT, I RECALCULATED THE TKOF DATA, AND FOUND THE CORRECT SPDS WERE V1-123, VR-123, V2-132. THE CAPT (PF) SAID HE NOTICED NOTHING UNUSUAL AT ROTATION OR DURING INITIAL CLB. WE CONTINUED WITHOUT INCIDENT. WE UPDATED THE FMC WITH THE CORRECT ZFW. HAD I COMPARED THE RELEASE TOW WITH THE LOAD SHEET TKOF WT, I WOULD HAVE CAUGHT THIS ERROR.
