Narrative:

We received bag weights from ramp as 696 pounds in compartment 1 and 494 pounds in compartment 2. With these weights and the 33 adult passenger, we had an index of -3.2. Our weights were ZFW of 26010 pounds, ramp 28910 pounds, takeoff 28701 pounds, and landing 28021 pounds. It was required to use procedures to remove the tail-stand from aircraft. After arrival at destination and conferring with station personnel, we determined none of the baggage was calculated over the standard weights, which they should have been. After departure, the departure station calculated the actual bag weights using a scale. It was determined that out of 45 checked bags, only 6 bags met the standard weights. The actual total weight was 1883 pounds, a 693 pound difference. This means that our actual ZFW was 26703 pounds, ramp 29603 pounds, takeoff 29394 pounds and 28714 for landing. It also means our actual center of gravity index was over plus 4.0 (+4.2 estimated) which is completely out of the aft limit. With heavy loads to military bases, we need to know that weights are being estimated in a reasonable manner, otherwise safety is being compromised.

Title: AN SF3 CAPT RPTED THAT, DURING A MIL CONTRACT FLT, THE WTS USED FOR EACH BAG EXCEEDED WHAT WAS USED BY LOAD PLANNING, CAUSING HIM TO FLY OUT OF THE AFT LIMIT.

Narrative: WE RECEIVED BAG WTS FROM RAMP AS 696 LBS IN COMPARTMENT 1 AND 494 LBS IN COMPARTMENT 2. WITH THESE WTS AND THE 33 ADULT PAX, WE HAD AN INDEX OF -3.2. OUR WTS WERE ZFW OF 26010 LBS, RAMP 28910 LBS, TKOF 28701 LBS, AND LNDG 28021 LBS. IT WAS REQUIRED TO USE PROCS TO REMOVE THE TAIL-STAND FROM ACFT. AFTER ARR AT DEST AND CONFERRING WITH STATION PERSONNEL, WE DETERMINED NONE OF THE BAGGAGE WAS CALCULATED OVER THE STANDARD WTS, WHICH THEY SHOULD HAVE BEEN. AFTER DEP, THE DEP STATION CALCULATED THE ACTUAL BAG WTS USING A SCALE. IT WAS DETERMINED THAT OUT OF 45 CHKED BAGS, ONLY 6 BAGS MET THE STANDARD WTS. THE ACTUAL TOTAL WT WAS 1883 LBS, A 693 LB DIFFERENCE. THIS MEANS THAT OUR ACTUAL ZFW WAS 26703 LBS, RAMP 29603 LBS, TKOF 29394 LBS AND 28714 FOR LNDG. IT ALSO MEANS OUR ACTUAL CTR OF GRAVITY INDEX WAS OVER PLUS 4.0 (+4.2 ESTIMATED) WHICH IS COMPLETELY OUT OF THE AFT LIMIT. WITH HVY LOADS TO MIL BASES, WE NEED TO KNOW THAT WTS ARE BEING ESTIMATED IN A REASONABLE MANNER, OTHERWISE SAFETY IS BEING COMPROMISED.
