SECTION IV- RIGGING AAFARS WITH SIX 500-GALLON FUEL DRUMS
DESCRIPTION OF LOAD
4-56. The Advanced Aviation Forward Area Refueling System (AAFARS) is rigged
on a 32-foot type, V platform with seven G-11 cargo parachutes. The AAFARS is
designed for forward area refueling of up to four aircraft at a time with a mini-
mum of 55 GPM. There are six collapsible fuel drums as an accompanying load.
Each drum is filled with 432 gallons of liquid. When empty, each drum weighs
250 pounds and is 62 inches long and 53 inches in diameter. The total rigged
overall length is 402 inches. Width is 108 inches. Height is 94 inches. Center of
balance is 195 inches.
Notes:
1. For drums filled with a liquid other than water, use Table 1-1 to
recompute the weight.
2. If the load varies from the one shaown, the weight, height, CB, tipoff
curve, and parachute requirements must be recomputed
3. Do not pressurize drums with air.
PREPARING PLATFORM
4-57. Prepare a 32-foot type V airdrop platform using two tandem links, eight
suspension brackets and 84 tie-down clevises as shown in Figure 4-78.
Notes: 1. The nose bumper may or may not be installed.
2. Measurements given in this section are from the front edge of
the platform, NOT from the front edge of the nose bumper.

6.
Install a suspension bracket to each platform side rail using holes 57, 58, and 59.
7.
Install a tie-down clevis to bushings 1 (doubled), 3, and 4 (doubled) on each front
tandem link.
8.
Install a tie-down clevis to bushings 1(doubled), 2, and 3 on each of the first
suspension brackets.
9.
Install a tie-down clevis to bushings 2 and 3 of each of the second suspension
bracket.
10. Install a tie-down clevis to bushings 2 (doubled), 3, and 4 of each of the fourth
suspension links.
11. Starting at the front of each platform side rail, install a tie-down clevis to the
bushings bolted to holes 9, 10, 17, 18, 20, 21, 29, 30, 32, 33 (tripled), 34, 41, 42
(tripled), 43, 49, 50, 55, 56 (doubled), 61, 63, 64 (doubled).
