5-3. Build the honeycomb stack for the first stack of ammunition and place it on the platform as shown in
Figure 5-2. Build the stack for the second stack of ammunition as shown in Figure 5-2. Set the second
honeycomb stack aside.
Notes.
1. When ammunition is dropped, two layers of honeycomb are required as shown in Figure 5-3.
2. When rigging this load for airdrop on a drop zone with ground elevation of 6,000 to 10,000 feet, add an
additional layer of honeycomb. However, the height of this load cannot exceed 100 inches.
3. Adjust the dimensions of the honeycomb to fit the items being dropped.
4. Do not cover the extraction bracket with honeycomb.

3. Install a tandem link to the rear of each platform side rail using holes 30, 31, and 32.
4. Install clevises on bushings 2 and 3 of each front tandem link.
5. Install clevises on bushings 1 and 3 of each rear tandem link.
6. Starting at the front of each platform side rail, install clevises on the bushings bolted to
holes 4, 6, 9, 10, 11, 12, 13, 15 , 16, 17, 18, 19, 20, 22, 23, 24, 25, and 29.
