ammunition loads. This manual is designed for all parachute riggers.
This publication applies to the Active Army, the Army National Guard (ARNG)/Army National Guard
of the United States (ARNGUS), and the United States Army Reserve (USAR) unless otherwise stated.

General Information
DESCRIPTION OF ITEMS
1-1. Bulk supplies consisting of rations, fuels, lubricants, ammunition, and various unit equipment can be rigged on
standard airdrop platforms using the procedures given in this manual. Items packaged in containers or units of the same
size, such as rations and ammunition are rigged using lashings and endboards. These procedures can be adapted for
loads that are different from the specific ammunition loads shown. Some items are more easily rigged in A-22
containers. Items of varying and irregular size can be padded, secured, and contained in mass supply boxes on 12, 16,
and 20-foot platforms. Additionally, items using endboards and A-22 containers are shown rigged using the palletized
load system (PLS).
CAUTION
The load weight may vary from the loads shown. Be sure that each
load weight, parachute requirements, CB, lashing effectiveness, and
tip-off curve computed according to FM
4-20.102/MCRP
4-
11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5.
SPECIAL CONSIDERATIONS
1-2. Special considerations for this manual are given below.
• The loads covered in this manual may include hazardous materials as defined in AFMAN(I) 24-204/TM 38-
250. If included, the hazardous materials must be packaged, marked, and labeled as required by AFMAN(I)
24-204/TM 38-250.
CAUTION
Only ammunition listed in FM 4-20.153/MCRP 4-11.3B/TO 13C7-18-41
may be airdropped.
• A copy of this manual must be available to the joint airdrop inspectors during the before- and after-loading
inspection.
AIR FORCE UNILATERAL LOADS
1-3. Air Force unilateral loads are used to support wing airdrop proficiency requirements. The loads are designed as
an alternative to actual rigged loads, using the procedures for rigging mass supplies on an 8-foot, type V platform.
Ballast for the unilateral platform loads normally consists of railroad ties, lumber or ammo boxes filled with dirt or
rocks, however any material may be used as long as it is sufficiently restrained. The following exceptions to FM 4-
20.102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5 and this manual are authorized for Air Force
unilateral loads only:

1-1
Chapter 1
CAUTION
The load weight may vary from the loads shown. Be sure that each
load weight, parachute requirements, CB, lashing effectiveness, and
tip-off curve computed according to FM
4-20.102/MCRP
4-
11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5.
• Honeycomb is not required under the ballast; however, due to the lack of honeycomb, the life span of the
type V platform may be reduced. Units must inspect the platform for cracks, loose rivets, delaminating
panels, and general damage prior to each drop. All loads must be re-rigged and re-inspected after each
airdrop according to TM 10-1670-268-20&P/TO 13C7-52-22.
• Honeycomb or a suitable substitute (felt covered plywood) must be used to provide a flat and stable surface
for the parachutes and releases.

Rigging Supply Loads on an 8-Foot, Type V Platform for
Low-Velocity Airdrop
SECTION I-RIGGING BULK SUPPLIES
DESCRIPTION OF LOAD
2-1. Bulk supplies consisting of rations, equipment, fuel, ammunition, or other items of general supply
are rigged on an 8-foot, type V airdrop platform with G-11 cargo parachutes. Items packaged or configured
so that they can be restrained by endboards and lashings can be airdropped using these procedures.
Modifications to the honeycomb, endboards, and lashings may be necessary to allow for items of different
sizes and shapes from those shown. For extraction purposes, the rigged load must weigh at least 2,520
pounds. Refer to FM 4-20.102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5 for the
weight limitations for the number of parachutes to be used.
PREPARING PLATFORM
2-2. Prepare an 8-foot, type V platform as shown in Figure 2-1.

Step:
1. Inspect, or assemble and inspect, an 8-foot, type V platform as outlined in TM 10-
1670-268-20&P/TO 13C7-52-22.
2. Install a tandem link to the front of each platform side rail using holes 1, 2, and 3.
3. Install a tandem link to the rear of each platform side rail using holes 14, 15, and 16.
4. Starting at the front of each platform side rail, install clevises on the bushings bolted to
holes 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13.
5. Starting at the front of the platform, number the clevises 1 through 10 on the right side,
and 1A through 10A on the left side.
6. Label the tiedown rings according to FM 4-20.102/MCRP 4-11.3J/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5.

PLACING HONEYCOMB
2-3. Place the honeycomb on the platform as shown in Figure 2-2.
Notes.
1. When ammunition is dropped, two layers of honeycomb are required.
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.
3. Adjust the dimensions of the honeycomb to fit the items being dropped.
4. Do not cover the extraction bracket with honeycomb.
2
1
1 Glue two full 36- by 96-inch sheets of honeycomb together. Center them 12 inches from the
front edge of the platform.
2 Make a stack as in step 1 above and place it flush against the stack placed in step 1.

POSITIONING AND SECURING LOAD
2-4. Place four 30-foot lashings on the honeycomb, place the load on the honeycomb, and secure the
lashings as shown in Figure 2-3. Adapt the procedures shown for loads configured differently.
CAUTION
Only ammunition listed in FM 4-20.153/MCRP 4-11.3B/TO 13C7-18-
41 may be airdropped. Hazardous material must be packaged,
marked, and labeled as required by AFMAN(I) 24-204/TM 38-250.

CONSTRUCTING AND INSTALLING ENDBOARDS
2-5. Construct the endboards and install them on the load as shown in Figure 2-4.
Notes.
1. This drawing is not to scale.
2. All dimensions are in inches.
3. The dimensions of the endboards will vary, depending on the load being rigged. The
endboards must be even with the top of the load.

1 Construct two endboards using one 3/4- by 28- by 96-inch piece of plywood for each
endboard. Make cutouts as shown.
Note. Tape or pad the cutouts in the endboards to protect the lashings from sharp edges.

SECTION II-RIGGING BULK SUPPLIES IN A-22 CARGO BAGS
DESCRIPTION OF LOAD
2-16. Bulk supplies consisting of rations, equipment, fuel, ammunition, or other items of general supply
are rigged on an 8-foot, type V airdrop platform with G-11 cargo parachutes. Items are packaged or
configured so that they can be contained in A-22 cargo bags and can be airdropped using these procedures.
For extraction purposes, the rigged load must weigh at least 2,520 pounds. Refer to FM 4-20.102/MCRP 4-
11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5 for the weight limitations and for the number of
parachutes to be used.
PREPARING PLATFORM
2-17. Prepare an 8-foot, type V platform as described in paragraph 2-2 and as previously shown in Figure
2-1.
PLACING HONEYCOMB
2-18. Place the honeycomb on the platform as shown in Figure 2-14.
Notes.
1. When ammunition is dropped, two layers of honeycomb are required.
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.
