Chapter 1 

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: 
Chapter 1 

1-2 FM 4-20.112/TO 13C7-1-8 20 February 2009 

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. 
Chapter 2 

2-2 FM 4-20.112/TO 13C7-1-8 20 February 2009 

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-ABMMO-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. 

1 Glue two full 36- by 96-inch sheets of honeycomb together. Center them 12 inches from the 

front edge of the platform.

SECTION II-RIGGING A-22 CARGO BAGS 

DESCRIPTION OF LOAD 

7-17. The palletized load system can be moved from the drop zone and transported on a specially designed 

truck. Bulk supplies are lashed to the pallet, giving the load integrity for transport. The pallet has swivel 

rings along the sides for lashing the load. The pallet is lashed to the airdrop platform for low-velocity 

airdrop. The load shown consists of eight A-22 cargo bags. Adapt these procedures to rig other items of 

bulk supplies. Ammunition listed in FM 4-20.153/MCPR 4-11.3B/TO 13C7-18-41, as certified for lowvelocity airdrop, may be rigged using these procedures. The rigged load may not be more than 100 inches 

high. 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.
