## 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).

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 TM 38-
250/AFMAN(I) 24-204. If included, the hazardous materials must be packaged, marked, and
labeled as required by TM 38-250/AFMAN(I) 24-204.

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:


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.

# Chapter 2 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.

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.
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.



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 TM 38-250/AFMAN(I) 24-204.

1
Form four 30-foot lashings according to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5. Center a lashing across the honeycomb 6 inches from each end.
2
Center two lashings on the joint in the honeycomb, 12 inches apart.
3
Position the load on the honeycomb with the weight evenly distributed.
4
Pass both ends of each lashing to the top of the load. Secure each lashing with two D-rings
and a load binder.


## 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.


Note. Loads longer than the one shown may be secured in this way, if the lashings are prepositioned under the honeycomb and endboards, and secured at both ends to the tiedown rings as shown in steps 4 and 5. Do not cover the extraction bracket.



2
Place one endboard against the front of the load.
3
Place one endboard against the rear of the load.
4
Pass the free end of a 15-foot lashing through tiedown ring A4 and through its own D-ring.
Pull the free end of the lashing over the top of the load.
5
Pass the free end of a 15-foot lashing through tiedown ring D4 and through its own D-ring.
Pull the free end of the lashing over the top of the load.
6
Secure the end of the lashing positioned in step 4 to tiedown ring A1 with a D-ring and a load
binder.
7
Secure the end of the lashing positioned in step 5 to tiedown ring B1 with a D-ring and a load
binder.

## Installing Lashings

2-6. Lash the load to the platform according to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5 and as shown in Figures 2-5 through 2-7.

# Chapter 3 Rigging Supply Loads On A 12-Foot, Type V Platform For Low-Velocity Airdrop

## Description Of Load

3-1. Bulk supplies consisting of rations, equipment, fuel, ammunition, or other items of general supply are rigged on a 12-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 3,780
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

3-2. Prepare a 12-foot, type V platform as shown in Figure 3-1.

1. Inspect, or assemble and inspect, a 12-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 22, 23, and 24.
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, 15, 16, 17, 18, 19, 20, and 21.
5. Starting at the front of the platform, number the clevises 1 through 14 on the right side,
and 1A through 14A 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

3-3. Place the honeycomb on the platform as shown in Figure 3-2.

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 16 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.
3
Make a stack as in step 1 above and place it flush against the stack placed in step 2.


## Positioning And Securing Load

3-4. Place six 30-foot lashings on the honeycomb, place the load on the honeycomb, and secure the lashings as shown in Figure 3-3. Adapt the procedures shown for loads configured differently.

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 TM 38-250/AFMAN(I) 24-204.

1
Form six 30-foot lashings according to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5. Center a lashing across the honeycomb 6 inches from each end.
2
Center two lashings on the joint in the honeycomb, 12 inches apart.
3
Position the load on the honeycomb with the weight evenly distributed.
4
Pass both ends of each lashing to the top of the load. Secure each lashing with two D-
rings and a load binder.

## Constructing And Installing Endboards

    3-5. Construct the endboards and install them on the load as shown in Figure 3-4.

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.


Note. Loads longer than the one shown may be secured in this way, if the lashings are prepositioned under the honeycomb and endboards, and secured at both ends to the tie-down rings as shown in steps 4 and 5. Do not cover the extraction bracket.

2
Place one endboard against the front of the load.
3
Place one endboard against the rear of the load.
4
Pass the free end of a 15-foot lashing through tie-down ring A6 and through its own D-ring.
Pull the free end of the lashing over the top of the load.
5
Pass the free end of a 15-foot lashing through tie-down ring D6 and through its own D-ring.
Pull the free end of the lashing over the top of the load.
6
Secure the end of the lashing positioned in step 4 to tie-down ring A1 with a D-ring and a
load binder.
7
Secure the end of the lashing positioned in step 5 to tie-down ring B1 with a D-ring and a
load binder.

## Installing Lashings

3-6. Lash the load to the platform according to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5 and as shown in Figures 3-5 through 3-7.

# Chapter 4 Rigging Forward Area Surgical Team (Fast) Equipment On A 12-Foot, Type V Platform For Low-Velocity Airdrop

## Description Of Load

4-1. The FAST equipment is rigged as a bulk supply load on a 12-foot, type V airdrop platform with G-
11 cargo parachutes. These procedures may be used to rig other bulk supply loads consisting of rations, equipment, fuel, lubricants, ammunition or other items of general supply. As load weights can vary widely, the parachute requirements must be computed for each load. For extraction purposes, the rigged load must weigh at least 3,780 pounds. Refer to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO

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 30, 31, and 32.
4. Install clevises on bushings 2, 3, and 4 of each front tandem link.
5. Install clevises on bushings 1, 2, 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 5, 6, 7, 11, 15, 16, 17, 18, 22, 26, 27, and 28. Install triple clevises on holes 9, 12, 14, 19, 21, and 24 according to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-
010/TO 13C7-1-5.
7. Starting at the front of the platform, number the clevises 1 through 30 on the right side, and
1A through 30A on the left side.
8. Label the tiedown rings according to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5.
Note. Refer to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5 (Table 2-

## Building Honeycomb Stacks And Placing First Stack

    5-35. Build the honeycomb stack for the first stack of ammunition and place it on the platform according
    to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5 and as shown in Figure 5-
    27. Build the stack for the second stack of ammunition as shown in Figure 5-27. Set the second honeycomb
    stack aside.


1
Center two 15- by 75-inch pieces of honeycomb lengthwise on the platform, 19 inches
from the front edge.
2
Place two 36- by 75-inch pieces of honeycomb flush on each side of the pieces placed in
step 1.
3
Center a 30-foot lashing 10 inches from each end of the honeycomb.
4
Center a 30-foot lashing 26 inches from the front edge of the honeycomb, and another 30-
foot lashing 26 inches from the rear.

## Positioning And Securing First Ammunition Stack

5-36. Set 120 boxes of 20-mm ammunition on the honeycomb and pre-positioned lashings. Secure the lashings as shown in Figure 5-28.

1
Set 40 boxes of ammunition on the honeycomb.
2
Place one layer of honeycomb cut to the dimensions in Figure 5-27, steps 1 and 2, over
the boxes.
3
Place 40 boxes of ammunition over the honeycomb placed in step 2.
4
Place a layer of honeycomb over the second layer of boxes.
5
Place a third layer of boxes over the honeycomb placed in step 4.
6
Secure each of the pre-positioned lashings in Figure 5-27, steps 3 and 4, on top of the
boxes with two D-rings and a load binder.

## Constructing And Placing Endboards

5-37. Construct four endboards and place them as shown in Figure 5-29.

The endboards must be the same height as the ends of the load.

Notes.
1. This drawing is not to scale
2. All dimensions are in inches.


1
Cut two 3/4- by 48- by 90-inch and two 3/4- by 6- by 90-inch pieces of plywood. Nail the four pieces flush together so that a single piece of 1 1/2- by 54- by 90-inch plywood results. Construct three other endboards the same way.
Note. On the endboard shown, the 6-inch piece is at the bottom. On the other side of the endboard shown, the
6-inch piece is at the top.

2
Make 2- by 3-inch cutouts as shown. Pad all cutouts with cellulose wadding and tape.
3
Place an endboard against the front of the boxes and place one against the rear. Tie them in place with a length of type III nylon cord.


## Lashing First Ammunition Stack And First And Second Endboards

# Rigging 155-Millimeter (Mm) Ammunition Modular Artillery Charge System Package (Macs Pac) On A Type V Platform For Low-Velocity Airdrop

## Section I-Rigging The Macs Pac On An 8-Foot, Type V Platform Description Of Load

8-1. Forty-eight 155-millimeter projectiles, twenty-four (M231) powder canisters and six fuse cans are rigged for low-velocity airdrop on an 8-foot, type V airdrop platform. The load uses two G-11B cargo parachutes.

Notes.
1. The load shown is using metal crates. However, wooden crates may be used with three
lashings and a load binder.
2. If the metal locking rods are missing, three lashings, D-rings and load binders will be needed.

## Preparing Platform

8-2. Prepare an 8-foot, type V platform as shown in Figure 8-1.



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. Install clevises on bushings 1, 2 and 3 of each front tandem link. 5. Install clevises on bushings 3 and 4 of each rear tandem link. 6. Starting at the front of each platform side rail, install clevises on the bushings bolted to
holes 4 (triple clevis), 5, 8 (triple clevis), 10, 11, 12, and 13.
7. Starting at the front of the platform, number the clevises 1 through 14 on the right side, and
1A through 14A on the left side.
8. Label the tiedown rings according to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5.

## Building Honeycomb Stacks

8-3. Prepare honeycomb stack 1 as shown in Figure 8-2.


Notes. 1. This drawing is not to scale. 2. All dimensions are in inches. 3. Leave 4 1/2 inches between the 15- by 5-inch and 15- by 10-inch honeycomb stacks.

Note. Do not glue the 15- by 5 and 15- by 10-inch honeycomb stacks to the base stack. Slight adjustments may be necessary as you place the projectiles.


Notes. 1. This drawing is not to scale. 2. All dimensions are in inches.

## Positioning Lashings On The Platform

8-4. Position eight 15-foot lashings according to FM 4.20-102/MCRP 4-11.3J/NAVSEA SS400-AB-
MMO-010/TO 13C7-1-5 and as shown in Figure 8-3.

1
Pass a 15-foot lashing through tie-down ring A1 and back through its own D-ring. Run the
lashing off the front edge of the platform and S-fold the excess.
2
Repeat for tie-down ring B1, A2 and B2.
3
Pass a 15-foot lashing through tie-down ring A3 and back through its own D-ring. Run the
lashing off the rear edge of the platform and S-fold the excess.
4
Repeat for tie-down ring B3, B4 and C4.

## Positioning The Honeycomb Stack On The Platform

    8-5. Position the honeycomb stack as shown in Figure 8-4.



Note. When positioning the honeycomb, stack ensure the bolts and nuts of the platform extraction bracket are not covered.

1
Position the honeycomb stack 4 inches from the front edge of the platform and centered.


## Positioning And Securing The Ammunition Stack

8-6. Position and secure the first ammunition stack as shown in Figure 8-5.

1
Tie the four center eyelets of each bundle together with 1-inch tubular nylon webbing.
Secure with a surgeon's knot locking knot and cover with cloth backed tape. Use for lifting
purposes only.

Note. The racks of projectiles will need three lashings if the locking pins of the racks are missing.


2
Position three sets of projectiles flush on the honeycomb on each side (48 total). Fit the
skids at the bottom of the bundles into the slots in the honeycomb stack.
3
Route the pre-positioned lashing from tie-down ring A2 over the top of the right stack of 155-mm
projectiles at the front of the load. Route the pre-positioned lashing from tie-down ring A3 over the top of the right stack of 155-mm projectiles at the rear of the load. Secure the lashings on top using two D-rings and a loadbinder.
4
Route the pre-positioned lashing from tie-down ring B2 over the top of the left stack of 155-mm
projectiles at the front of the load. Route the pre-positioned lashing from tie-down ring B3 over the top of the left stack of 155-mm projectiles at the rear of the load. Secure the lashings on top using two D-
