## Chapter 1 General Rigging Information Humanitarian Airdrop Loads Section I - Description Of Humanitarian Loads Humanitarian Airdrop Methods

1-1. Humanitarian airdrop utilizes the Container Delivery System (CDS), some variation of the system, or TRIADS, a special method of free drop.  Many factors can influence the delivery method used.

- **EXTENDED TRI-WALL AERIAL DELIVERY SYSTEM (TRIADS).** The TRIADS system is a
corrugated tri-wall box rigged for static line deployment off the ramp of an aircraft using CDS
procedures. Typical loads include loose Meals-Ready-to-Eat (MREs) or Humanitarian Daily
Rations (HDRs).  Following deployment the caps of the box separate from the sleeve allowing the container's content to scatter and freefall to the ground. TRIADS has a 1,375 pound load capacity. Chapter 2 if this manual covers rigging TRIADS for airdrop.
- **LOW-COST AERIAL DELIVERY SYSTEM (LCADS).** LCADS is a modified, lightweight A-22
system with no scuff pad, cover, or friction adapters on the lateral bands.  It is rigged like a high velocity A-22 load, but uses one of several special parachutes. LCADS is used for high-volume delivery of non-fragile items where airdrop is not recoverable. LCADS has a 2,200 pound capacity.
- **DOUBLE A-22 CONTAINER.**  The double A-22 container consists of two A-22 sling assemblies.
The covers may or may not be used.  Only six of the suspension webs are used. The double A-22 cargo bag has a 3,375 pound load capacity. Chapter 4 of this manual covers rigging the double A- 22 cargo bag.
- **QUADRUPLE A-22 CONTAINER.**  The quadruple A-22 container consists of four standard A-22
sling assemblies which can be laced together to form one large container, or can be individually
rigged and then configured side-by-side for unitized delivery of four loads. The quadruple A-22 cargo bag has a 4,375 pound load capacity. Chapter 5 of this manual covers rigging the quadruple A-22 container.

## Section Ii - Parachute Requirements And Packing Procedures Parachute Requirements

1-2. Special considerations for this manual are given below.
- **EXTENDED TRI-WALL AERIAL DELIVERY SYSTEM (TRIADS)**. There is no parachute
used for TRIADS. The TRIADS uses the free drop method.
- **LOW COST AERIAL DELIVERY SYSTEM (LCADS).** LCADS employs a 26-foot low cost
parachute for high-velocity (HV) airdrop. The 26-foot low cost parachute is made from more readily available and more economical materials than the standard 26-foot ringslot parachute except the low cost parachute is designed for reuse. The low cost parachute is pre-packed and ready to attach to the load.  Like the standard 26-foot parachute, the low cost parachute is
deployed using a breakaway static line for high altitude operations. The 26-foot low cost parachute can support suspended weights from 501 to 2,200 pounds.
- **DOUBLE A-22 CONTAINER.**  The double A-22 container employs a reefed G-12 parachute with
both skirt and vent reefing.  The reefing of the G-12 parachute provides for high-velocity ballistics similar to the standard HV CDS.  A standard 68-inch pilot parachute is used to deploy the reefed G-12 and a breakaway static line is used to deploy the 68-inch pilot parachute.  The reefed G-12
parachute can support suspended weights from 2,201 to 3,375 pounds.  The reefed G-12 and 68- inch pilot parachutes are packed according to Chapter 1, Section II, paragraphs 1-3 through 1-5 of
this manual.
- **QUADRUPLE A-22 CONTAINER.**  The quadruple A-22 container employs the same reefed G-12
parachute (skirt and vent reefing) that is used with the double A-22 container.  A standard 68-inch
pilot parachute is also used to deploy the reefed G-12 and a breakaway static line is used to deploy
the 68-inch pilot parachute.  When the reefed G-12 parachute is used with the quadruple A-22 it can support suspended weights from 3,375 to 4,375 pounds.  The reefed G-12 and 68-inch pilot parachutes are packed according to Chapter 1, Section II, paragraphs 1-3 through 1-5 of this
manual.

## Packing The Reefed G-12 And 68-Inch Diameter Pilot Parachutes

1-3.
The packing procedures for the reefed G-12 parachute are described below.
- **PREPARING PARACHUTE FOR PROPER LAYOUT**. Prepare parachute for proper layout in
accordance with TM 10-1670-281-23&P.
- **SERVICING THE CANOPY VENT**.  Service the canopy vent in accordance with TM-10-1670-
281-23&P. The wrap of type II cotton muslin cloth is not necessary if dropping for one-time use. If not used, the canopy vent lines should still be tied off with two turns single of 14-inch, type I cotton webbing.
- **REEFING THE CANOPY VENT**. Remove the bridle loop from the stationary post. With a sharp
rigging knife, cut a small slit (approximately 1 12 inches in length) in the gore material of every fourth gore, directly below the upper lateral band, as shown in Figure 1-1.



Route a 4-foot long vent reefing line made of 1-inch tubular nylon from the outside of the gore into the first gore hole as shown in Figure 1-2. Alternate material for the vent reefing line is 1 23/32-inch wide, type VIII
nylon webbing or one turn triple of 9/16-inch tubular nylon.


Run the line to the right, over the upper lateral band and down into the next gore hole as shown in Figure 1-3. Follow Figure 1-1 for cutting gore holes every fourth gore. Repeat this procedure until the vent reefing line has run through all 16 gore holes.

Pull the vent reefing line tight to close off the vent. Tie the two running ends of the vent reefing line together with a surgeon's knot and locking knot, and overhand knots in the running ends. Trim each running end at a point 2-inches from the surgeon's knot and locking knot as shown in Figure
1-4.

## Applying Tension

1-4.

Apply tension in accordance with TM 10-1670-281-23&P.

## Folding The Gores And Reefing The Canopy Skirt

1-5. Position the large line separator, throw the right suspension line group over the left group of gores and lines, and position the large pedestal fan in accordance with TM-10-1670-281-23&P.

- Lay out a single 47-foot length of 1 tubular nylon webbing or a doubled 47-foot length of 1-inch
tubular webbing. Remove twists and apply a small amount of tension (just enough to remove slack).  While under tension, measure 2 feet in from both ends and mark the tubular nylon.  Fold the webbing length back unto itself and line up the marks.  While holding the marks together, pull the line out straight, apply a small amount of tension, and locate and mark the center of the line. This tubular nylon length will be the skirt of the reefing line.
Note: When fabricating the skirt reefing lines in large quantities, recommend marks on the floor or on a packing table be made at 2 feet, 23 12 feet, 45 feet and 47 feet.  Use these marks to assist in marking or cutting reefing lines.  All measurements should be within  1 inch.

- Route one free running end of the skirt reefing line down through the right side of the suspension
line 33 pocket band, behind suspension line 33, and back up through the left side of the pocket band.  Pull the line through until the center mark on the skirt reefing line is lined up with
suspension line 33 as shown Figure 1-5.  Tie a temporary slip knot in the reefing line onto suspension line 33 to keep the reefing line from moving off the mark.

Begin to fold the right gore group (lines 33 through 64) in accordance with the TM procedures. As each suspension line is passed over, route the
reefing line through the pocket band, behind the suspension line and back up through the pocket band of the suspension line being passed over in the
same manner as shown in Figure 1-5. Repeat for every suspension line, leaving about 8 inches of slack in the reefing line between each suspension line.  Tie a temporary slip knot in the end of the skirt reefing line onto suspension line 64 to keep the reefing line from slipping out of position.

Throw the left group of gores over the folded right group of gores.  Untie the temporary slip knot in the reefing line on suspension line 33.  Fold the left gore group (lines 32 through 1) in accordance with the TM and route the other end of the reefing line through pocket bands 32 through 2 and behind suspension lines 32 through 2 in the same manner as lines 33 through 64.

Untie the temporary slip knot in the reefing line on suspension line 64.  Run both ends of the reefing line down through pocket band 1 and behind suspension line 1.

link assemblies.  The break cord tie will be IAW the instructions in the first subparagraph below. Stow the canopy, suspension lines and risers, and close the deployment bag  in accordance with TM
10-1670-281-23&P.
 Connect the G-12 deployment bag bridle to the parachute apex loop with a 60-inch strap as shown in
Figure 1-7. This is necessary to keep the 68-inch pilot parachute permanently attached to the apex
of the canopy. The following alternate materials are authorized for use for the 60-inch strap:

A 60-inch loop, single turn of type VIII nylon webbing.

A 60-inch loop, single turn of 1-inch tubular nylon webbing.

A 60-inch loop, single turn of 34 - inch tubular nylon webbing.

A 60-inch loop, one turn double of 9/16 tubular nylon webbing.

The standard 60-inch connector strap, without using L-bar connector links.
Note: When installing the 60-inch connector strap without using the L-bar connector links, use the same materials and number of turns shown above to connect one end of the strap to the bag bridle and one end to the apex loop. Use the length required to tie the strap, leaving no slack between the strap and the bridle, or the strap and the apex loop.

-
The ties defined in the above paragraph must be tied at the bag bridle center loop as follows:  Run the material through the apex loop, pass the running ends through the top of the deployment bag and then through the bag bridle center loop from opposite directions.  Tie the first part of a surgeon's knot inside the center loop, then tie two double overhand knots on the outside of the center loop with knots in the running ends. Tape the 60-inch loop at the apex loop and the bag bridle center loop using several turns of cloth duct tape. When tying the 60-inch connector strap without using the L-Bar connector links, use the same tie as described at both the apex loop and the bag bridle center loop.

Packing and Rigging the 68-inch Diameter Pilot Parachute. Pack and rig the 68-inch
pilot parachute for breakaway in accordance with TM 10-1670-281-23&P, except the static line
breakcord tie will be made as follows:  Cut a 24-inch length of 14-inch type I cotton webbing (in lieu of the standard type of III nylon).  Fold the length of cotton webbing in half and pass it
through the clevis and insure the running ends are aligned.  Pass each running end of the cotton webbing through the static line attaching loop from opposite directions forming a 4-inch loop of one turn double between the clevis pin and the attaching loop as shown in Figure 1-8.  Secure the cotton webbing ends on top of the static line attaching loop with a surgeon's knot and a locking knot.  Trim each running end at a point 2 inches from the surgeon's knot and locking knot.

## Positioning Pilot Parachute

1-6. Place the packed pilot parachute on top of the G-12 deployment bag bridle assembly. Use a single loop of ticket number 8/7 cotton thread to secure the pilot parachute onto the reefed G-12 parachute in two places. The first loop of ticket number 8/7 cotton thread will be routed through the pilot parachute D-bag tiedown loops on one side of the pilot parachute D-bag and through the same two tiedown loops on one side of the G-12 bag that are normally used to tie the pilot D-bag. The other loop will be secured in the same manner on the opposite side as shown in Figure 1-9.

## Chapter 2 Rigging Extended Tri-Wall Aerial Delivery System (Triads) Section I - General Rigging Information For Extended Triads Triad System Components

2-1. The TRIAD system, shown in Figure 2-1, is constructed from corrugated tri-wall cardboard.  An 80-
inch tall sleeve is enclosed by two 12-inch tall end caps. A vertical strap with break cord secures the load for transport. The static line, rigged to the break cord, releases the end caps after deployment from the aircraft permitting the contents of the load to free-fall to the ground.

## Triads Skid Board

2-2. The skid board is made of 14- by 48- by 40-inch plywood.  If 14 -inch plywood is not available, 3/16
or 5/16-inch plywood may be substituted. The skid board will be secured to the container using glue and 1-
inch staples.

## Triads Container Limitation

2-3. The TIADS container has a weight restriction of 747 to 1,375 pounds.  Ensure that the load weighs a minimum of 28 pounds per square foot IAW FM 4-20.103/MCRP 4-11.3C/TO 13C7-1-11.



## Caution

When dropping MREs or HDRs the maximum load is dependent on the drop altitude.  Refer to Table 2-1 for the system capacity.

## Assembly Line Rigging

2-4. When assembly line rigging is used for TRIADS loads, six stations are needed.  The stations are:
preparing the caps, preparing honeycomb and skid board, assembly, filling container, strap and static line installation, and final inspection.



## Inspection Of Load

2-5. The TRIADS load must be inspected by a qualified rigger.  While being rigged this load should be supervised or rigged by a parachute rigger.  DD Form 1748-1 (Joint Airdrop Inspection Record [Containers]) must be completed before airdrop.



## Parachute Used

2-6. No parachute is used for this system.



## Aft Restraint

2-7. Release gate suspension loops and additional honeycomb kits are required for TRIADS containers at pre-determined release gate locations in the aircraft.  Prepare the honeycomb and straps as shown in Figure 2-6.


Note: Installation of the release gate suspension loops and the honeycomb kit must be completed prior to filling the container with MREs and HDRs.



## Section Ii - Rigging Extended Triads Containers System Description

2-8. The TRIAD System is a corrugated tri-wall box rigged for static line deployment off the ramp of an aircraft.  Typical loads include loose MREs or HDRs.  Following deployment, the caps of the box separate from the sleeve allowing the container's content to scatter and free-fall to the ground.

## Preparing Items And Skid Board

2-9. Refer to paragraph 2-2 for preparation of the skid board.  HDRs or MREs must be removed from their shipping containers before loading.

## Preparing Honeycomb Base

2-10. Prepare the honeycomb base as shown in Figure 2-2.  The honeycomb layers will be glued together but not to the base cap.

1
Cut two pieces of honeycomb 36- by 46-inches and two pieces of honeycomb 16- by 36-
inches.
2
Glue the two 36- by 46-inch pieces of honeycomb together aligning the corners and edges.
3
Glue the two 16- by 36-inch pieces of honeycomb along the 36 inch long edges of the sheets
leaving a 14-inch space.

## Preparing Straps And Static Line

2-11. Prepare the straps and static line as described below.

-
Cut one length of type VIII nylon webbing 288 inches long.  Measure 20 inches from both ends and
place a mark. Fold the type VIII nylon webbing at the 20 inch marks and place a double overhand
knot, forming a 4-inch loop in the ends. Place an overhand knot in the running ends.
-
Cut one length of type III nylon cord, 36 inches long and remove the core threads.
-
Cut one length of 1 inch tubular nylon webbing 228 inches long.  Measure 15 inches from one end of the nylon and place a mark. Fold the 1 inch tubular nylon webbing at the mark and tie a double
overhand knot to form a 4 inch loop. Tie an overhand knot in the running end. Install a G-14 clevis in the loop. From the opposite end of the 1 inch tubular nylon webbing, measure 24 inches and make a mark.
-
Cut four pieces of type VIII nylon webbing (1/2 tubular webbing may be used as a substitute) 40
inches long.
-
Cut two pieces of 1 inch tubular nylon webbing 36 inches long.

## Preparing End Caps

2-12. Prepare the straps and static line as described.

1
Form the tri-wall cap by folding all end and side flaps in towards the center.
2
Use an Air Stapler (Bostitch D3AD) or equivalent and secure the tab on each corner to the
adjacent side flap assuring that the corner is square as shown above.  If stapler is not
available, cloth packed tape may be used.  Note that the tab should be on the outside of the cap.  Approximately three staples should be used for each corner.  It is not necessary for the staples to fully penetrate both layers of the tri-wall container.
3
Repeat process to form the two caps necessary for the system.

## Installing Skid Board

2-13. Install the skid board on the base cap as shown in Figure 2-4.

1
Apply glue to one side of skid board as shown above and press it onto base cap.
2
Tip the base cap down so that it sits on the plywood skid board.  Lay the type VIII strips
prepared in paragraph 2-11 bullet 4 equally spaced across the inside bottom of the cap.
3
Using a pneumatic staple gun (Senco L13 or equivalent) with 1 inch staples, staple through
the nylon webbing, cap, and into plywood skid board.  Apply adequate pressure to ensure that the plywood is tightly secured to the base cap.  Staples should be spaced approximately every 6 inches down the length of the nylon webbing.

## Caution

When attaching skid board to the load using staples, apply adequate pressure to ensure that the connection is tight and secure.  However, staple ends must penetrate through the bottom of the skid board.

## Assembling The Box

2-14. Assemble the TRIADS container as shown in Figure 2-5.

## Gate Suspension Loops And Honeycomb Kit

2-15. TRIADS containers located at release gate locations must have release gate suspension loops installed and honeycomb reinforcement positioned inside the box. Construct and install the release gate suspension loops and honeycomb as shown in Figure 2-6.

## Filling The Triads Container

2-16. Fill the box with the appropriate weight of HDRs or MREs. Table 2-1 must be used to determine the maximum weight for the drop altitude. Once filled, install the end cap over the top of the sleeve.

1
Center the honeycomb in base as shown above.
2
Slide the 80 inch high sleeve over the honeycomb and inside the base cap.
3
If the container is located at a release gate location, gate suspension loops and honeycomb
reinforcement must be positioned inside the box before it is filled (see Figure 2-6).
1
In order to install the release gate suspension loops, four 1-inch square holes must be cut in
one of the 48-inch wide sides as shown above.  The holes should be 6-inches apart and
located between 4 and 6 inches inboard of the box corners and at or near the vertical center of the box.
2
Using the 36-inch tubular nylon straps prepared in paragraph 2-11, loop the nylon through
the holes as shown above.  Tie the ends of the 1-inch tubular with a surgeon's knot and
locking knot with overhand knots in the running ends.
3
Slide the 1-inch tubular so that the knots are inside the box as shown above.
4
Cut two pieces of honeycomb 71-inches by 47-inches and two pieces 71-inches by 34-
inches.  Slide the honeycomb against the inside wall of the sleeve.  The honeycomb should
be flush with the top of the sleeve.

## Chapter 3 Rigging Low Cost Aerial Delivery System (Lcads) Section I - General Information For Lcads Lcads System Components

3-1. The LCADS shown in Figure 3-1 employs a low cost version of the A-22 sling assembly and low cost version of the 26-foot ringslot parachute that can be readily procured if needed.  The low cost sling assembly uses a more readily available and more economical material and eliminates much of the hardware as compared to the standard A-22 sling assembly.

## Lcads Skid Board

3-2. Like the standard high velocity CDS, the sling assembly is secured to a 34- or 1- by 48- by 48-inch plywood (Grade AC) skid board with 12-inch tubular nylon webbing.  Honeycomb is positioned between the container and the skid board for impact cushioning.

## Lcads Container Limitations

3-3. The LCADS container has a weight restriction of 501 to 2,200 pounds.  However, it is recommended that the maximum load be limited to 1,750 to insure load survivability.

## Inspection Of Load

3-4. The LCADS load must be inspected by a qualified rigger. While being rigged this load should be supervised or rigged by a parachute rigger.  DD Form 1748-1 must be completed before airdrop.

## Parachute Used

3-5. LCADS employs a 26-foot HV low cost parachute. The 26-foot low cost parachute performs identically to the standard 26-foot HV parachute except the low cost parachute is designed for one-time use, whereas the standard 26-foot HV is designed for reuse.  The low cost parachute may be pre-packed and ready to attach to the load.  The standard 26-foot HV parachute may be used if the low cost is not available.

## Section Ii - Rigging High Velocity Lcads System Description

3-6. The LCADS System is rigged as a typical A-22 high-velocity load. Typical loads include rations, water, and other small items.  LCADS container loads must weigh at least 501 pounds but not exceed
2,200 pounds, excluding the weight of the parachute. The load is rigged with a 26-foot low cost parachute.

## Preparing Items And Skid Board

3-7. Refer to Figure 3-2 for preparation of the skid board.  Prepare the drop items according to the load's sensitivity.  Items must be well padded to prevent damage during airdrop.


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

1
Place a 34- or 1- by 48- by 48-inch piece of plywood on a flat surface.

Note. Loads up to 1,600 pounds may use 34-inch plywood, loads that exceed 1,600 pounds must use 1-inch.

2
Drill four 12-inch holes on each side as shown above.

3
Measure 3 inches in from each corner of the skid board and make a cut diagonally.
4
Cut eight 10-foot lengths of 12-inch tubular nylon webbing.  Route one length through hole A from the
bottom and the other end through hole B from the bottom.  Even the ends.
5
Repeat step 3 for holes C and D and remaining sides.


## Preparing And Placing Honeycomb

3-8. Prepare and place the honeycomb as shown in Figure 3-3. Note. This drawing is not to scale.

1
Center a 36- by 44-inch and an 8- by 44-inch piece of honeycomb side by side on the skid
board. Make sure the layer is 2 inches in from all sides.
2
Cut three 8- by 44-inch pieces of honeycomb. Center one piece on top of the first layer of
honeycomb. Place one piece of honeycomb even with each side edge.
3
Center a 36- by 48-inch and 12- by 48-inch piece of honeycomb side by side on top of the
second layer of honeycomb.
4
Cut three 12- by 48-inch pieces of honeycomb. Center one piece on top of the third layer of
honeycomb. Place one piece of honeycomb even with each side edge.
5
Repeat step 3 for the fifth layer of honeycomb.

## Positioning Sling Assembly

3-9. Center the sling assembly over the honeycomb and skid board as shown in Figure 3-4.

## Positioning Load And Securing Sling Assembly

3-10. After centering the load on the sling assembly and honeycomb, cover the load with a plastic bag, shrink wrap or if that is not available, an A-22 cargo cover.  Secure and tie sling assembly as shown in Figure 3-5.

1
Fasten the long and short tiedown straps over the load using the friction adapters provided.
2
Tie each corner of the sling assembly around the load using the loops at the ends of the
lateral straps with 12-inch tubular nylon webbing forming a figure eight.  Secure with surgeon's knot and locking knot with overhand knots in the running end.
3
Bring the ends of the support web up, remove any twists, and tape them together 4 inches
below the lower D-rings using masking tape.

## Securing Sling Assembly To Skid Board

3-11. Tie the sling assembly to the skid board as shown in Figure 3-6.

1
Starting at the left side, take tiedown A and diagonally tie it an around the intersection of the
lower lateral strap and fourth web.  Use three half-hitch knots and overhand knot in the
running end.
2
Route tiedown B around the fifth support web and lower lateral strap intersection diagonally.
Pull the excess slack out, and tie it with a trucker's hitch knot and an overhand knot in the running end.  Cut excess webbing, leaving the end approximately 6 inches long.
3
Repeat step 1 for tiedown D, and secure it to the second intersection on the lower lateral
strap.
4
Repeat step 2 for tiedown C, and secure it to the first intersection on the lower lateral strap.
5
Repeat steps 1 through 4 for the other tiedowns (not shown).

## Installing Parachute

3-12. Install the 26-foot low cost parachute as shown in Figure 3-7.

1
Place the 26-foot low cost parachute on the load.  When the front and the rear have been
designated, the parachute sides should run parallel to front and rear.
2
Place both risers of the 26-foot low cost parachute in the bell of a medium clevis.  Put the D-
rings of the sling assembly on the bolt of the clevis, secure the clevis, and tape the nut.
3
Tie a length of type I, 14-inch cotton webbing to an upper lateral strap.  Pass the webbing
through the loop in the static line, under the static line stows, and over the parachute bag. Pass the webbing around a strap of the support web, and back up to the loop 18 inches from
the end of the static line.  Secure with a trucker's hitch.
4
Secure the static line with retainer bands as shown above.

## Marking Rigged Load

3-13. Mark the rigged load according to FM 4-20.103/MCRP 4-11.3C/TO 13C7-1-11 and as shown in Figure 3-8. Compute the rigged load data.

## Positioning A-22 Sling Assemblies

1
Place the first A-22 sling assembly toward the front-right corner of the honeycomb so the
front-right corner of the scruff pad is aligned with the front-right corner of the honeycomb.
Fully extend all lateral straps and support webbing.  Position sling assembly so the two short center tiedown straps (with the friction adapters) extend off the honeycomb stack toward the front and right.  Make sure the opposite (left and rear) support web D-rings extend beyond
the edge of the honeycomb.  Fold and place the lateral straps of the left and rear support webs (the webs that are on top of the honeycomb) and the long center tiedown straps, so
that they are on top of the support webs.
2
Place the second A-22 sling assembly toward the front-left corner of the honeycomb so the
front-left corner of the scruff pad is aligned with the front-left corner of the honeycomb.  Fully extend all lateral straps and support webbing.  Position sling assembly so the two short center tiedown straps (with the friction adapters) extend off the honeycomb stack toward the front and left.  Make sure the opposite (right and rear) support web D-rings extend beyond the edge of the honeycomb.  Fold and place the lateral straps of the right and rear support webs (the webs that are on top of the honeycomb) and the long center tiedown straps, so
that they are on top of the support webs.
3
Place the third A-22 sling assembly toward the rear-left corner of the honeycomb so the rearleft corner of the scruff pad is aligned with the rear-left corner of the honeycomb.  Fully
extend all lateral straps and support webbing.  Position sling assembly so the two short center tiedown straps (with the friction adapters) extend off the honeycomb stack toward the rear and left.  Make sure the opposite (right and front) support web D-rings extend beyond the edge of the honeycomb.  Fold and place the lateral straps of the right and front support webs (the webs that are on top of the honeycomb) and the long center tiedown straps, so
that they are on top of the support webs.
4
Place the fourth A-22 sling assembly toward the rear-right corner of the honeycomb so the
rear-right corner of the scruff pad is aligned with the rear-right corner of the honeycomb.
Fully extend all lateral straps and support webbing.  Position sling assembly so the two short
center tiedown straps (with the friction adapters) extend off the honeycomb stack toward the rear and right.  Make sure the opposite (left and front) support web D-rings extend beyond
the edge of the honeycomb.  Fold and place the lateral straps of the left and front support webs (the webs that are on top of the honeycomb) and the long center tiedown straps, so that they are on top of the support webs.
5
Use lengths of type VIII nylon webbing to tie the eight support web D-rings (that extend
beyond the edge of the honeycomb) to the second lateral strap.  Ensure that there is no slack between the support web D-ring and the second lateral strap.
6
Route the 12 lateral straps at the four midsections of the load through each opposing friction
adapter.  Do not apply tension at this time.

## Positioning A-22 Covers

5-11. Use four A-22 cargo bag covers when rigging this load.  Position the covers as shown in Figure 5-5.

1
Place the first cover to the front-right corner of the honeycomb so that the front-right corner of
the cover base is aligned with the right-front corner of the honeycomb.
2
Fully extend all cover flaps out flat.
3
Fold the right-rear and left-front flap excess even with the layer of honeycomb.
4
Place the second, third and fourth covers on the left-front, left-rear and right-rear corners,
similar to the first cover.  Fully extend all flaps and fold the excess so that they do not
overhang the honeycomb.

## Constructing Storage Box And Preparing Oversized Item Load

5-12. Construct a 96- by 96-inch plywood box using four sheets of 34- by 48- by 96-inch plywood as shown in Figure 5-6.  Prepare the drop items according to the load's sensitivity.


Note. All dimensions are in inches.

1
Using 6d nails at 1 foot intervals, nail a 2- by 4- by 48-inch piece of lumber onto each one of
the 48 inch edges of a 34- by 48- by 96-inch plywood sheet.
2
Repeat step 1 with an additional sheet of plywood.


3
Place plywood sheets prepared in steps 1 and 2 on edge and parallel approximately 8 feet
apart.
4
Position a 34- by 48- by 96-inch plywood sheet so that the 48-inch edge covers the exposed
edges of both the plywood sheets prepared in steps 1 and 2.  Secure by nailing 6d nails at 1
foot intervals through the plywood and into the studs.
5
Repeat step 4 on the opposite end with an additional sheet of plywood to form a 96- by 96-
inch box.
6
Center the 96- by 96-inch box on top of the prepositioned A-22 cargo bag covers.  Large,
bulky or heavy items may be placed on the center of the covers prior to positioning the box.

Note. Heavy items must be placed on the bottom.  The items must be placed so that the weight of the load is evenly distributed.  Place lighter items around and on top of the heavy items.

## Positioning Load And Closing Bag Covers

5-13. Center the load so that the weight of the load is evenly distributed.  Pad items with cellulose wadding or bubble wrap.  Place additional items into the box so that the box is completely cubed out.  Place additional honeycomb pieces inside the box as necessary to form a level top.  Close the bag covers as shown in Figure 5-7.

1
Fold the bad covers over the front and rear first, then the sides over the top.  Fold under any
excess in the flaps.
2
Use eight lengths of 12-inch tubular nylon webbing or type III nylon cord to lace the bag
covers closed in an hourglass configuration.  Pull the webbing tight and tie the running ends
in a surgeon's knot and bow knot.  Tape the excess and the knot.  Leave one running end slightly exposed to allow rapid derigging.

## Securing Tiedown Straps

5-14. Secure the tiedown straps as shown in Figure 5-8.

1
The long center tiedown straps will not be used.  Cut four lengths of type VIII nylon webbing
approximately 16 feet long.
2
Route each end of a single length of webbing through the friction adapters on opposite short
center tiedown straps.
3
Repeat step 2 for the other three lengths of type VIII nylon webbing.
4
Apply tension to the four lengths of type VIII nylon webbing.  Tie three alternating half-hitch
knots and a knot in the running end at the end of each length of type VIII nylon webbing at the buckle.  Cut the excess webbing.

## Securing Lateral Straps

5-15. Secure the lateral straps as shown in Figure 5-9.



Note. If the top lateral straps are on top of the load, make sure they are loosely tightened.



1
Lay the remaining portions of the sling assemblies over the load.  Route the corner lateral
straps through the friction adapters.
2
Tighten the center friction adapters so that the middle suspension web on each support web
is vertical.
3
Apply equal tension on the remaining lateral straps.  Fold the excess and tape or tie in place
(not shown).

## Securing Skid Board Ties

5-16. Secure the skid board ties as shown in Figure 5-10.

1
Starting at the front right side, take tiedown A and diagonally tie it around the intersection of
the lower lateral strap and fourth support web.  Use three alternating half hitch knots and an overhand knot in the running end.
2
Route tiedown B around the fifth support web and lower lateral strap intersection diagonally.
Pull the excess slack out, and tie it with a trucker's hitch knot and an overhand knot in the running end.
3
Repeat step 1 for tiedown D and secure it to the second intersection on the lower lateral
strap.
4
Repeat step 2 for tiedown C and secure it to the first intersection on the lower lateral strap.
5
Repeat steps 1 through 4 for the other seven sets of tiedowns.


## Installing Suspension Slings

5-17. Install suspension slings using support webs, type V platform clevises, and two 20-foot (2-loop), type XXVI nylon webbing slings as shown in Figure 5-11. Two 12-foot (2-loop), type XXVI nylon webbing slings girth hitched together  may also be used to form a single 24 foot sling as a substitute.


Note. Do not mix 12-foot and 20-foot slings on the same load.

1
Move the D-ring on the support webs down and tape in place.  Install a type V platform clevis
on each support web, at the former location of the D-rings.
2
Run a single type XXVI nylon suspension sling through the four type V platform clevises of
the front-right and rear-right support webs.
3
Repeat step 2 for the rear-left and front-left support webs.
4
Route a length of type III nylon cord through the eight type V platform clevises as shown
above.  Tie the ends together.  Make sure the tie has excess to allow suspension sling
movement.

## Installing Parachute

5-18. Install a reefed G-12 cargo parachute as shown in Figure 5-12.

1
Bring the four looped ends of the two suspension slings together and place the loops onto the
G-12 clevis.
2
Place a reefed G-12 cargo parachute on the load with the riser compartment up and the
bridle toward the front of the load.  Position the parachute on the front of the load.
3
Tie each corner of the parachute deployment bag to the A-22 sling assembly according to
procedures in paragraph 4-17, steps 1 and 2 (not shown).
4
Fold and tape the excess sling with masking tape (not shown).

## Marking Rigged Load

5-19. Mark the rigged load according to FM 4-20.103/MCRP 4-11.3C/TO 13C7-1-11 and as shown in Figure 5-13.  Compute the rigged load data.
