# Chapter 1 Rigging High Speed Low Level Aerial Delivery System (Hsllads) Container Loads

## Section I-Rigging The Container Description Of Load

1-1. The HSLLADS container (Figure 1-1) is an adjustable container made of an A-21 (nylon) cargo cover and other airdrop items. The assembled items are rigged to ensure that the container will withstand the shock of the parachute opening when airdropped at high speeds.


## Preparing Container

1-2. Dimensions of the load base in these procedures are typical. The size of the load base may change to fit other supply loads. Prepare the load base and HSLLADS container as shown in Figures 1-2 and 1-3.


When a container is rigged for delivery from Air Force aircraft, the rigged weight divided by the largest surface area (measured in square feet) must be a minimum of 35 pounds per square foot.

1
Drill 1/2-inch diameter holes 4 inches from each corner and 1 inch from the edge of a 3/4-
by 30- by 48-inch piece of plywood.
2
Center two additional 1/2-inch diameter holes on each 48 inch side of the skid 4 inches
from each other and 1 inch from the edge.
3

Thread a 12-foot length of 1/2-inch tubular nylon webbing through each pair of holes in the
skid. (Doubled, type III nylon cord may be used).
Note.  Denoted skid tiedown numbers are referred to in Figure 1-7.


1
Center a 30- by 48-inch piece of honeycomb on the skid.
2

Thread three 12- foot lengths of type X nylon webbing through the keepers on the A-21
cargo cover.


3
Place the cover, with the webbing down, on top of the honeycomb and skid.
4

Center another 3/4- by 30- by 48-inch piece of plywood and a 30- by 48-inch piece of
honeycomb on top of the cargo cover. This is the load base.

## Loading Container

1-3. Place the items to be airdropped on the honeycomb in the manner shown in Figure 1-4. Place the durable or heavy items on the bottom and the lighter or more fragile items on the middle or top layers. Use the cellulose wadding, felt or honeycomb to cushion the rigged items. Use honeycomb to level and square the load before closing the container.



Note. The rigged container must weigh at least 250 pounds but no more than 600 pounds.



1
Place the items to be airdropped on the load base.

Note. Only items that have been tested and approved for high-velocity or HSLLADS airdrop may be loaded in this container.


Square the load using the necessary honeycomb pieces.
2
Place a 3/4-inch piece of plywood cut to fit on each side of the load.
3
Tie the plywood in place with type III nylon cord.
4


## Constructing Container Straps

1-4.

 Construct two container straps as shown in Figure 1-5.


Note. 1. Sewing should be five to seven stitches per inch.
2. All dimensions given are in inches. 3. This drawing is not to scale.
1

Cut a 33-inch and a 2 1/4-inch length of type X nylon webbing.
2

Sear both ends of the webbing (not shown).
3

Sew a friction adapter and buffer in one end and a loop in the other end.
4

Use number 3 or 5 cord and sew the 6-inch, four-point WW stitch.

## Closing Container And Stowing Parachute

1-5. Close the container and secure the skid as shown in Figures 1-6 and 1-7. Attach and restrain a 22 foot cargo extraction parachute to the load as shown in Figures 1-8 and 1-9. If a 22-foot cargo extraction parachute is not available, use a 28-foot cargo extraction parachute.



1
Close the cargo cover, and fold under the excess material.

2
Place a 3/4-inch piece of plywood, cut to fit, on top of the load.
3
Fit the loop end of a container strap on the bolt of a cargo suspension clevis.

4
Pass the free end of a 12-foot, type X nylon webbing strap (attached to the A-21 container
cover) through the container strap's friction adapter.

5
Attach the second container strap to the other end of the 12-foot, type X nylon webbing
strap and then bolt the second cargo suspension clevis in the same manner as in steps 3
and 4.

6
Run the remaining type X nylon webbing straps around the container. Pass the ends of the
straps under and up through the cargo suspension clevises.

7
Place a D-ring on each end of the type X nylon webbing straps.

## Steps:



1.
Tie an end of the 12-foot length of 1/2-inch tubular nylon (positioned on the skid in Figure
1-1) to each clevis indicated below under the first tie column using three half-hitch knots and one overhand knot.


2.
Form a loop an appropriate distance from the end of each piece of 1/2-inch tubular nylon for
the second tie. Pass the free end through the clevis indicated below in the second tie column and back through the loop. Pull the 1/2-inch tubular nylon tight, and tie it with three half-hitch knots and one overhand knot.

Prepare and pack a 22- or 28-foot cargo extraction parachute according to TM 10-1670
277-23&P (28ft) or TM-1670-279-23&P (22-ft).
2
Place the adapter web of the cargo extraction parachute on a cargo suspension clevis.
3
Place four D-rings on the bolt of the cargo suspension clevis that has the adapter web
attached.
4

Tighten all straps. Fold any excess webbing, and tape it or tie it with 80-pound cotton
webbing.
when it is attached to the release system.


1
Be sure the parachute is installed so that the apex faces forward in the aircraft. Restrain
the parachute to the load with a tie of one turn of single, type I, 14-inch cotton webbing from each of the four cluster attaching loops to the straps on the container.

2
Use a 15-foot tiedown strap or a length of type XXVI, nylon webbing with two D-rings
attached as a load band around the rigged HSLLADS container at the estimated vertical
center of balance.

3
Place the two D-rings on the front of the load. Secure the tiedown strap with a D-ring and a
load binder.

## Chapter 2 Rigging Combat Rubber Raiding Craft Section I-Rigging Single Zodiac F470U Boat Description Of Load

2-1. The description of the load rigged in this section is given below.



-
Inflated zodiac F470U rubber raiding craft. This boat is rigged on a 75- by 144-inch combat expendable platform (CEP) with one G-12E cargo parachute. The weight of the boat is 250 pounds. When inflated, the boat is 75 inches wide, 185 inches long and 22 inches high. One or
two 35-horsepower outboard engines that weigh 136 pounds each power the boat shown or one 55 horsepower engine that weighs 215 pounds with a full fuel tank, six paddles weighing a total of 24 pounds and two sets of air pumps with hoses are parts of each boat's equipment.


Note. A 40-horsepower engine is the largest that may be used on this boat when the boat is equipped with the accordion floor. An engine as large as 65-horsepower may be used on this boat without the accordion floor.



-
Accompanying load. An accompanying load weighing at least 650 pounds but no more than
1,170 pounds must be dropped with the boat.

## Preparing The Platform

2-2. Build a new CEP, or recondition a used one, using the procedures shown in Figures 2-1 through 2-4 and as described below. This platform is used for all the loads in this chapter.

-
New platform. When no used CEP is available, build a new platform for this load as shown in
Figures 2-1 through 2-4. Salt-treated lumber is recommended for the platform frame.
-
Used platform. When a used CEP is available, inspect and recondition it as described below.
-
Inspecting for damaged or missing parts. Check the platform to see that all parts are present.
Inspect each part carefully for damage. When the following conditions exist, the platform is not suitable for use until it is repaired:

-
Any part is missing.
-
A stringer or spacer block is broken, cracked, split, or severely gouged.
-
A plywood panel is cracked or gouged through at least one ply for a width of 2 inches
or more.
-
A plywood panel is gouged for a length of 12 inches or more.
-
Inspecting parts, screws or nails. Check the entire platform for loose stringers, spacer blocks,
and plywood panels. Also, check for loose, missing, damaged, or protruding screws, bolts or nails. These defects may be corrected as follows:


-
Nail loose parts that are undamaged. Do not nail in original holes or in the grain line used before. Use screws when possible.
-
Replace loose, damaged, or missing nails, screws, and bolts. Reset or remove and
replace protruding nails, screws, and bolts.

# Rigging The Naval Special Warfare Rigid Inflatable Boat (Nsw Rib) For Low-Velocity Airdrop

## Description Of Load


4-1. The NSW RIB is a high-speed boat designed to be airdropped, and quickly recovered. It is rigged on a 21-foot Maritime Aerial Delivery System (MADS) platform. The platform separates from the boat during deployment, and drops with its own G-12 parachute. The platform is easily recoverable and reusable. The load requires four G-11 cargo parachutes. A water activated release system, with the M-2 release as a backup, ensures separation of the parachutes when the boat strikes the surface of the water. The maximum rigged load weight is 20,640 pounds, including an accompanying load that can vary according to the mission. The boat is 100 inches high, 108 inches wide and 432 inches long.

This load differs greatly from conventional airdrop loads. Strict adherence to these procedures is critical.

4-16. Prepare the restraint system as shown in Figure 4-28. Prepare the restraint system for test fire as shown in Figure 4-29. Test fire the system as shown in Figure 4-30.



1
Install a release caliper assembly on each of the boat restraint provisions (four on each side).
2
Make sure the long arm faces the stem of the boat.
3

Make sure the cotter pin on each arm faces outward.
4

Secure each caliper assembly in place with the pin provided.
5
With the ratchet handle facing outboard, pass a lashing through the link on the emergency aft
restraint bracket, and up through the long arm of the caliper release unit. Connect the lashing
at the ratchet.

6
From outboard, pass the free end of the second lashing through the large diameter pin of the
1/2-inch shackle fitted to the scissor release unit. Pass the free end upward and inboard through the short arm of the caliper release unit. Connect the lashing at the ratchet.
Note. Allow no twists in these lashings. Be sure that the protective sleeves on the lashings are positioned to protect them from metal contact. Do not tighten the lashings until all are installed.


7
With the ratchet handle facing outward, pass a lashing through the link between the first and
second row of flotation devices, and up through the long arm of the caliper release unit. Connect the lashing at the ratchet.
8
From outboard, pass the free end of another lashing through the large diameter pin of the
1/2-inch shackle fitted to the second scissor release unit. Pass the free end upward and
inboard through the short arm of the caliper release unit. Connect the lashing at the ratchet.
9
With the ratchet handle facing outward, pass a lashing through the link between the first and
second row of flotation devices, and up through the short arm of the caliper release units. Connect the lashing at the ratchet.

10
From outboard, pass the free end of another lashing through the large-diameter pin of the
1/2-inch shackle fitted to the first scissor release unit. Pass the free end upward and inboard through the long arm of the caliper release unit. Connect the lashing at the ratchet.

11
With the ratchet handle facing outward, pass a lashing through the rearmost link, and up
through the short arm of the caliper release unit. Connect the lashing at the ratchet.

12

From outboard, pass the free end of another lashing through the large-diameter pin of the
1/2-inch shackle fitted to the second scissor release unit. Pass the free end upward and
inboard through the long arm of the caliper release unit. Connect the lashing at the ratchet.

13
Repeat steps 1 through 12 for the other side of the boat.

Note. Starting at the stern, tighten the lashings simultaneously on the port and starboard sides. Tighten no more than hand tight. Proper tension is applied to a pair of lashings attached to each caliper release assembly when the pin can be withdrawn and re-inserted easily. Do not secure excess lashing until test-firing is completed.

1
Tie the running ends of the 1/2-inch tubular nylon webbing placed in Figure 4-7, step 4 to
each lashing, just above the shackle, making sure that 17 inches of nylon remains from knot to knot.
2
S-fold and tape the excess.
3


Cut twelve 24-inch lengths of type III nylon cord. Locate flotation device securing brackets 2,
4, and 6 (counting from the front of the platform). Tie two 2-inch loops of cord in each bracket, on either side of the flotation device retaining strap. Be sure the knots are on the inboard side of the brackets. Tie overhand knots in each running end, and trim the excess.
4
The lashing provision at the end of each of the 16 caliper release legs will have a length of
shock cord tied to a specific point on the platform with a trucker's hitch. Tie the knot so that it
can easily be retied between tests. Number the lashing points on each side from 1 through 8, beginning at the front of the platform. See the chart below for the specific points on the
platform to which each cord is tied.

damage. Be sure that the honeycomb does not interfere with the scissor release units (not shown).
6

Be sure that the push rod cable is disconnected from the halyard shackle before testing the
system (See Figure 4-6) (not shown).
7

Remove all eight safety pins from the caliper releases. Exert enough force on the pulley rope
to allow the push rod T-pin to be removed. Releasing the rope test fires the caliper releases. All caliper releases should release the lashings simultaneously (not shown).
8
Repeat the steps in Figures 4-28 and 4-29 to reset the system for the next test fire. Test fire
as explained in steps 1 through 3 above.
9
Repeat step 4 for the third test fire.

# Rigging The Advanced Rescue Craft (Arc) On A Combat Expendable Platform (Cep)

## Section I-Rigging The Gp 800 Arc Description Of Load

5-1. The GP 800 ARC shown in Figure 5-1 is rigged on a 48- by 87-inch combat expendable platform for low-velocity airdrop. This load can be rigged with or without a 20-man life raft and a rescue board, a rucksack, and an aid bag. The load requires one G-12E cargo parachute, a 15-foot cargo extraction parachute packed in a T-10 bag, and is only rigged with a hydraulic release.

## Building The Combat Expendable Platform

5-2. Build the 48- by 87-inch combat expendable platform as shown in Figure 5-2.

1
Lay out two 4- by 4- by 87-inch and two 2- by 6- by 87-inch longitudinal stringers.

2
Secure the lateral stringers to the longitudinal stringers with 8d nails. Do not nail within 2 inches of the ends of the 4- by 4- by 87-inch longitudinal stringers.


3
Lay two 2- by 6- by 44-inch and four 2- by 4- by 44-inch lateral stringers on top and across
the longitudinal stringers matching the measurements above.


4
Position the 3/4- by 48- by 87-inch plywood on top of the lateral stringers leaving a 2-inch
overhang on each side of the 4- by 4- by 87-inch longitudinal stringers.


5
Cut the corners of the platform at a 45-degree angle to include the corners of the 4- by 4- by
87-inch longitudinal stringers (not shown).
6
Turn the platform over and drill eight 3/4-inch holes for the carriage bolts. Ensure to drill again
with a large enough drill bit in order to counter sink the bolt heads, washers, and nuts (not shown).
7
Install the carriage bolts from bottom to top and trim the threaded ends at the nuts. File sharp
edges (not shown).
8
Drill a 2-inch hole centered on each end of the platform (not shown).


## Preparing The Platform

## Chapter 6 Wind Supported Aerial Delivery System (Wsads) Snow Goose Description Of Load



6-1. The Wind Supported Aerial Delivery System (WSADS) Snow Goose is a low-cost, reusable, fully autonomous, unmanned aerial vehicle (UAV) that can be used to carry out a variety of missions at otherwise inaccessible locations. It is quickly configurable for air or ground launch deployable missions.



Note. Before rigging the WSADS by this chapter, refer to the manufacturer's Pre-Flight Procedures to ensure all steps are adhered to. Mission requirements dictate the amount of fuel that is used, but each fuel cell will be full. Strict adherence to proper procedures is crucial to the survivability of this piece of equipment.

## Installing Air Launch Parachute

6-2. Install the Air Launch Parachute as described and shown in Figure 6-2.



It is a mandatory requirement that only qualified riggers who have successfully completed the Mist Mobility Integrated Systems Technology (MMIST) Air Parachute training course are certified to pack both the air launch and drogue parachutes. Packing both parachutes requires following precise, detailed procedures to ensure the successful and timely deployment of both parachutes. The Air Launch Parachute will be packed prior to rigging the WSADS and according to the manufacturer's rigging procedures.


1
Install the Air Launch Parachute Container to the Snow Goose top panel.
2
Secure both side flaps with the hardware provided.
3
Unfold the parachute container rear flap, outer side flaps and inner side flaps leaving the
front flap towards the front of the vehicle. The front flap has a channel guide for the locking pin bridle for easy identification.
Note. Ensure side flap with hook pile tape is installed on the right side.


4
Place the packed parachute in its recovery bag on top of the Snow Goose with the direction of flight arrow facing the front.
5
Open the recovery bag exposing the six lower riser shackle bolts (right side shown).

Note. The green-tagged risers should be on the right.


6
One at a time, disconnect each lower riser shackle from the recovery bag and immediately
connect it to the corresponding attachment point on the vehicle.
7
Insert shackle bolts from the outboard to inboard and tighten until screw pin clicks.

8
Once all six shackles are connected, ensure there are no twists in the lower risers (not
shown).

9
Pull each of the two Airborne Guidance Unit (AGU) steering lines to their full extension (called
mechanical zero).
Note: Right steering line should be 8 to 10 inches longer than the left steering line.


10

Feed the left steering line through the left guide ring at the top of the lower riser and connect
the left steering line end with the preset loop to the left parachute steering line extension using a rapide link connector.

11
Visually check to ensure that the steering line extension runs directly from the brake, down
the inner edge of the riser and then through the lower steering guide ring before the connection is made to the AGU steering line.

12
Visually check to ensure that the AGU steering lines run directly from the AGU to the
connection point, without twisting around the lower risers. Tape the steering lines with a
suitable length of masking tape.

13
Repeat steps 10 through 12 to connect the right AGU steering line to the right parachute
steering line extension.
14


Starting at the front, carefully stow the left steering line in the steering line channel on the
lower front left riser and S-fold any excess at the rear of the channel (not shown).


Note. Carefully stow all excess steering line in the upper rear riser steering line channel.


15 Repeat the above step carefully stowing the right steering line in the right steering line
channel.


Note. This step requires a second individual to remove the recovery bag.

16
Remove the recovery bag, and place the packed parachute immediately in front of the engine
intake, with the lines in front of the parachute.

17
Ensure the steering line or the brake setting does not get dislodged during the removal of the
recovery bag.

18
Place the left set of lower risers over the left edge of the vehicle on top of the side flaps and
repeat for the right set of lower risers.

19
Straighten the upper risers.
20 On the left side, pull the lower rear, middle, and front risers in the container area. S-fold the


riser within the container area keeping all three lower risers tight.


Note. Ensure neither the steering line, nor the brake setting gets dislodged during the S-folding process. This step also requires a second individual.



21
Repeat the above step on the right side (not shown).


22
Make sure that the left and right brake settings are still intact (not shown).


23
Cover the risers with the two inner container side flaps.


24
Roll the parachute over the S-folded risers leaving the lines at the rear of the vehicle.



25
Girth hitch the locking pin bridle short end to the deployment bag loop.

26
Close the flaps of the container starting with the front and rear followed by the sides (not
shown).

27

Before stowing the locking pin bridle, ensure bridle exits bag on the right side of the front flap
grommet. Stow the excess bridle outside the container with a retainer band located at the top of the channel guide.

28
Route a pull-up cord through each soft loop. Route the front pull-up cord through the
grommets in the following sequence: front, left, rear. Secure with short locking pin.


29
Repeat for rear pull-up cord using the long locking pin.


30
Remove the pull-up cords (not shown).


31
Ensure the corners of the front and rear flaps are neatly tucked under the side flaps.
32


Stow the drogue bridle in the bridle channel along the front of the container and along the
channel on the cowl. Secure with masking tape at intervals of 4 to 6 inches.

## Warning

Ensure the drogue bridle is routed over top of the steering line.

33


Connect the locking pin bridle to the drogue assembly with a small rapide link connector (not
shown).
34


Connect the hook pile tape on the drogue bag with the hook pile tape strip on the cowl.
Ensure the drogue bag is flush against the parachute.
35


S-fold excess locking pin bridle to keep off floor of the aircraft with a rubber retainer band.

## Installing Pyrotechnic Cutters

6-3. Install pyrotechnic cutters as shown in Figure 6-3.


## Warning

1
Install the pyrotechnic cutters between the Snow Goose drogue attachment point and the
medium rapide link connector on the drogue bridle ring (not shown).
2

Route a 14-inch piece of braided dacron (1575 pound breaking strength) through two
6 second (E-3) pyrotechnic cutters approximately 3 inches from the looped end.

3
Route looped end up through the drogue attachment ring and attach it to the rapide link.

Note. Ensure that only the cutter loop connects the drogue bridle to the Snow Goose drogue attachment point.


4

Route opposite end of the braided dacron up through rapide link and down through the drogue attachment ring.

5
Route over pyrotechnic cutters and attach to rapide link.
6
Close rapide link finger tight.
7
Once cutters are in place, ensure they are clear of the braided dacron cutter loop.
8

Connect two small rapide links to the sewn loop on the drogue bag, then connect a
pyrotechnic cutter to each rapide link.

9

Girth hitch two lengths of type I, 1/4-inch cotton webbing to the sewn loop on the drogue bag.
Tie one length to the drogue attachment ring, and the other to the front frame (this reduces lateral and vertical motion of the drogue bag and prevents early activation of the pyrotechnic cutters).

10
Tie a length of ticket 5, 8/7 cotton thread across the pyrotechnic cutters to secure the cutters
to the drogue attachment ring.

## Recovery Dispatch Pin Placement

6-4. Install recovery dispatch pin as shown in Figure 6-4.

## Warning


1
Ensure that both the Master Panel-Arming Switch and the Engine Start Enable Switch are
both in the off position.

## Warning

Failure to replace the recovery dispatch pin will prevent the AGU from starting the engine after it leaves the aircraft resulting in the possible loss of the Snow Goose and a failed mission.

2
Remove the recovery dispatch pin and immediately insert the drogue bag dispatch pin line.
3
Push the dispatch pin line through the dispatch switch cover as far as possible to prevent
accidental removal.

## Securing Landing Gear

6-5. Secure landing gear as shown in Figure 6-5.


1
Depress the leg release pin and insert two leg support lanyards over the top of the pin and under the guard.

Ensure only the leg release pin and not the guard holds each lanyard.



## Warning

The landing gear support lanyards must pass underneath the parachute risers when securing the landing legs. Passing a lanyard over the top of the riser will result in damage to the Snow Goose, including the landing gear.

2

Raise the left side of the vehicle skid and pass the other side of the left landing gear support
lanyard underneath the parachute riser.
3

Pass the unfinished end of the 53-inch braided dacron through the eyebolt and secure with
three half hitches and a knot in the running end.


Note. The landing gear support lanyard will come from the manufacturer with one end finger trapped and 53 inches long.

4
Repeat steps 2 and 3 for the right side landing gear support lanyard (not shown).

## Installing Propeller Brake

6-6. Install propeller brake as shown in Figure 6-6.



1
Install left propeller brake by passing the elastic lanyard end through the eyebolt on the rear
end of the skid. Secure the free end of the brake release lanyard to the vehicles left skid center eyebolt with three half hitches and a knot in the running end.
2
Install the propeller brake 4 to 6 inches from the tip of the propeller. Route a suitable length of
type III nylon cord through the left skid rear end eyebolt and tie it tight to the eyebolt using
half hitches and a knot in the running end.

Note. Do not overcome the tension of the elastic lanyard with type III nylon cord.

3

Repeat steps 1 and 2 for the right side brake release making sure the propeller blades are evenly positioned and secured.


## Installing Deflector Lanyards

6-7. Install deflector lanyards as shown in Figure 6-7.

1
Secure the end of a riser deflector lanyard to the left skid front padeye or eyebolt with three
alternating half hitches and a knot in the running end.
2
Route the deflector lanyard behind the drogue tube, through the 24 second (E-3) pyrotechnic
cutter, between the drogue attachment strap, and behind the locking pin bridle.

3
Attach the opposite end of the deflector lanyard to the right skid front padeye or eyebolt and
secure with three alternating half hitches with a knot in the running end.

4
Attach the cutter to a small rapide link, and safety with ticket 5, 8/7 cotton thread to the L-link
above the drogue ring. Shown above and on the next page.

5
Route the riser deflector unfinished end through the right deflector overhand loop and secure
through the eyebolt using three alternating half hitches with a knot in the running end (not
shown).
Note. Tension of the deflector lanyards must not overcome tension supplied by the leg support lanyards.



The deflector must be routed under the drogue tube and the locking pin bridle.


6
Secure all lanyard loose ends with suitable lengths of masking tape (not shown).

## Equipment Required

6-8. Use the equipment listed below in Table 6-1 to rig this load.



Note. Along with the equipment list, it is recommended that an air drop kit with the following contents be added: (Braided Dacron lanyards, pyrotechnic cutters, propeller brakes, masking tape, cotton wadding and ticket 5).
