RIGGING LOW-COST AERIAL DELIVERY SYSTEM
Chapter 12
General Information and Procedures
LCADS COMPONENTS
12-1. LCADS is a modified, lightweight A-22 system with no scuff pad, cover,
suspension webs, or friction adapters on the lateral bands. LCADS is used for
high-volume delivery of non-fragile items where airdrop equipment is not
recoverable. The LCADS shown in Figure 12-1, employs a lower cost version of the
A-22 sling assembly. The low cost sling assembly uses a more readily available
and more economical material and eliminates much of the hardware thus reducing
the costs.
LCADS SKID BOARD
12-2. Like the standard A-22 container, the sling assembly is secured to a 3/4 or
1- by 48- by 48-inch piece plywood (Grade AC) skid board with 1/2- inch tubular
nylon webbing. Honeycomb is positioned between the container and the skid board
for impact cushioning.

2 September 2005
12-1
FM 4-20.103/MCRP 4-11.3C/TO 13C7-1-11
LCADS CONTAINER LIMITATIONS
12-3. The LCADS container has a weight restriction of 501 to 2,200 pounds.
INSPECTING LOAD
12-4. The LCADS 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
12-5. There are three types of parachutes used for LCADS loads, depending on
whether the load is being dropped for low-velocity or high-velocity airdrop.
a. LOW-VELOCITY DROPS. The G-12E cargo parachute is the primary
parachute for low-velocity airdrops. It is rated for 501 to 2,200 pounds of
suspended weight. A 68-inch pilot parachute is installed on the G-12E cargo
parachute to deploy it. Other parachutes may be used to deploy the G-12E
cargo parachute; however, the specific manual must give the procuderes.
b. HIGH-VELOCITY PARACHUTE.
(1) Primary Parachute. The 26-foot low-cost parachute performs
identical to the standard 26-foot high-velocity parachute except the low
cost parachute is designated for one-time use. The low cost parachute
is pre-packed and ready to attach to the load.
(2) Alternate Parachute. The 26-foot high-velocity cargo parachute
is rated for 501 to 2,200 pounds of suspended weight. TM 10-1670-279-
23&P/TO 13C5-27-2/NAVAIR 13-1-28 covers the inspection and packing
of the parachute.

Rigging Typical Low-Cost Aerial Delivery System Loads
SECTION I - RIGGING LCADS FOR LOW-VELOCITY AIRDROP
SYSTEM DESCRIPTION
13-1. The LCADS is rigged as a typical A-22 low-velocity load. Typical loads
include rations, repair parts, water, and/or other small items. Items may be
dropped in their original configuration or repackaged for greater protection.
The LCADS container loads must weigh at least 501 pounds but not exceed
2,200 pounds excluding the parachute. The load is rigged with a G-12E cargo
parachute.
PREPARING ITEMS AND SKID BOARD
13-2. Prepare the skid board using Figure 9-1. Prepare the items to be dropped
according to load's sensitivity. Items must be well padded to prevent damage
during airdrop.
PREPARING AND PLACING HONEYCOMB
13-3. Prepare and place the honeycomb as shown in Figure 9-2.

POSITIONING LOAD AND SECURING SLING ASSEMBLY
13-5. Center and secure the load on the sling assembly and honeycomb. If a
cover is available, cover the load with a plastic bag, shrink wrap or an A-22
cargo cover. A cover is not required. Secure and tie the sling assembly as
shown in Figure 13-2.

1 Secure the load together with 1/2-inch tubular nylon around each layer.
2 Cut and position a 36- by 44- and 8- by 44-inch piece of honeycomb on top of the load.
Tape the pieces together and around the outside edges. Position the honeycomb cen
tered on top of the load.
NOTE: When 55-gallon drums are used, cut and position a 44- by 44- by 1-inch piece
of plywood on top of the four 55-gallon drums.
3 Cover the load with shrink wrap, plastic, or an A-22 cover (Not shown or required).

5 Tie each corner of the sling assembly with 1/2-inch tubular nylon webbing; route the
webbing up through the bottom webbing loop, across the ties, up through the next loops,
and repeat until the top loops are reached. Secure the ties together on the top corners
with a surgeon’s knot and locking knot. Secure the excess webbing to the loop of the
opposite corner with three alternating half hitches with a knot in the running end.
NOTE: On a load where the top lateral straps are above the top of the item, secure the
loops together as closely as possible with the tie on top.
6 Bring the ends of the support web up, remove any twists, and tape them together 4
inches below the D-rings using 2-inch masking tape (not shown).

Chapter 14
Fabricating Air Force Airdrop Equipment
SECTION I - AIR FORCE UNILATERAL TRAINING
DESCRIPTION OF LOAD
14-1. This chapter shows how to make a standard airdrop training bundle
(SATB) for use in unilateral training by the Air Force. The SATB is used to
simulate personnel, heavy equipment, and container airdrops from a C-130
aircraft. It consists of a sandbag filled with 13 1/2 pounds of sand or gravel and
a locally made canvas bag. A 15-foot cargo extraction parachute deployment
bag may be substituted for the canvas bag.
PREPARING SANDBAG
14-2. Fill a sandbag with 13 1/2 pounds of sand or gravel. Wrap the excess
portion of the bag around the filled portion to make a compact unit. Secure the
bag as shown in Figure 14-1.

2
1 Pass a length of type I, 1/4-inch cotton webbing around two sides of the bag. Pull the
webbing tight and tie the ends of the webbing together with a surgeon’s knot and a
locking knot.
2 Pass a length of type I, 1/4-inch cotton webbing around the opposite sides of the bag.
Pull the webbing tight and tie the ends of the webbing together with a surgeon’s knot
and a locking knot.

NOTE: The canvas (duck cloth) may be painted orange or yellow for easy identifica
tion.
1 Make a main body strap from a 56-inch length of type VIII nylon webbing. Mark the
webbing at points 25 inches from each end. Form a pendulum line attatching loop by
rolling the edges between the marks and sewing the rolls in place with a lockstitch.
2 Lay out an 11- by 36-inch piece of canvas and mark it as shown.
3 Sew two V-rings to the canvas with a box stitch or a single X-box stitch as shown.
4 Sew the edges of the main body strap to the canvas as shown.

Fold the canvas in half lengthwise with the main body strap on the inside.
6 Make tie tabs by cutting four 4-inch lengths of type IV, 1-inch nylon webbing. Fold the
webbing in half lengthwise and mark each piece 1 inch from the folded end.
7
Start sewing the two long outside seams with a double row of locking stitches. Sew the
tie tabs to the canvas by inserting the folded end of the tie tabs inward on the 10-inch
marks (step 2).

1 Mark a location at 6 1/2 inches and another at 8 inches from the end of an 85-inch
length of type IV coreless nylon cord.
2 Insert a splicing tool into the cord at the 8-inch mark. Slide the cord onto the tool and
push the end of the tool out at the 6 1/2-inch mark.

the canvas bag used to enclose the sandbag, prepare the SATB as described
below.
a. Place the filled sandbag in the deployment bag and tie the deployment
bag closed.
b. Safety a 68-inch pilot parachute to the deployment bag as shown in
Figure 14-5.
