## Preface Scope

The purpose of this manual is to provide the latest approved procedures for rigging Dual Row Airdrop System (DRAS) platforms. This manual is written for use by the parachute rigger. The procedures contained in this manual are typical and serve as the standard from which all DRAS platform rigging is derived. Due to the uniqueness of some equipment and items, the procedures in a specific rigging chapter may be different from those in chapters 1 and 2. When procedures are different, those in the specific chapter will be followed. When an item of equipment is specified to be used for which its minimum or maximum capacity is exceeded, a notice of exception will be printed at the beginning of each paragraph in each rigging chapter where the exception is authorized.
Chapters 1 and 2 contain specific limitations and general information about the rigging of DRAS airdrop platform loads for low-velocity airdrop from the C-17 (Globemaster) aircraft, shows and tells how to prepare, attach, and safety tie some of the components and systems used in the specific rigging chapters of the TM 4-48.05 (FM 4-20.105 VOL I & II)/TO 13C7-1-51.

## Chapter 1 Airdrop Information Responsibilities

1-1. US Air Force personnel are responsible for loading rigged Dual Row Airdrop System (DRAS)
platform loads into the C-17 (Globemaster) aircraft and installing and operating the airdrop system.

## Safety Precautions

1-2. Safety precautions **MUST** be closely followed when airdrop platform loads are rigged.  Failure to
follow the precautions could result in serious injury to personnel or damage to the drop item or aircraft.
The following safety precautions shall be taken by the rigger:
- Make sure that when lifting heavy items, the lifting device has a rated lifting capacity that exceeds
the weight of the item to be lifted.
- Make sure that items being lifted are secured to the lifting device. - Avoid working under equipment suspended above a DRAS platform unless absolutely necessary.
- Cover all wet cell batteries in service with plastic or nonflammable material. - Check fuel tanks to ensure that they do not exceed the fuel level of the specific rigging chapter.
Check fuel tanks of small engines to make sure they are drained.  Check fuel cans to make sure
they are performance-oriented packaging approved.  When stowing fuel cans, use cellulose
wadding or other suitable material to prevent metal-to-metal contact.
- Package, mark, and label hazardous materials according to AFMAN 24-204(I)/TM 38-250.
Only ammunition listed in TM 4-48.16(FM 4-20.153)/MCRP 4- 11.3B/TO 13C7-18-41 may be airdropped.

## Type And Method Of Airdrop

1-3. As used in this manual, DRAS allows platforms to be loaded side-by-side inside C-17 aircraft.
DRAS airdrop is designed to supplement the usual surface methods of delivering supplies and equipment
to forces in the field.
- **Type of Airdrop.**  Currently the only type of airdrop used to deliver platform loads is lowvelocity airdrop.  DRAS low-velocity airdrop delivers platform loads from C-17 aircraft.  The G- 11D cargo parachutes are used to slow the descent of the loads to ensure minimum landing shock. The number of cargo parachutes can vary as shown in Table 1-1.  Loads with different quantities of the same type parachute may be airdropped from the same aircraft or element provided the following conditions are met:

Airdrop altitude for the aircraft or element will be determined by the type and number of
parachutes on the load requiring the highest airdrop altitude.

Aircraft or elements with lower airdrop altitudes will drop before aircraft or elements with
higher airdrop altitudes.

The transported force accepts strike report responsibility for loads other than the first platform to exit the aircraft or element lead for formation airdrops.

| Minimum Drop Altitude (Feet AGL)    | Parachutes    |
|-------------------------------------|---------------|
| 1,200                               | 2 to 4 G-11D  |

Drop altitudes reflect MINIMUM drop altitudes.

- **Method of Airdrop.**  The gravity method is used for DRAS platform loads delivered by lowvelocity airdrop.  The aircraft flies at an incline of approximately 4 degrees, the locks holding the platforms are removed, and the loads roll out of the aircraft by gravitational pull.

## Commonly Used Items

1-4. Items commonly used for rigging DRAS platform loads are described in this section.  Each rigging chapter in TM 4-48.05 (FM 4-20.105 VOL I & II)-1/TO 13C7 -1-51 contains one or more tables of equipment required.  These tables list the NSN, item, and quantity of each item needed to prepare and rig the load covered in that chapter.  Standard DRAS hardware items are shown in Figure 1-1.  Standard DRAS straps and canvas items are shown in Figure 1-2.  Some textile, wood, and miscellaneous items are described below.

- **Textile Items.**  The most common textile items and their uses are as follows:


Type III nylon cord is used to make safety ties and to hold items in place.  It has a tensile
strength of 550 pounds.

1/2-inch tubular nylon webbing is used to secure items during airdrop.  It has a tensile
strength of 1,000 pounds.

5/8-inch or 9/16-inch tubular nylon webbing may be used for parachute clustering ties in
place of 1/2-inch tubular nylon webbing.  Five eighths inch tubular nylon webbing has a tensile
strength of 2,250 pounds and 9/16-inch tubular nylon webbing has a tensile strength of 1,500
pounds.

3/4-inch tubular nylon webbing is used to secure items during airdrop.  It has a tensile
strength of 2,300 pounds.

1-inch tubular nylon webbing is used to secure the guillotine knife.  It has a tensile
strength of 4,000 pounds.

Type VIII nylon webbing is used for parachute restraint and to safety tie the rectangular
outrigger foot assembly.  It has a tensile strength of 4,000 pounds.

Type I 1/4-inch cotton webbing is used to make safety ties and to hold items in place.  It
has a tensile strength of 80 pounds.
- **Wood Items.**  Wood items used when DRAS loads are rigged for specific airdrop are made
locally.  Details for building these wood items are in the rigging chapter.
Note.  Plywood will be grade AC or AD.

- **Miscellaneous Items.**  Miscellaneous items that may be used when a platform load is rigged are
discussed below.  The proper use of these items will be covered in detail in the specific rigging chapter for the load.

Adhesive tape (masking tape), 2 inches wide, is used to secure folds of excess webbing.
It is also used to protect honeycomb from being cut by type III nylon cord and to hold padding in place.  It can be used for other tasks also.

Type IV, cloth-backed adhesive tape, 2 inches wide, is used to protect honeycomb from
being cut by type III nylon cord and to hold padding in place.  It can be used for other tasks also.

Cellulose wadding and felt sheets have many uses.  They may be used to pad fragile items,
to prevent sharp edges from cutting, and to protect slings during airdrop.

Energy-dissipating pads (honeycomb) are used to absorb the landing shock.  Honeycomb
is also used to level, pad, and fill empty spaces.
1
The large clevis is used to group bridles and attach riser extensions to the G-11D cargo
parachute.  The clevis is used in other places, as indicated in the specific rigging chapter.
2
The medium clevis is used as a guide for the suspension slings on the attitude control
system.  Other uses are given in the specific rigging chapter.
3
The 10,000-pound load binder is used to hook two D-rings together or to hook a D-ring to a platform tie-down clevis on the airdrop platform.
4
The heavy-duty D-ring is used with a 15-foot tie-down strap.
5
The platform clevis is attached to the side rails of the DRAS platform in order to secure the
load.
6
The 3 3/4-inch, two-point link assembly is used to join suspension slings and to attach the
deployment line to the deployment parachute adapter web.
7
The guillotine-type knife is used on the parachute release strap to cut the parachute
restraint straps.  The guillotine knife is also used to cut the outrigger vertical restraint ties.
8
The attitude control system (ACS) is a locally fabricated item used as a spreader bar on all
loads.  The ACS also helps to control the attitude of the platform during extraction of the load.  Each load requires two ACSs.  The fabrication procedures are shown in Figure 2-40.
1
The CGU-1/B aircraft cargo tie-down is used to safety the outriggers in the vertical position
and on the ACS.  The strap is removed from the outriggers prior to airdrop.
2
The 15-foot dacron tie-down strap is used to lash a DRAS load to the platform.  Other uses of this strap are covered in the specific rigging chapter.
3
The large clevis cover is used on the large clevis when the clevis is used to join the risers
of a cargo parachute to a riser extension.

## Inspection Of Items

1-5. Canvas, metal, webbing, and wood items are inspected according to TM 10-1670-296-20&P/TO
13C7-49-2.

## Maximum Rigged Weight

1-6. The weight cited in the rigged load data for each specific load is typical for the load as shown.  Some amount of overweight is allowed as long as load dimensions and rigging procedures are not changed.  The maximum rigged weight for a DRAS platform is 14,500 pounds.

Note. When a maximum allowable rigged weight is specified in the rigged load data, this weight is the absolute maximum and will not be exceeded.

## Accompanying Loads

1-7. Accompanying loads are items of supplies and equipment that may be added to a primary load.  Each airdrop chapter states whether an accompanying load is authorized.

## Stowing Accompanying Load

1-8. Each specific rigging chapter contains the weight limitations, placement, and any additional restrictions on accompanying loads.

1. Accompanying loads may vary, however, accompanying load locations will not. 2. Only ammunition listed in TM 4-48.16(FM 4-20.153)/MCRP 4- 11.3B/TO 13C7-18-41 may be rigged for airdrop. 3. Hazardous materials must be packaged, marked, and labeled as required by AFMAN 24-204(I)/TM 38-250.
4. At least two layers of honeycomb must be placed under all ammunition rigged for airdrop unless the specific rigging chapter states differently.

## Preparing Drop Items

1-9. Some items need to be prepared for rigging.  This preparation can include removing, reinforcing, stowing, and securing components.  Detailed preparation instructions will be included in the specific rigging chapter.

## Covering Load

1-10. Covers may be needed to protect the load and keep the suspension slings from fouling.  To keep the load from being damaged by falling hardware such as parachute releases, it may be necessary to cover portions of the load with honeycomb or cloth protectors.  If a cover is needed, the specific rigging chapter will include this information and the procedures for its installation.

## Center Of Balance

1-11. The center of balance (CB) of a DRAS airdrop platform load is based on the total rigged weight and is given in the rigging chapter for a particular item.  The CB must fall between 85 and 99 inches from the front of the platform.  The CB of each load must be verified.  Methods for computing the CB are in the Appendix of I.

## Items And Loads Dropped In Cold Climates

1-12. Some items to be dropped may have been modified for use in cold climates by the installation of extra equipment.  Special rigging procedures may be needed when the drop item has been so modified. When loads are to be dropped in cold climates, all excess webbing of suspension slings and tie-down straps must be folded and tied with type I, 1/4-inch cotton webbing.

## Knots

1-13. Some of the knots used for rigging platform loads are shown in Figure 1-3.



Make an overhand knot in one end.

## Chapter 2 Rigging And Procedural Information Section I - Dual Row Airdrop Platform General Information

2-1. The DRAS platform, as shown in Figure 2-1, serves as the base on which supplies and equipment are restrained.  This platform also supports the load during the extraction, parachute deployment, suspension, and recovery phases.  The DRAS platform is used for low-velocity airdrop.  The DRAS platform is 18 feet long.  The assembled platform is 88 inches wide.  A detailed description of this platform is in TM 10-1670- 268-20&P/TO 13C7-52-22.  The DRAS platform spreads the shock of ground impact.  The outrigger assembly helps to prevent the platform from rolling over.  Limitations for the DRAS platform are listed in Table 2-1.

## Platform Limitations

2-2. The C-17 (Globemaster) aircraft is specifically designed to deliver supplies and equipment using the DRAS during airborne operations.  Platform loads are generally restricted to a height of 118 inches.
Platform loads are generally restricted to a weight of 14,500 pounds.  For multiple platforms, up to 116,000 pounds of airdrop load may be airdropped.  The aircraft has a capability of eight DRAS platforms, six on the floor and two on the ramp.

## Platform Preparation

2-3. The DRAS platform is inspected, or assembled and inspected, as outlined in TM 10-1670-268-
20&P/TO 13C7-52-22.

## Preparing The Platform

2-4. The platform must be prepared by attaching outrigger link assemblies and the outrigger platform support weldments according to TM 10-1670-268-20&P/TO 13C7-52-22.  Install the clevises according to the specific rigging chapter.  Figure 2-2 gives an example of how to bolt the clevises to the bushings in the platform side rails and how to number them.


Steps:

1. Install the outrigger link assembly and the outrigger platform support weldment according
to TM 10-1670-268-20&P/ TO 13C7-52-22.
2. Bolt the clevises to the bushings in the platform rails as shown in the specific rigging
chapter.
3. Starting at the front of the platform, number the clevises bolted to the right side beginning
with 1 and those bolted to the left side beginning with 1A.
4. Starting at the front of the platform, number the two tie-down rings in the panels A and B
from right to left.  Starting with the first panel, number the tie-down rings beginning with 1
from front to rear.

Notes.
1.  The single clevis is sometimes installed in an inverted manner if the specific rigging chapter calls for it. 2.  One clevis is sometimes installed on another inverted clevis.  This is called a double clevis. 3.  Two clevises attached to an inverted clevis are called a triple clevis.  The two clevises will be numbered as two separate clevises. Do not number the inverted clevis.



## Building Honeycomb Stacks

2-5. Honeycomb stacks must be prepared according to the specific rigging chapter.  Honeycomb is used to absorb the landing shock.  Figure 2-3 shows a typical honeycomb stack.



Note.  When honeycomb stacks are longer than 96 inches or wider than 36 inches, alternate the layers to build a solid, cohesive stack.

3
Lumber.
4
Plywood.
5
Cutouts or notches.
6
Layers of honeycomb.
Note. Glue the layers of the stack together.



## Placing Honeycomb Stacks

2-6. Honeycomb stacks must be set on the platform according to instructions in the specific rigging chapter.  Figure 2-4 shows a typical placement of honeycomb stacks on a DRAS platform.

1
Place the honeycomb stacks on the platform according to instructions in the specific rigging chapter.
Note.  Do not glue the stacks to the platform.

2
Number the stacks from front to rear in a numerical sequence with 1 at the front of the
platform.

## Drive-Off Aid Airdrop

2-7. The drive-off aid may be used with the HMMWV truck.  The drive-off aid, showing the front platform attachment (Figure 2-5), consists of a fabric track constructed of type X webbing sewn into a ladder-type configuration.  The system is placed on two of the identified vehicle's tires and attached to the DRAS platform with type V webbing or 1-inch tubular nylon webbing.  There are two tracks to each system.  Each track is 30 feet long and 22 inches wide and weighs 21 pounds.  When powered up, the vehicle (with tie-down assemblies removed), will progressively wrap the webbed ladder around the two tires (using the platform for leverage) and pull itself clear of the honeycomb and platform.

FRONT PLATFORM ATTACHMENT

Note. If the vehicle is to be driven off the front of the platform, tie a length of type V nylon webbing or 1-inch tubular nylon webbing from the first bushing through the end loop of the drive-off aid, and through the nearest tie-down ring.  When attaching the drive-off aid to the platform using type V or
1-inch tubular webbing, tie the free ends with a ring bend knot as shown in Figure 1-3.  Tie the drive-off aid to tie-down rings or platform bushings with type I, 1/4-inch cotton webbing.

Note.  Wrap the drive-off aid around the wheel of the vehicle on each side as shown.  Tie the end loop of each drive-off aid to the nearest cross piece with a doubled length of type I, 1/4-inch cotton webbing.  Wrap the drive-off aid around the wheel until the webbing lays flat on the platform, but is not under tension.  Tie the drive-off aid to adjacent tie-down rings or platform bushings on each side with type I, 1/4-inch cotton webbing.



## Section Ii - Suspension Slings Cargo Slings

    2-8. Cargo slings (Figure 2-6) are used as suspension slings on DRAS loads.  These slings suspend the
    load under the cargo parachutes during descent.  Suspension slings connect the cargo parachute to the load
    using a parachute release assembly.  Cargo slings may also be used as deployment lines and to extend the
    risers of cargo parachutes.  Cargo slings are also used in the fabrication of the ACS.


1
Each sling is made with continuous loops.  The loops are 1 3/4-inch-wide, type XXVI nylon webbing. They are held together with keepers of 1-inch, nylon reinforced tape.  Each sling has a sliding webbing keeper and a cotton or nylon buffer at each end.

Notes.

1.  The keeper at each end of the sling must be drawn snugly against the object on which the sling is fitted. 2.  Suspension slings on DRAS loads will have the nylon buffers removed to fit on the lower suspension links of the M-1 parachute release assembly.



## Requirements

2-9. Loads rigged for use on the DRAS platform require 4-loop, type XXVI nylon suspension slings.
The type and length of cargo slings authorized for use on a DRAS load are listed in Table 2-2.

## Section Iii - Lashings Use

2-11. The drop item and the accompanying load are lashed to the platform to prevent damage to the load or to the aircraft during airdrop.  The accompanying load is lashed to the platform to withstand the same force as the drop item.

## Components And Strengths

2-12. The components of the lashings used on DRAS loads are shown in Figure 2-8.  The maximum strengths of the various forms of lashings are given in Figure 2-9.

1
15-foot dacron tie-down strap.
2
Heavy-duty D-ring.
3
10,000-pound-capacity load binder.

1
Single line configuration.  A dacron lashing routed in a single line configuration has a
maximum strength of 6000 pounds when attached to a DRAS platform side rail and a tiedown clevis.  It has a maximum strength of 4,000 pounds when attached to a panel tiedown ring.
2
Double line (floating binder) configuration.  A dacron lashing routed in a double line
configuration has a maximum strength of 10,000 pounds when attached to a DRAS platform side rail and a tie-down clevis.  It has a maximum strength of 4,000 pounds when attached to a panel tie-down ring.

## Fitting D-Rings

2-13. Fit a D-ring to the end of each tie-down strap as shown in Figure 2-10.

*Suspended weight in pounds is the total rigged weight less the weight of the cargo parachutes.

## Types

2-18. The G-11D cargo parachute is used when loads are rigged for DRAS.  The parachute has a 100-footdiameter canopy.  It has 120 suspension lines (35-foot, type III nylon cord).  The parachute has four 2- second cutters and four 12-foot reusable reefing lines.  When packed, the assembly weighs 250 pounds.

## Riser Extension Requirements

2-19. Cargo parachutes are used in a cluster.  When parachutes are used in a cluster, the risers of each parachute are lengthened so the canopies remain almost vertical as they descend to increase the effectiveness of each canopy.  The length of a riser extension and the number of stows used in stowing the extensions are given in Table 2-4.

2 8

20-foot (2-loop) 60-foot (3-loop)

20 60


Note.  All riser extensions must be continuous type XXVI nylon slings and each must be the same length.



## Riser Extensions

2-20. The risers of a cluster of G-11D cargo parachutes used on DRAS loads must be extended
(lengthened).  The length of the extension needed for the cluster is given in Table 2-4.
- **Forming extensions**.  Only continuous riser extensions may be used.
- **Bolting extensions to risers**.  Bolt the riser extension to the risers of a cargo parachute as shown
in Figure 2-15.
1
Slip a clevis cover on one end of a riser extension.
2
Fit the sling on the bolt of the clevis running through the parachute risers.
The nuts must be tight enough to keep them from loosening during transport and airdrop.

3
Slide the clevis cover up over the bolt of the clevis, and tie the cover in place with a length
of type I, 1/4-inch cotton webbing.  Pass the tie through the grommets of the cover.
4
Tie the clevis to the left bottom bag carrying handle with one double length of type I, 1/4-
inch cotton webbing.

## Stowing Riser Extensions

the folded end through the left carrying handle.  Run the free ends of the webbing through this loop, and pull the webbing taut.
2
Run the webbing across the parachute, passing it through the riser extension retaining
loops (end tabs).
Note.  Do not pull the webbing tight across the parachute.
3
Tie the webbing to the right top carrying handle with three alternating half hitches and an
overhand knot in each free running end.
4
Start at the end of the riser extension fitted to the clevis and S-fold the riser extension into
the riser extension compartment.
5
Leave about 3 feet of the free end of the extension outside the riser end of the
compartment.
Do not girth hitch the type I, 1/4-inch cotton webbing ties to the riser extension securing line.

6
Tie each stow to the riser extension securing line with ties of one turn double type I, 1/4-
inch cotton webbing.

## Stowing Cargo Parachutes

2-22. When referring to cargo parachutes, stowing consists of three steps.  First, place the cargo parachutes on the load or on a parachute stowage platform.  Second, cluster the parachutes by tying their deployment bags handles together.  Third, group the bridles on a large clevis.  Stow the parachutes as shown in Figures 2-19 through 2-22.

Note.  Nylon and cotton bags may be mixed on the same load.

## Using Deployment Lines

    2-23. The deployment line for DRAS loads is a 3-foot (4-loop), type XXVI nylon webbing sling.  One end
    of the deployment line is fitted on a 3 3/4-inch two-point link attached to the adapter web of the
    deployment parachute.  The other end of the line is fitted to the bolt of the large clevis grouping the bridles
    of a cluster of parachutes.

## Section V - Deployment Line And Parachute Use

2-25. A deployment parachute is used on every DRAS load to deploy the G-11D cargo parachutes as the load leaves the aircraft.  The deployment parachute is a 28-foot extraction parachute packed in a deployment bag and rigged with a release-away static line assembly.

## Inspecting And Maintaining

2-26. Deployment parachutes are inspected, maintained, and packed as outlined in TM 10-1670-277-
23&P/TO 13C5-28-2.  See the specific TM for more information on inspecting, maintaining, and packing these parachutes.  The 28-foot extraction parachute deployment bag modification procedures are located in TM 10-1670-277-23&P.  The release-away static line assembly is inspected and maintained as outlined in TM 10-1670-277-23&P/TO 13C5-28-2 and TM 10-1670-296-20&P/TO 13C7-49-2.

## Attaching The Deployment Line

2-27. The 3-foot (4-loop), type XXVI nylon webbing sling is used as the deployment line for DRAS
airdrop and connects the deployment parachute to the cargo parachutes.  Adapt the procedures as shown in Figure 2-29 to connect the deployment line to the deployment parachute.

1

rear outside carrying handles on the G-11D cargo parachutes.

## Section Vi - Release Assemblies Use

2-29. The cargo parachute release assembly separates the parachutes from the load when the load touches the ground.  The separation reduces the chance of the wind dragging or overturning the load.

## Description

2-30. The M-1 release is used when a DRAS load is rigged for airdrop.  This release is used with DRAS
rigged loads weighing up to 13,400 pounds suspended.



## Inspecting And Maintaining

2-31. The M-1 release is inspected and maintained as outlined in TM 10-1670-296-20&P/TO 13C7-49-2.
See the TM for specifics on inspection and maintenance.

## Operation

2-32. The operation of the airdrop cargo parachute release is given below.  The release works when the load touches the ground and upper suspension link tilts or moves to the side.  When the release tilts, the parachutes are released from the load.  Figure 2-32 shows how the release operates.



Note.  The face plate has been removed to aid in identification.

1
As the cargo parachute deploys, the arming wire lanyard is pulled.
2
The safety tie is broken and the arming wire is pulled from the timer.
3
The timer delays from 12 to 16 seconds.  This delay allows the load to stabilize itself under
the parachute.
4
When the timer winds down, it retracts its keys from the slots in the release.
5
 When the keys are retracted from their slots, the timer is free to fall within the release.
6
As the timer falls, it frees the toggle and upper suspension link.


7
When the load descends, the normal upright position of the M-1 release keeps the parachute connectors in place.  As the load touches the ground, the upper suspension link
tilts and allows the parachute connectors to pull free.
8
The released parachute stretches the dragline until the release drags to one side of the
load.  Then the dragline breaks.

## Preparing The M-1 Cargo Parachute Release

2-33. Test, attach, and safety the M-1 cargo parachute release as follows:
- **Testing timer.**  Before each use, seat, arm, and test the delay timer as shown in Figures 2-33
through 2-35.
1
Align and center the upper suspension link with the release side plates.
If the timer is not correctly seated in the upper position in the release when it is armed, the keys will not fit into the slots in the back side plate and could damage the timer.

2
Reach between the side plates, and slide the timer up until the toggles fit in the toggle lock
slides, making sure the timer slides freely.  You should be able to see the winding shaft of the timer through the guide block winder access hole.
1
Put the tip of a flat-tip screwdriver through the guide block winder access hole and into the
slot in the timer winding shaft.  Gently turn the shaft one-quarter turn to the right and stop, holding the shaft with the screwdriver.
Note.  If the winding shaft is hard to turn, hold the shaft with the screwdriver and move the timer around until the keys align with the slots in the back plate.

2
Hold the shaft, and push the arming wire down through the hole in the guide block and the hole in the winding shaft.
Note.  When the timer is correctly armed, about 1/2 inch of the arming wire can be seen through the slot below the guide block winder access hole.



Note.  A delay release timer will be tested before each use.



1
Pass a length of type I, 1/4-inch cotton webbing up between the release side plates, over
and around the center of the timer, and back down between the side plates.  The side plate
and a toggle lock slide have been removed to show how the webbing passes around the timer.  You may use a length of wire to help you pass the webbing around the timer.
Do not over tighten the face side plate. Make sure the bolts are tightened in an alternating sequence.

2
Hang the release in a straight, level position.
3
Tie a 10-ounce weight, such as a platform clevis with bolt or a parachute release
connector, without the nut and bolt, to the type I, 1/4-inch cotton webbing.

## Section Ix - Load Marking And Inspection Marking Rigged Load

2-40. Each rigged load must have a data tag prepared for it, and some rigged loads may require a Shipper's
Declaration for Dangerous Goods.  The center of balance must also be clearly marked on both sides of the platform.
- **Data Tag.**  A data tag is prepared and secured on the rear of each platform load.  Entries on the
tag are used by the Army and Air Force in making inspections and in finding causes for malfunctions.  The entries are also used to help the loadmaster determine where to place the load
in the aircraft.  Use a ballpoint pen or other waterproof marking device to record the following information on the tag:

Total rigged weight.

Height, including parachutes.

Width.

Overall length.

Overhang (specify front, rear, or side of load).

Longitudinal center of balance (measured from the front edge of the platform).
- Comply with the Shipper's requirements for Declaration of Dangerous/Hazardous Goods in
accordance with AFMAN 24-204 (I)/TM 38-250/NAVSUP PUB 505/MCOP4030.191/DLAI
4145.3.  The appropriate form is prepared and secured on each load that has any type of
hazardous material such as fuel, ammunition, or a battery.
- **Center of Balance.**  In addition to being included on the data tag, the longitudinal center of
balance must also be marked on the platform.  The vertical line of the symbol CB is placed at the center of balance on both sides of the platform.

## Section X - Transportation Of Rigged Loads Responsibilities

2-41. The using unit is responsible for coordinating transportation of the rigged load from the rigging site to the aircraft.  To prevent damage, loads must be lashed to the transporting vehicle and protected during transport.  The transporting force must ensure that the off-loading equipment is compatible with the aircraft to be used.

## Typical Loading And Transporting Equipment

2-42. Some of the equipment that may be used to load and transport rigged loads is listed below.
- **Materials-Handling Equipment**.  If a loading ramp is not available to use in loading the rigged
load onto the transporting vehicle, the load is hoisted aboard the vehicle.  The materials-handling equipment used to hoist the loads may include but are not limited to the 5-ton wrecker, the 10,000- or 15,000-pound-capacity warehouse crane, or the 10,000- or 15,000-pound-capacity forklift truck.
- **Transporting Vehicle.**  Any standard military truck or semi-trailer with sufficient cargo space
and payload capacity can be modified to transport a rigged load from the loading area to the cargo aircraft.  However, not all military trucks are compatible with the cargo-loading system of all types of cargo aircraft now in use.  Rigged platform loads require straight-in loading over a horizontally positioned ramp from a truck, a forklift, a flatbed, or a cargo loader.  Consequently, this may require transfer of the rigged load at the aircraft site before it is off-loaded into the cargo
aircraft. The following types of materials-handling equipment can be used to transport and/or offload platform loads:

The 6- or 10-ton cargo semi-trailer can transport loads rigged on airdrop platforms.

The 25,000-pound-capacity cargo loader can move the maximum weight of 25,000 pounds
up a 3-percent incline at 15 miles per hour.  It can be used for loading all aircraft.

The 40,000-pound-capacity cargo loader can move the maximum weight of 40,000 pounds
up a 3-percent incline at 15 miles per hour.

The 60,000-pound-capacity cargo loader (the Tunner) can move the maximum weight of
60,000 pounds up a 3-percent incline at 15 miles per hour.
Notes.  1.  The DRAS platform must be loaded centerline on the 25,000- and 60,000-
                  pound capacity loaders.

             2.  The 40,000-pound capacity loader requires the right side loads to be against
                  the loader's right side rails and left side loads must be against the loader's
                  left side rails.

# Rigging The Mass Supply Load On Dual Row Airdrop System Platform

## Description Of Load

11-1. The mass supply (fast box) load (Figure 11-1) is rigged on an 18-foot dual row platform.  The rigged weight is 14,120 pounds.  The load is rigged with two pre-constructed plywood boxes.  The forward box (box 1) has a minimum weight of 3,500 pounds and a maximum weight of 6,000 pounds.  The aft box (box 2) has a minimum weight of 2,800 pounds and a maximum weight of 5,000 pounds.  The load is 97 inches high, 94 inches wide, 216 inches long, and the center of balance is 90 inches from the front edge of the platform.  The load is rigged with two to four G-11D cargo parachutes.  The M-1 release is used with this load.  The minimum allowable weight is 8,100 and the maximum allowable weight is 14,500.

## Preparing Platform

11-2. Inspect, or assemble and inspect, a dual row airdrop platform with outrigger assemblies and outrigger platform support weldments according to TM 10-1670-268-20&P/TO 13C7-52-22 and as shown in Figure 11-2.

## Steps:

1. Starting at the front of each platform side rail, install clevises on the bushings bolted on
holes 2, 3, 4 (tripled), 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, and 30 (tripled).
2. Starting at the front of each platform side rail, number the clevises 1 through 29 on the
right side and 1A through 29A on the left side.
3. Label the tie-down rings according to Figure 2-2. 4. Construct four 30-foot lashings.  Route the free ends of the one 30-foot lashing through
platform tie-down rings A2 and B2.
5. Route the free ends of one 30-foot lashing through tie down rings A4 and B4. 6. Route the free ends of one 30-foot lashing through tie down rings A6 and B6. 7. Route the free ends of one 30-foot lashing through tie down rings A8 and B8.

## Building And Positioning The Mass Supply Boxes

# Rigging Three 500-Gallon Drums On A 18-Foot, Dual Row Airdrop System Platform For Low Velocity Airdrop (Lvad)

## Description Of Load

12-1. Three 500-Gallon Drums (Figure 12-1) are rigged on an 18-foot dual row platform.  Each drum is 62
inches long, 53 inches in diameter, and weighs 250 pounds empty.  Filled with 432 gallons of gasoline, each drum weighs 2,842 pounds.  The 500-gallon drum is used for both fuel and water storage.  The drum is cylindrical in shape with rounded ends.  The total rigged weight is 11,920 pounds.  The load is 97 inches high, 88 inches wide, 216 inches long, and the center of balance is 95 inches from the front edge of the platform.  The load is rigged with three G-11D cargo parachutes.  The M-1 release is used with this load. The minimum allowable weight is 11,400 pounds and the maximum allowable weight is 13,550 pounds.

Note.  Fill drums with no more than 432 gallons of fuel.  If the drums are filled with a fuel other than gasoline, the drum weight must be computed.

## Appendix Verifying The Center Of Balance On A Dras Platform Load Verifying The Center Of Balance

    A-1. The center of balance (CB) of a DRAS load must be verified and marked on each side of the
    platform.  The pole method and the calculation method are two ways of verifying the CB.  The instructions
    for these methods are given in Figures A-1 and A-2.


1
Mark the CB range on the side of the platform by placing a piece of adhesive tape 85 inches
from the front of the platform and another piece of adhesive tape 99 inches from the front of the platform.
2
Make a lift kit by placing four 11-foot (4-loop), Type XXVI nylon slings on a large clevis.  Attach
the lift kit sling legs to the 3-foot suspension slings on the front and rear of the platform with
medium clevises (if additional length is required add a second medium clevis through the first
medium clevis).  Ensure the lift kit slings are routed to the front of the front ACS and to the
rear of the rear ACS.
3
Raise the load and place a pipe or pole (minimum length of 8 feet and minimum diameter of 6
inches) under the load, perpendicular to the platform, in the CB range.
4
When the load balances, mark the CB on both sides of the platform.
Note.  The center of balance MUST be within the CB range of 85 - 99 inches from the front of the platform.



Note.  When using the calculation method, it is best to put a 4- by 4-inch piece of lumber across the front and rear ends of the platform.  The lumber should cross the center of any portable scales used.
If the 4- by 4-inch piece of lumber is unavailable, make sure that the forward and rear edges of the platform line up with the center of the scales.


Note.  Use the lift kit and instructions in Figure A-1, Step 2 to lift the load.



1
Place a portable scale under each corner of the DRAS platform.  Label the front scales A and
B and the rear scales C and D.  Place the scales the same distance from the front and rear
edge of the platform on both sides.
2
Add the weights of the front scales together (A + B = FW) (FW = Front Weight).
3
Add the weights of the rear scales together (C + D = RW) (RW = Rear Weight).
4
Add the front weight (FW) and the rear weight (RW) together.  This equals the total weight
(FW + RW = TW) (TW = Total Weight).
5
Measure the platform length in inches.  This equals the length (Length = L).
6
Multiply the length (L) by the rear weight (RW) and divide by the total weight (TW).  This
equals the center of balance (CB) in inches from the front edge of the platform.



Notes.  1.  Use the lift kit and instructions in Figure A-1, Step 2 to lift the load.
2.  When using the calculation method, it is best to put a 4- by 4-inch piece of lumber across
the front and rear ends of the platform.  The lumber should cross the center of any portable
scales used.  If the 4- by 4-inch piece of lumber is unavailable, make sure that the forward and rear edges of the platform line up with the center of the scales.

1
Mark the CB on both sides of the platform.
Note.  The center of balance MUST be within the CB range of 85 - 99 inches from the front of the
            platform.
