EXTRACTION LINES
9-6. The size and length of the extraction line used depends on the aircraft used and the size of the cargo
extraction parachute rigged for the load.
CAUTION
All multi-loop lines must have 15 feet of each end of the line, taped at 1
foot intervals. The measurement should begin from the end of the line
and the tape must be centered at each interval mark. Failure to comply
may cause an extraction line ply to get caught under the aircraft roller
and cause damage to the roller or extraction line.
CAUTION
While attaching the extraction line to the cargo extraction parachute,
ensure that the keepers on the extraction line and the adapter web are
pushed tight against the link and are taped in place with cloth-backed
tape. If a keeper is not present on the adapter web or extraction line,
tape in place with cloth-backed tape.
C-130/MC-130 AIRCRAFT
9-7. The primary method of airdrop platform extractions uses a 60-foot extraction line attached to a cargo

C-17 AIRCRAFT
9-9. Low velocity loads rigged for aerial delivery from the C-17 aircraft require an extraction line based
on the size of the extraction parachute. All extraction lines used on loads rigged for the C-17 aircraft must
be continuous, type XXVI nylon webbing. In addition to the extraction line and extraction parachute, the
C-17 requires a 15-foot drogue parachute and a 60-foot (1-loop) drogue line. The drogue line is not
required to be packed in a sling/extraction line bag. The C-17 utilizes a tow release mechanism which
connects the drogue line to the extraction parachute(s) and extraction line bag. All extraction lines must be
packed in a sling/extraction line bag. The C-17 can accommodate a single platform weight of up to 60,000
pounds with a total airdrop load weight of 100,000 pounds. The C-17 can accommodate up to 64 feet of
type V airdrop platforms.
• One 15-Foot Cargo Extraction Parachute. Attach a continuous 160-foot (1-loop), type XXVI
nylon extraction line rigged in accordance with TM 10-1670-286-20/TO 13C5-2-41. Due to the
use of the tow release mechanism, the rigging procedures are very detailed and should be
followed exactly.
• One 22-Foot Cargo Extraction Parachute. The 22-foot cargo extraction parachute needs a
continuous 140-foot (3-loop), type XXVI nylon webbing extraction line rigged in accordance
with TM 10-1670-286-20/TO 13C5-2-41.
• One 28-Foot Cargo Extraction Parachute. The 28-foot cargo extraction parachute needs a
continuous 140-foot (3-loop), type XXVI nylon webbing extraction line rigged in accordance
with TM 10-1670-286-20/TO 13C5-2-41.
• Two 28-Foot Cargo Extraction Parachutes. For a cluster of two 28-foot cargo extraction
parachutes, the extraction line requirements can change based on where the platform is located
in the aircraft. Normally the 140-foot (6-loop), type XXVI nylon webbing extraction line is
utilized. If the platform’s aft edge is located aft of FS 680 the 120-foot (6-loop), type XXVI
nylon webbing extraction line rigged in accordance with TM 10-1670-286-20/TO 13C5-2-41
may be used.

CAUTION
1. Failure to correctly route ties could result in non-deployment of
the parachutes.
2. If the load attaching end of the extraction line bag contacts the
aircraft floor during extraction, damage to the extraction line bag
may result.
Step:
2. Secure the extraction line bag to the load. Fold the extraction line bag bridle under the
extraction line bag before securing. Install three one turn single 1/2-inch tubular nylon
webbing restraint ties through the top and bottom extraction line bag panel connector links
and to convenient points on the load. Ties are routed on the load to prevent shifting of the
extraction system and secured using a trucker’s hitch with three alternating half-hitches
and an overhand knot in the running ends for each restraint tie.
CAUTION
The connector link(s) shall not be routed through the parachute
canopy bridle loop. Failure to comply could result in non-deployment
of the parachute(s).
3. Secure each extraction parachute(s) to the load. Route one turn double 1/2-inch tubular
nylon webbing restraint tie through the connector link(s), around the bag bridle strap(s),
and to a convenient point on the load. Secure with a trucker’s hitch, three alternating half-
hitches, and an overhand knot in the running ends.
4. Use the carrying handle to secure the extraction line bag to the load. Route one turn
double Type I, 1/4-inch cotton webbing restraint ties through the top and bottom carrying
handles on each corner of the load attaching end of the extraction line bag to a convenient
point on the load.
CAUTION
Link break cord ties for sequential airdrop must be of correct size.
Failure to comply could result in non-deployment of the
parachute(s).

5. Ensure link break cord ties are correct.
• For 15-foot extraction parachutes, remove 1/2-inch tubular nylon webbing link break
cord ties and replace with type III nylon cord.
• For three 28-foot extraction parachutes, remove 9/16-inch tubular nylon webbing link
break cord ties and replace with 1/2-inch tubular nylon webbing.
6. Prepare extraction line by removing temporary handling and transport ties.
Note: The extraction line is stowed in the extraction line bag with Type I, 1/4-inch cotton webbing
restraint ties. It may be necessary to cut a number of restraint ties to obtain a sufficient length of
extraction line to reach the EFTC. For in-flight rigging, the restraint ties should be cut on the
ground.
7. Pull the required length of extraction line from the load attaching end of the extraction line
bag for attachment to the EFTC.
8. Repeat steps 1 through 7 for additional platforms.

Chapter 10
Transportation of Rigged Loads
SECTION I-GENERAL INFORMATION
RESPONSIBILITIES
10-1. 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
10-2. 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 not limited to the 5-ton wrecker, the 10,000-
or 15,000-pound-capacity warehouse crane, or 5,000 pound through 15,000-pound-capacity
forklift trucks.
• 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 off-load 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.
The model M172 (lowboy) semi-trailer can load a C-130 aircraft. Any similar vehicle can
be used if its loading floor meets the cargo floor heights of the aircraft. For C-130 aircraft,
this is 39 to 42 inches.
SECTION II-RIGGING INFORMATION
MARKING RIGGED LOAD
10-3. 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.

10-1
Chapter 10
• Data Tag. A data tag is prepared and secured to each platform load near the extraction system.
Entries on the tag are used 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.
Overall length.
Overhang (specify front, rear, or side of load).
Longitudinal center of balance (measured from the front edge of the platform).
Type and size of extraction system.
• Shipper’s Declaration of Dangerous Goods. This 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.
TYPES OF INSPECTION
10-4. The types of inspections performed on a rigged load are the final rigger inspection, the before-
loading inspection, and the after-loading inspection as required by FM 4-20.102/MCRP 4-11.3J/NAVSEA
SS400-AB-MMO-010/TO
13C7-1-5 and AR
59-4/OPNAVINST
4463.24C/AFJ
13-210(I)/MCO
13480.1B. All rigged low-velocity loads must be inspected at prescribed intervals to make sure that the
loads and the equipment used on the loads are assembled and installed to meet the criteria outlined in the
specific rigging manual.
• Final Rigger Inspection (Shop Final). After the load has been completely rigged, a certified
Transported Force Rigger Inspector performs the final rigger inspection. This inspection is
accomplished before the rigged load leaves the rigging site to make sure it is rigged according to
the specific field manual/technical order for that particular load. This inspection should be
conducted by an inspector other than the rigger supervising the installation of parachutes and
extraction system. It is not necessary to use the DD Form 1748 (Joint Airdrop Inspection Record
[Platforms])-series inspection forms for this inspection.
• Before-Loading Inspection. A before-loading inspection must be performed on a rigged load
before it is loaded into the aircraft. This inspection is conducted jointly by a certified
Transported Force Rigger Joint Airdrop Inspector and a certified Air Force Joint Airdrop
Inspector. The inspectors use the proper joint airdrop inspection record, and both sign the
appropriate blocks to certify correct rigging of the load. When the rigged load is delivered to the
aircraft, the aircraft loadmaster checks the inspection form for completion and necessary
signatures before accepting the load.
• After Loading Inspection. After the loadmaster completes the loading and in-aircraft rigging,
the after-loading inspection is performed. This inspection is conducted jointly by a certified
Transported Force Rigger Joint Airdrop Inspector and a certified Air Force Joint Airdrop
Inspector, and the aircrew loadmaster. After the inspection is completed, the three inspectors
certify, by signing the form, that the load is ready to airdrop.
