„ Preparation. Prepare the load using the following steps:
─ Secure all internal cargo and loose items with Type III nylon cord or tie-down straps.
─ Lock the articulated steering unit with the steering cylinder locks.
Secure all doors, windows, and roof hatches in the closed position.
─ Tape all lights and glass fixtures including the windshield.
─ Fold side mirrors inboard and tie or tape as required.
─ Tape windshield wipers to windshield.
─ Secure all hoses and cables located between the two cars with tape or nylon cord to avoid
entanglement with sling legs.
─ Screw the lifting eyes in as far as possible while ensuring that they are pointing towards
the middle of each car. Tie diagonally opposing rings of each car together (for
example, the front right ring to the left rear ring) with Type III nylon cord.
─ Place the mud flaps in the up position and tape them in place.
─ Ensure the fuel tank is not over 3/4 full. Inspect fuel tank cap, oil filler cap, and battery
caps for proper installation.
„ Rigging. Rig the load according to the steps in Figure 5-1.
„ Hookup. The helicopter lands near the vehicle. The hookup team crawls under the
helicopter. The static wand person discharges the static electricity with the static wand. The
hookup person places the apex fitting onto the aircraft cargo hook. The hookup team then
moves clear of the helicopter but remains close to the load as the helicopter removes slack from
the sling legs. When successful hookup is assured, the hookup team quickly exits the area
underneath the helicopter to the designated rendezvous point.

Procedures. The following procedures apply to this load:
„
Preparation. Prepare the load using the following steps:
─ Place the howitzer in the forward/firing position.
If the firing platform is to be carried in the down position, follow these
steps:
─ Mark the wheel hubs with tape at the center of gravity (CG). The CG is located 6 inches
behind (towards the lunette) the center of the hub.
─ Mark the center of the firing platform along the length (lunette to muzzle) and width
(side to side) with strips of tape. Ensure the hand holes (used to secure the
ammunition boxes) are equally spaced on either side of the long axis of the
gun.
─ Roll the howitzer onto the firing platform. Align the CG masking tape with the side to
side tape strips. The wheel knock-off hub must be horizontal. Engage both parking
brakes.
─ Connect the firing platform to the weapon. Tie the ammunition boxes together with
Type III nylon cord. Secure the two ammunition boxes (if carried) by routing a CGU-
1/B tiedown strap through the platform hand holes and the carrying handles of each
box. Pad the CGU-1/B where it rubs on the boxes and platform.
─ Pad and tape the trailing edge of the platform when carrying an accompanying load in an
A/22 cargo bag or a cargo net.
Secure the sight cover to the dial sight with tape or Type III nylon cord.
─ Secure the firing platform (if carried), hand spike, and jack to the trail assembly with
Type III nylon cord.
─ When the detachable field spade is attached to the permanent spades, ensure the two
locking pins are installed and locked. Route and tie a length of Type III nylon cord
through the key ring of the cable and around the end of the locking pin.
─ When moving the howitzer without an A/22 cargo bag or a cargo net load, extend the
chain on sling leg 3 by removing the chain length and coupling link from sling leg 4
and attaching them to the end of the chain on sling leg 3.
─ When moving the howitzer with an accompanying load and using sling leg 4 on the
accompanying load, extend the chain on sling leg 3 by adding an additional length of
chain with a coupling link from a 25,000-pound capacity sling set.

Procedures. The following procedures apply to this load:
„ Preparation. Prepare the load using the following steps:
─ Ensure the stabilizers are in the firing position.
─ The spades may be in the up (stowed position) or down ( firing position).
─ Secure the air hoses and electrical cable to the supporting structure with Type III nylon
cord.
─ Stow and secure all equipment with tape or Type III nylon cord.
─ Ensure the barrel is in the firing position.
─ Extend the sling leg chains by connecting one additional chain length to each chain on
the sling set with coupling links.
„ Rigging. Rig the load according to the steps in Figure 6-13.
„ Hookup. The hookup team stands on top of the gun carriage. The static wand person
discharges the static electricity with the static wand. The hookup person places the web ring
onto the cargo hook. The hookup team then carefully dismounts the howitzer and remains close
to the load as the helicopter removes slack from the sling legs. When successful hookup is
assured, the hookup team quickly exits the area underneath the helicopter to the designated
rendezvous point.
Note. The helicopter must approach the howitzer over the spades.

Certified Single-Point Rigging Procedures for Howitzers and Weapons Systems
„ Derigging. Derigging is the reverse of the preparation and rigging procedures.
RIGGING STEPS
1. Position the web ring on top of the forward end of the breech. Route outer sling legs 1 and 2
to the front of the howitzer and inner sling legs 3 and 4 to the rear. Sling legs 1 and 3 must
be on the left side of the load.
2. Loop the chain end of sling leg 1 through the left front lift provision located on the left side of
the barrel. Place the correct link from Table 6-13 in the grab hook. Repeat with sling leg 2
through the right front lift provision. Secure all excess chain with tape or Type III nylon cord.
3. Loop the chain end of sling leg 3 through the left rear lift provision located on the left side of
the supporting frame near the left spade. Place the correct link from Table 6-13 in the grab
hook. Repeat with sling leg 4 through the right rear lift provision.
4. Cluster and tie (breakaway technique) the sling legs in each sling set together to prevent
entanglement during hookup and lift-off.
