b. AF Phase 2 Final Report by ShockTech, 9 September 2021

2. The Air National Guard – Air Force Reserve Command Test Center (AATC) tested the REAP with their Research & Development Team at US Army Combat Capabilities Development Command Soldier Center, Natick, MA. The test was completed to allow a reusable REAP pad in lieu of single use energy dissipating material on container delivery systems (CDS).

3. This exception to policy governs AF UAT loads rigged for CDS and Container Ramp Loads (CRLs) only. Loads covered in TO 13C7-1-11 are the only loads authorized for use for UAT loads.

4. All units utilizing the REAP will follow the attached procedures and this memorandum.

UAT units conducting airdrop using REAP shall send an email to the POC below with the overview of the UAT airdrop, Pre/post drop condition of the load, and type of load airdropped . Adverse results of using the REAP versus Energy Dissipating Material (EDM) are mandatory.

5. This memorandum expires on 22 December 2022.

RIGGING UNILATERAL AIRDROP TRAINING (UAT) A-22

CARGO BAG LOADS WITH REUSABLE ENERGY

ABATEMENT PAD (REAP)

SECTION I – RIGGING A-22 LOADS WITH REAP

DESCRIPTION OF LOAD

1-1. A typical load is rigged for airdrop using an A-22 cargo bag. Typical loads include rations, repair parts, water cans, and other small items. Items to be dropped may be rigged in their original shipping container or may be repacked for airdrop. A-22 container loads must weigh between 501 and 2,200 pounds, excluding the weight of the parachute. The load is rigged with one G-12E cargo parachute with a 68-inch diameter pilot parachute or a 26-foot cargo parachute. See TO 13C7-1-11, Chapter 2 for aircraft capabilities and limitations.

NOTE: REAP can only be used in lieu of honeycomb on AF UAT Loads ONLY.

PREPARING DROP ITEMS

1-2. Prepare the drop items according to the load’s sensitivity. Items must be well padded to prevent damage during airdrop. Items must also be padded or containerized to prevent them from falling out of the container during airdrop.

PREPARING SKID BOARD

1-3. Prepare a locally fabricated skid board as shown in Figure 1-1.

Notes.

This drawing is not drawn to scale.

All dimensions are given in inches.

Use only AC grade plywood for skid boards.

① Place a ¾- or 1- by 48- by 48-inch piece of plywood on a flat surface.

② Drill four ½-inch holes on each side as shown above.

③ Measure 3 inches in from each corner of the skid board and make a diagonal cut.

④ Cut eight 8-foot lengths of ½-inch tubular nylon webbing. Route one length through hole A from the bottom and the other end through hole B from the bottom. Even the ends.

⑤ Repeat step 3 for holes C and D and remaining sides.

POSITIONING REAP

1-4. Position the REAP as shown in Figure 1-2. Utilize 9 blocks for a single A-22 load.

CAUTION

The bottom layer of REAP must be 2 inches from all sides to allow proper operation of the CVRS.

① Center 9 blocks of REAP in a 3 by 3 pattern on the skid board.

Figure 1-2. REAP Positioned on Skid Board

POSITIONING A-22 CARGO BAG SLING, COVER, AND LOAD

1-5. Position the A-22 cargo bag sling, cover, and load as shown in Figure 1-3.

① Center the A-22 cargo bag sling facing down on the honeycomb. When the webbing is laid facing down, the webbing sewn to the scuff pad will be on the bottom.

② Center the optional A-22 cargo bag cover on the sling assembly.

③ Center the load on the cover and honeycomb.

SECURING A-22 CARGO BAG COVER

1-6. Secure the A-22 cargo bag cover over the load as shown in Figure 1-4.

Note. This drawing is not drawn to scale.

① Bring up sides to cover the load. Fold under any side that will obstruct the bag cover securing ties. (Not Shown)

② Using a length of type III, nylon cord. Route the cord as shown. Pull it tight and make a surgeon’s knot and bow knot. Secure the knot and the excess with masking tape. Make sure one running end is exposed.

SECURING A-22 CARGO BAG SLING

1-7. Secure the sling assembly according to Figure 1-5.

Notes.

This drawing is not drawn to scale.

Friction adapters cannot be on corners.

The middle support web should remain vertical.

① Bring the short tie-down strap over the load and route it through the friction adapter. Route the long tie-down strap the same way. Apply tension to the friction adapter and secure the excess as shown in TO 13C7-1-11, Figure 1-3.

② Route the two lower lateral straps through the friction adapter. Apply uniform tension and secure the excess as shown in TO 13C7-1-11, Figure 1-3.

③ If the top lateral strap is higher than the load, tighten the strap loosely on top of the load as shown above. If the load is higher than the lateral strap, place the strap over the corner and tighten it.

④ If the strap cannot be placed over the corner, fasten the strap around the load sides. Pass a length of type I, ¼-inch cotton webbing through each rectangle portion of the sling assembly D-rings and tie the ends together with a surgeon’s knot and locking knot. Ensure the type I, ¼-inch cotton webbing stays on top of the corners of the load.

SECURING SKID BOARD TO A-22 CARGO BAG

1-8. Secure the skid board to the A-22 cargo bag as shown in Figure 1-6. When tightening straps, make sure excess tension is not applied causing the sewn portion at the intersection of lateral straps and support web to separate.

① Starting at the left side, take tie-down A and diagonally tie it around the intersection of the lower lateral strap and fourth support web. Use three half-hitch knots and an overhand knot in the running end.

② Route tie-down B around the fifth support web and lower lateral strap intersection diagonally.

Pull the excess slack out and tie it with a trucker’s hitch knot and an overhand knot in the running end. Cut excess webbing, leaving end approximately 6 inches long.

③ Repeat step 1 for tie-down D and secure it to the second intersection on the lower lateral strap.

④ Repeat step 2 for tie-down C and secure it to the first intersection on the lower lateral strap.

⑤ Repeat steps 1 through 4 for the other tie-down straps (not shown).

① Attach all four suspension webs as shown above. Route snap fastener from outside to inside.

Wrap masking tape around the snap fasteners.

② Tape all suspension webs together near the free end using masking tape.

③ Tape all suspension webs together as close as possible to the snap fasteners but at least 2 inches above the snap fasteners using masking tape.
