  5-61. If the SPIES rope is not to be used immediately, it is neatly coiled and placed on the opposite side
  of the aircraft from the wood block. This ensures it will not become tangled or interfere with normal
  aircraft operations.
  5-62. If the helicopter has no cargo hook, or if the hook is not working properly, the team can still use
  the SPIES by doubling up on the cargo slings and Type IV links. This places two cargo straps side by side,
  for a total of four slings and four Type IV links.
  5-63. The team must use caution when using the UH-lH, because different configurations of the
  helicopter may make rigging difficult. Some of them have steps, which get in the way during both
  installation and operation. Others have rocket pods or mounted machine guns. The team might have to
  hook up two different UH-1s in two different ways.
  RIGGING OF A CH-46 OR CH-47
  5-64. The CH-46 and CH-47 require—
  • One SPIES rope with deployment bag.
  • Two 9-foot or two 11-foot, three- or four-loop slings.
  • Four Type IV connectors.
  • Eight oval snap links.
  • Heavy-duty tape (100-mph tape).
  • A 12-foot length of tubular nylon or one 12-foot sling rope.
  5-65. As they do with the UH models, the team attaches the SPIES rope using the slings and snaplinks
  (Figure 5-8). They pass the slings through the eye of the rope and attach it to the outboard cargo tie-down
  rings on the aircraft floor. They use two tie-down rings for each sling. They can use locally procured
  padding around the edge of the cargo hatch to protect the slings from damage.
  5-66. The team arranges the cargo straps to form two U-shapes. They place one strap forward of the
  cargo hole in the center of the aircraft floor, and the other one aft, toward the rear of the helicopter.
  However, varying positions of the tie-down rings could require them to adapt their rigging techniques
  accordingly. Once they finish the rigging, the cargo straps should hold the SPIES rope comfortably
