Prepare a parachute platform by cutting and positioning a 36- by 96-inch piece of
honeycomb on top of equipment box 3 flush with the rear edge. Make cutouts in this
piece where it comes in contact with the lashings on top of equipment box 3. Place three
additional pieces of 36- by 96-inch pieces on top of the first piece. Tape the 36-inch side
with 2-inch adhesive tape.
2
Cut and position four 6- by 96-inch pieces of honeycomb to the front of the 36- by 96-inch
pieces of honeycomb previously placed. Tape the 6-inch side with 2-inch adhesive tape.

Appendix
INSTALLING SUSPENSION SLING SAFETY TIES
Installing the suspension sling safety ties keeps the suspension slings from making contact with the
load. The procedures in this Appendix are different from those in FM 4-20.102/NAVSEA
SS400-AB-MMO-010/TO 13C7-1-5. An exception to FM 4-20.102/NAVSEA SS400-AB-MMO-
010/TO 13C7-1-5 is granted. The procedures in this Appendix must be followed. Safety tie
the rear suspension slings according to instructions shown below.
1
2
1
Cut two lengths of 1/2-inch tubular nylon webbing, making each long enough to reach
from the left rear suspension sling to the right rear suspension sling plus 8 feet. Split the
plies of the left rear suspension sling. Route two lengths of the 1/2-inch tubular webbing
through the plies of the sling from inboard to outboard about 3 feet.
2
Route the 3 foot running end from outboard to inboard around the inside plies and
around the outboard plies from inboard to outboard. Tie it in place on the inboard side
with three alternating half-hitches with an overhand knot in the running end.

3
Split the plies of the right rear suspension sling and route the running ends of the two
lengths of 1/2-inch tubular nylon webbing through the plies of the sling from inboard to
outboard. Pass enough of the webbing through the sling to take the slack out, but not
enough to keep the slings from hanging in their natural position.
4
Route the running end from outboard to inboard around the inside plies and around the
outboard plies from inboard to outboard. Tie it in place on the inboard side with three
alternating half-hitches with an overhand knot in the running end.
5
Tape the webbing to the slings with masking tape.
6
When using four-loop, type XXVI suspension slings, wrap each four plies with a 10-by 10-
inch piece of cotton muslin. Secure each wrap with one single turn of 1/4-inch cotton
webbing (not shown).
