(4) Loop the chain end of sling leg 4 through
the left rear lifting provision (closest to backhoe
operator’s seat), and insert link 5 into the grab-
hook. Wrap a felt sheet (cushioning material)
around the chain end of the sling leg and secure
with tape or nylon cord (fig 4-9).
(5) Cluster and tie or tape (breakaway tech-
nique) all sling legs above the FOPS to prevent
entanglement during hookup.
(6) Dual-hook procedures are identical except
two apex fittings are used—one for sling legs 1 and
2 and one for sling legs 3 and 4.
d. Hookup.
(1) vehicle should fly with rear end forward.
(2) Hookup team sits or squats on FOPS,
facing aft. The assistant hookup person discharges
static electricity with the static probe. The hookup
person places the apex fitting on the aircraft cargo
hook. Both persons carefully dismount and remain
beside the load as the helicopter removes slack
from the sling legs. When a successful hookup is
assumed, the hookup team briskly exits the area
underneath the helicopter.
(3) Dual-hook procedures are similar except
the hookup persons place two apex fittings on two
different cargo hooks. Apex fitting 1 goes onto the
forward cargo hook and apex fitting 2 goes onto
the rearward cargo hook. Do not use the center
aircraft hook.
