6-4-11. Litter Support Brackets.
Refer to figure 6-4-5 for litter installation. Four litter sup-
port brackets are permanently attached to each litter pole
and each litter strap. The brackets are spaced 18 inches
apart. A locking device in each bracket secures the litter
handles in place. The locking device consists of a handle
clip, a slotted locking bar, and a locking handle. The
locking handle is hinged to the lower jaw of the bracket.
The slotted locking bar is hinged, cam fashion, to the
locking handle. The handle clip is hinged to the upper jaw
of the bracket and has a hook end which is engaged in
one of the slots in the locking bar. When the locking
handle is moved down, it forces the locking bar up and
releases tension on the handle clip. When the locking
handle is moved up, it pulls the locking bar down and
forces the handle clip to a positive grip on the litter han-

Twelve litter poles are provided for use in adapting the
helicopter for medical evacuation. An attachment fitted to
the bottom of each pole has two indentations, on oppos-
ing sides, which fit between two studs located in a floor
channel. The upper rear side of the pole contains two
keyhole slots by which the pole is anchored to studs on
the seatback support tubes. A metal spring retainer in-
side the pole locks under one of the studs when the pole
is installed. This prevents accidental dislocation of the
pole. The retainer is released for litter pole removal by
pulling the grommet which protrudes from the front of the
pole. When not in use, the litter poles may be stowed at
Twelve litter straps are used with the litter poles to sup-
port the litters. The straps can be adjusted upward or
downward by slide adjusters near the upper and lower
ends of the straps. All of the straps are fitted at the top
with slipover hooks which are fastened to brackets in the
strap stowage recesses. The lower end of each strap has
a fitting for attaching the strap to a tiedown stud on the
floor. The straps are stowed in the overhead recesses
directly over the floor studs to which the straps will be
attached. The stowage recesses are covered with can-
vas flaps which are zipped along two sides.
6-4-13. Litter Loading.
The loading of litters will be accomplished through the
lowered aft cargo door and ramp. The forward litter tiers
should be loaded first, top to bottom, then progressively
rearward. Litter patients requiring in-flight medical care
should be positioned to enable access to injuries requir-
ing attention. If the helicopter is to be loaded with a com-
bination of troops and litter patients, the litter patients
should be positioned to the rear of the troops.
