CHAPTER 4
AIR TRANSPORTABILITY GUIDANCE
4-1. Scope
This chapter provides air transportability guidance
for movement of the SEE, HME, and HMMH. It
covers significant technical and physical character-
istics and safety considerations. Also, it prescribes
the materials required to prepare, load, and un-
load the SEE, HME, and HMMH when trans-
ported in the C–130, C–141, and C–5 US Air Force
aircraft and the Boeing 747 Civil Reserve Air
Fleet (CRAF) aircraft.
4-2. Maximum Use of Aircraft Capac-
ity
Additional cargo, including personnel within al-
lowable load limits and restrictions prescribed by
pertinent safety regulations, may be transported
with these vehicles on US Air Force aircraft.
4-3. Applicability
a. US Air Force Aircraft. When prepared for
loading as described in paragraph 4-5, the SEE,
HME, and HMMH are transportable in C-130,
C-141, and C-5 aircraft.
b. Tiedown Devices.
The SEE, HME, and
HMMH will be tied down according to section IV
of applicable procedures in TO 1C-XXX–9.
c. Loadmaster. The loadmaster will ensure that
the loaded equipment is secured according to
restraint criteria outlined in TO 1C–XXX–9.
NOTE
Air Force aircraft loads in this manual
are illustrated to a minimum restraint of
3 g forward, 1.5 g aft, 1.5 g lateral and 2
g vertical. (Reference 1C-XXX-9 and
MIL-STD-1791.)
4 - 4 . S a f e ty
In addition to safety precautions
chapter 3, the following precautions
SEE, HME, and HMMH:
a. Ensure that the fuel tanks are
contained in
apply for the
not less than
one-fourth or more than three-fourths full.
b. Check each vehicle carefully to ensure that
all loose items are properly secured.
c. Check each vehicle to ensure there are no
fluid leaks.
d. Check all tiedown provisions and attached
structural members for any damage.
e. Check tire pressure to ensure tires are at
recommended highway pressure.
f. Check batteries to ensure they are protected
against short circuits and secured so that leakage
of acid cannot occur (reference TM 38–250, para
8-47a). Also, check the fuel tanks and hydraulic
systems to ensure they comply with TM 38–250.
WARNING
Fire extinguishers must be readily avail-
able during all loading and unloading.
WARNING
Provide proper ventilation during loading.
Prolonged inhalation of exhaust fumes
could be fatal.
WARNING
Do not allow the vehicle to exceed 3 miles
per hour (walking speed) inside the air-
craft or on the loading ramps.
4-5. Preparation of Equipment
a. Fold both mirrors and secure them with rope
to the roll over protection structure (ROPS).
b. Secure rear attachments with 1/2-inch wire
rope (safety cable) and two clips, when shipped in
the travel position. Install wire rope taut (not
tight) around the ROPS (or tiedown provision as
directed) and rear attachment to restrain the
attachment in case the mechanical lock is not
engaged or fails.
4-6. Transport by US Aircraft
a. The SEE, when shipped in C–130 and C–141
aircraft, will have the backhoe attachment in the
operational configuration. The SEE should be
backed into the C-130 and C-141 aircraft using
two qualified operators. One driver operates the
tractor and the other operates the backhoe, adjust-
ing height during loading and unloading opera-
tions. Each SEE requires two stacks of parking
shoring (2 x 6 inches x 4 feet, two per stack)
between the front end loader and the aircraft floor.
Also, place two stacks of shoring (2 x 6 inches x 4
feet, two per stack) under lowered bucket and
aircraft floor.
b. The HME and HMMH, when shipped in
C–130 and C–141 aircraft, must be in the travel
configuration.
(1) HME. Install 1/2-inch wire rope (safety
cable) through ROPS and over entrenched attach-
ment, forming a loop. Secure the loop by pulling
and installing the wire rope taut (not tight) with
two 1/2-inch clips. Each HME requires two stacks
