CHAPTER 4
AIR TRANSPORTABILITY GUIDANCE
4-1. Scope
This chapter provides air transportability guidance for
movement of the 14- and 20-ton M915, M915A1,
M916, and M920 truck tractors. It presents examples
of tiedown diagrams and tiedown data for loading
these vehicles on US Air Force aircraft.
4-2. Maximum Utilization of Aircraft
Additional cargo, including personnel within allow-
able load limits and restrictions prescribed by perti-
nent safety regulations, can be transported with these
vehicles on US Air Force aircraft.
4-3. Safety
In addition to the safety precautions contained in
chapter 3, the following should be noted:
a.
The activity offering the vehicles for transport
will notify the aircraft commander or his designated
representative if ammunition or explosives are to be
transported within a vehicle.
b.
Fuel tanks must not be more than one-fourth full.
c.
The vehicle must be restrained for air transport
in accordance with the applicable procedures in section
IV of US Air Force TO lC-5A-9.
d.
Each vehicle must be checked carefully to ensure
that all loose items are properly secured in accordance
with restraint criteria.
WARNING
Proper ventilation must be provided during
loading and unloading of the vehicles. Pro-
longed inhalation of carbon monoxide fumes
may be fatal.
WARNING
Fire extinguishers must be readily available
during all loading and unloading operations.
CAUTION
Do not allow vehicles to exceed 3 miles per
hour on loading ramps or inside aircraft.
NOTE
Cargo loads depicted in this manual are re-
strained to the required minimum of 3g’s for-
ward restraint.
NOTE
In air loading, the center of gravity of each
vehicle must be determined and, where the
weight and/or measurement is critical, each
vehicle should be weighed or measured,
4-4. Responsibility
The loadmaster will ensure that loaded equipment is
secured in accordance with restraint criteria outlined
in TO 1C-5A-9.
4-5. Aircraft Capabilities
The 14- and 20-ton truck tractors can be transported
only in the C-5 aircraft provided parking shoring, at
least l/2-inch thick, is used under the front wheels.
Maximum tire pressure for airlift is restricted to 100
psi. Fuel tank and batteries must be prepared for air-
lift in accordance with the requirements of TM
38-250.
4-6. Typical Loads
The following tiedown diagrams (figs 4-1 through
4-2) and data tables (tables 4-1 through 4-2) are
based on acceptable methods that can be used as a
guide for loading and securing the 14- and 20-ton FOV
aboard US Air Force aircraft. Loads are based on
empty vehicles in reduced configuration.
4-7. Transport by US Army Aircraft
The M915 FOV trucks exceed the size and weight lim-
itations for transport by US Army fixed and rotary
wing aircraft.
