space. The cabin is 57.0 inches high and 54.0 inches
wide. Access is gained through the entrance door,
which measures 51.5 inches high and 26.7 inches
wide. The cabin section flooring will withstand a
loading of 200 pounds per square foot for items
supported on the seat tracks. Floor areas where seat
tracks
are
not
present,
walkways
and
aft
baggage/utility area, will only support 100 pounds per
square foot floor loads.
b. Standard Seating Arrangement. Seating is
provided for eight passengers. The seats may be
installed facing forward or aft. A side facing toilet is
installed across from the cabin entrance door,
separated from the passenger area by a partition. A
seat belt is provided and seating one passenger is

provided in the farthest aft portion of the cabin.
c. Ferry Fuel Configuration. The cabin area
may be converted to accommodate ferry missions by
removing the passenger seats and floor panels. The
tank platforms and ferry tanks are secured with seat
rail cargo rings on seat rails. The fuel tanks are
connected to the provisions already installed in the fuel
system.
6-12. PERSONNEL LOADING AND UNLOADING.
a. Seat Installation. The seats are mounted
on full length seat tracks to provide for quick removal
and reconfiguration of seats. The arm rests adjacent

The seats have reclining backs that may be adjusted
for individual comfort. Each seat back must be in the
full upright position for takeoff and landing.
b. Seat Belts and Shoulder Harnesses. The
pilot's and copilot's seats are equipped with shoulder
harnesses. The belt for the shoulder harness is in a Y
configuration with a single strap contained in an inertia
reel attached to the seat back. One strap is worn over
each shoulder and fastened by metal loops to the seat
belt buckle. Spring loading of the inertia reel allows
normal movement. A locking device will secure the
harness in the event of sudden forward movement or
impact action. Some passenger seats are equipped
with a lap seat belt and an over the shoulder
restraining belt.

otherwise, loads shall be computed as follows:
a. Combat Equipped Soldiers. Combat
equipped soldiers shall be computed at 275 pounds
per individual.
