MM3671, Lesson 2
2.9. Close the doors from the inside and check for the penetration of light from outside. If light penetrates,
look for the source of entry. If it is a hole or a crack, it indicates that the MILVAN is unserviceable. Now,
open the doors so that you can continue your inspection of the interior.
2.10. The cargo restraint system consists of eight horizontal slotted rails, intermittently spaced and
welded on each side wall, and 25 independent load bracing crossbeams that interlock into the side rail
slots. They are shown in figure 2-13, here in position to illustrate their use.
Vertical slotted rails must be welded to the sides of the end frame (figure 2-14). This arrangement permits
adjustment of the bracing to fit the loading requirements.
Figure 2-13. Crossbeams in Place.
Figure 2-14. Vertical Slotted Rail.
Horizontal and vertical rails must not be damaged to the point that their slots would prevent the
crossbeams from locking in the slots (figure 2-15). Check the rails for distortion and for possible
looseness. Check for faulty or cracked welds. Any of these defects is cause for rejection.
Inspect the load bracing crossbeams to make sure that the locking mechanism is operable and that the
beams are not bent, crushed, or bowed (figure 2-16). Defective crossbeams must be repaired or replaced
before the MILVAN can be accepted.
