Remove suspension systems and chin straps. (See Figure 19-1.)
Wash the helmets 10-15 minutes in a 0.5 percent soap solution (NSN 7930-00-129-0815) at a water
temperature of 120° F (40° C). Rinse them in clear warm water until soap is removed. Allow them to dry
thoroughly in a temperature not exceeding 140°F (60°C).
Examine the rubber edging for cuts, slits, and areas of non-adherence. If it is determined that the edging is
no longer serviceable, then remove the edging by using a heat gun to loosen the adhesive where the
edging ends butt together at rear of helmet. Once one end of the edging has been loosened, grasp edging
with pliers and pull edging away from helmet while still using heat gun to loosen adhesive. Remove any
remaining adhesive before installing new edging to helmet. The rubber edging, slightly longer than the
periphery of the helmet, should be opened up and wound around a cylinder so that the inside of the
channel is exposed. The inside of the edging should be lightly abraded with a wire brush and the adhesive
cited in Section Ill applied. Adhesive should also be applied to the helmet edge. When the adhesive
becomes tacky, the edging should be applied to the helmet edge. The application of the edging should
start at the bench mark at the rear of the helmet and follow the periphery of the helmet completely around
to the starting point at the rear of the helmet. The edging should be cut so that the ends butt each other.
Examine the helmet shell for chipped paint. Repair these places without stripping the paint from the
helmet. Using the paint cited in Section Ill and the procedure described in Section II paragraph 6, apint the
helmet, except that the second coat should cover the entire outside of the helmet (including rubber
edging).
(a) Examine the inside and outside surfaces of the helmet shell for blistesrs. If it is determined that the
defects limited to the outside plies only (on the inside and outside of the shell), and the defects do not
extend beyond one ply deep, then the helmet shell can be repaired. If damage extends beyond one ply
deep, then the helmet shell is not serviceable. Repair of the above defect is accomplished as follows:
1. Remove paint around the immediate area of damage, making sure not to cause additional raising
of fibers.
2. Make a single cut in the blister (fabric ply) with a sharp knife sufficiently long enough to allow
placing of epoxy resin under the cut ply.
3. Insert epoxy resin (cited in Section Ill) under ply in sufficient quantity to achieve a strong bond.
4. Apply pressure to defect area to ensure mating of plies.
5. After epoxy has cured, sand lightly and blend smoothly into shell.
6. Apply second coat of resin if required.
7. Apply paint as described in paragraph 19-6.
