Class III leaks should be reported to your supervisor.
(1) Class I. Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
(2) Class II. Leakage of fluid great enough to form drops but not enough to cause drops to drip from item being
(3) Class III. Leakage of fluid great enough to form drops that fall from the item being checked/inspected.
2-7. GENERAL MAINTENANCE PROCEDURES.
As you perform your PMCS, keep in mind the following:
a. Cleanliness. Dirt, grease, oil, and debris only get in the way and may cover up a serious problem.
Bolts, Nuts, and Screws. Check them all for obvious looseness and missing, bent, or broken condition. You
cannot try them all with a tool, of course, but look for chipped paint, bare metal, or rust around bolt heads. If you
find a problem, report it to your supervisor.
c. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad weld,
report it to your supervisor.
d. Electrical Wires and Connections. Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Tighten loose connections and make sure the wires are in good condition. If you find a bad wire or
connector, report it to your supervisor.
Water Lines and Fittings. Look for wear, damage, and leaks. Make sure clamps and fittings are tight. Wet spots
show leaks, but a stain around a fitting or connector can mean a leak. If a leak comes from a loose fitting or
connector, or if something is broken or worn out, report it to your supervisor.
(1) Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any
problems with this item be reported so the problem can be corrected and improvements made to prevent the
problem in future items.
(2) While corrosion is typically associated with rusting of metals, it can also include deterioration of other
materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials
may be a corrosion problem.
(3) If a corrosion problem is identified, it can be reported using SF 368, (Product Quality Deficiency Report).
Check the box to indicate that the problem may be corrosion-related. Using key words such as "rust,"
"deterioration," "pitting," or "cracking" or even including color photos of the corroded area will aid problem
diagnosis and solution.
