PMCS INTRODUCTION (continued).
1.
Cleanliness. Dirt, grease, oil, and debris may get in the way and cover up a serious problem. Use
drycleaning solvent on all metal surfaces and soapy water on rubber components, as necessary.
2.
Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness and for missing, bent,
or broken conditions. Look for chipped paint, bare metal, or rust around bolt heads. If any part seems
loose, tighten it. If any part is broken or missing, replace it.
3.
Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If a bad weld
is found, notify your supervisor.
4.
Electric Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or
broken connectors. Tighten loose connectors and make sure wires are in good condition. Repair/
replace any bad wires or connectors.
5.
Hydraulic Lines and Fittings. Look for wear, damage, and leaks; make sure clamps and fittings are
tight. Wet spots are an indication of leaks. Stains around a fitting or connector can mean a leak. If a
leak comes from a loose fitting or connector, tighten it. If something is broken or worn out, repair it
or replace it.
6.
Damage. Damage is defined as any condition that affects safety or would make the CBT
unserviceable for mission requirements.
d.
Fluid Leakage.
1.
Leakage definitions:
Class I
Seepage of fluid (as indicated by wetness or discoloration) not great enough to form
drops.
Class II
Leakage of fluid great enough to form drops, but not enough to cause the drops to
fall from the item being checked/inspected.
Class III
Leakage of fluid great enough to form drops that fall from the item being checked/
inspected.
CAUTION
Equipment operation is allowable with minor leaks (Class I or II). Of course,
you must consider the fluid capacity of the item/system being checked/inspected.
When in doubt, notify your supervisor.
When operating with a Class I or II leak, frequently check the fluid level of the
system.
All leaks should be reported to your supervisor and repaired.
