SPECIFIC PMCS PROCEDURES - Continued
metal surfaces. Use Detergent, General Purpose, Liquid (WP 0120, Table 1, Item 7) and water when you
clean rubber, plastic, and painted surfaces.
Hazardous Waste Disposal. Ensure all spills are cleaned up IAW spill containment plan and disposed of
IAW using unit s Standard Operating Procedure (SOP).
Rust and Corrosion. Check metal parts for rust and corrosion. If any bare metal or corrosion exists,
clean and apply a light coat of Oil, Lubricating, OE/HDO-10 (WP 0120, Table 1, Item 13)
Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, missing, bent, or broken
condition. You cannot try them all with a tool, but look for chipped paint, bare metal, or rust around bolt
heads. If you find one is loose, tighten it.
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.
Electrical Wires, Harnesses, and Connectors. Look for cracked or broken insulation, bare wires, and
loose or broken connectors. Tighten loose connectors. Ensure wires are in good condition. Notify Field
Maintenance if wires are disconnected.
Hydraulic Lines, Hoses, and Fittings. Look for wear, damage, and signs of leaks. Check for loose
clamps and fittings. Wet spots indicate leaks, but a stain around a fitting or connector can also mean a
leak. If a leak comes from a loose fitting or connector, tighten it. If something is broken or worn out,
It is necessary for you to know how fluid leakage affects the status of the E-CHU. Following are types/classes of
leakage you need to know to be able to determine the status of your equipment. Learn these leakage definitions
and remember, when in doubt, notify your supervisor. Equipment operation is allowed with minor leakage (Class I
or II), except for fuel and brake fluid where no leaks are allowable. Consideration must be given to the fluid
capacity in the item or system being checked/inspected. When in doubt, ask your supervisor.
When operating with Class I or II leaks, continue to check fluid levels as required in the PMCS.
Class III leaks should be reported immediately to your supervisor.
Seepage of fluid (as indicated by wetness or discoloration) but not great enough to form
Leakage of fluid great enough to form drops, but not enough to cause drops to drip from
the item being checked/inspected.
Leakage of fluid great enough to form drops that fall from the item being checked/
