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 organizational maintenance.
d.
Electric wires and connectors: Look for cracked or broken insulation, bare wires, and loose or
broken connectors. Tighten loose connectors and make sure the wires are in good shape.
e.
Hoses and fluid lines: Look for wear, damage, and leaks, and make sure clamps and fittings
are tight. Wet spots show leaks, of course. But a stain 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, report it to organizational maintenance.

It is necessary for you to know how fluid leakage affects the status of your vehicle. The following
are definitions of the types/classes of leakage an operator or crew member needs to know to be
able to determine the status of his/her vehicle. Learn and then be familiar with them, and
REMEMBER - WHEN IN DOUBT, NOTIFY YOUR SUPERVISOR!
Leakage Definitions for Crew/Operator
PMCS
Class I
Seepage of fluid (as indi-
cated by wetness or dis-
coloration) not great
enough to form drops.
Class II
Leakage of fluid great
enough to form drops but
not enough to cause drops
to drip from 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 leakages (Class I or II). Of course,
consideration must be given to the fluid capacity in the item/system being
checked/inspected. When in doubt, notify your supervisor.
