b.
Bolts, Nuts, and Screws. Check them all for obvious looseness, missing, bent, or broken condition. You can't try
them all with a tool, but look for chipped paint, bare metal, or rust around boltheads. If you find one you think is loose,
tighten it, or report it to unit maintenance if you can't tighten it.
c.
Electrical Wires and Cable Connectors. Look for bare wires, and loose or broken connectors. Report defects to
unit maintenance.
d.
Fluid Lines. Look for wear, damage, and leaks. Make sure clamps and fittings are tight. Wet spots and stains
around a fitting or connector can mean a leak. If a leak comes from a loose connector, tighten it. If something is broken
or worn out, report it to unit maintenance.
e.
Leakage Definitions. It is necessary for you to know how fluid leakage affects the status of your equipment. The
following are definitions of the types/classes of leakage you need to know to be able to determine the status of you
equipment. Learn and be familiar with them. When in doubt, notify your supervisor!
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 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 leakage (Class I or II) of any fluid except fuel. Of
course, consideration must be given to the fluid capacity in the item being checked/inspected.
When in doubt, notify your supervisor.
When operating with Class I or II leaks, continue to check fluid level more often than required in
the PMCS.
Class III leaks should be reported to your supervisor or unit maintenance.
