(2) Bolts, nuts and screws: Check them all for obvious looseness, missing, bent or broken condition. You can't
try them all with a tool, of course, but look for chipped paint, bare metal, or rust around bolt heads. Tighten any bolt, nut,
or screw that you find loose.
(3) Welds: Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad weld,
report it to direct support.
(4) Electric wires and connectors: Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Tighten loose connections and make sure the wires are in good shape.
(5) 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 also mean a leak. If a leak comes from a
loose fitting or connector, tighten the fitting or connector. If something is broken or worn out, either correct it or report it
to direct support (refer to the Maintenance Allocation Chart).
k. 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 your equipment. Learn
and be familiar with them and REMEMBER - WHEN IN DOUBT, NOTIFY YOUR SUPERVISOR!.
LEAKAGE DEFINITIONS FOR ORGANIZATIONAL PMCS
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 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 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.
WHEN OPERATING WITH CLASS I OR II LEAKS,
CONTINUE TO CHECK FLUID LEVELS AS
REQUIRED IN YOUR PMCS.
CLASS III LEAKS SHOULD BE REPORTED TO YOUR SUPERVISOR.
