(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 organizational maintenance.
(4) 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.
(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 mean a leak. If a leak comes from a loose
fitting or connector, tighten it. If something is broken or worn out, report to organizational maintenance.
j. 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 an operator or crew member needs to know to be able to determine the status
of his/her equipment. Learn, then be familiar with them and REMEMBER - WHEN IN DOUBT, NOTIFY YOUR
SUPERVISOR.
LEAKAGE DEFINITIONS FOR OPERATOR/CREW PMCS
Class I
See page of fluid (as indicated by wetness or discoloration) not 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.
WHEN OPERATING WITH CLASS l OR II LEAKS, CONTINUE TO CHECK FLUID LEVELS AS REQUIRED IN
YOUR PMCS.
CLASS III LEAKS SHOULD BE REPORTED TO YOUR SUPERVISOR OR TO ORGANIZATIONAL
MAINTENANCE FOR CORRECTIVE ACTION.
