13. 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.
14. 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.
15. 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, then be
familiar with them and REMEMBER - WHEN IN DOUBT, NOTIFY YOUR SUPERVISORI
Leakage Definitions for Crew/Operator PMCS
CLASS I
Seepage of fluid (as indicated by wetness r 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 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 OR TO ORGANIZATION- AL MAINTENANCE.
