Welds: Look for loose or chipped paint, rust or gaps where parts are welded

it to your supervisor
Leakage: It is necessary for you to know how fluid leaks affect the status of

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
. Equipment operation is allowable with minor leakages (Class I or
II). Of course, you must consider the fluid capacity in the
item/system being checked/inspected.
. When operating with Class I or Class II leaks, continue to check
fluid levels as required in your PMCS.
. Class III leaks should be reported to your supervisor.
Leakage definitions for unit PMCS
Seepage of fluid (as indicated by wetness or discoloration) not great enough
to form drops.
Leakage of fluid great enough to form drops but not enough to cause drops
to drip from the item being checked/inspected.
Leakage of fluid great enough to form drops that fall from the item being
