5. It is necessary for you to know how fluid leaks affect 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 UNIT 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 leakage (Class I or II). Of course

consideration must be given to the fluid capacity in the item/system being

check/inspected. When operating with Class I or II leaks, continue to check fluid

levels as required on your PMCS. Class II leaks should be reported to your

supervisor or unit maintenance.
