Leakage definitions for operator/crew PMCS shall be classified as follows: 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 item being checked/inspected. Class Ill Leakage of fluid great enough to form drops that fall from the item being checked/inspected. Equipment operation is 14 allowable with minor Ieakage (Class I or II). Of course, you must consider the fluid capacity in the item/system being checked/inspected. When in doubt, notify your supervisor. When operating with Class I or Class II Ieaks, continue to check fluid Ievels as required. For PMCS performed on an operating time basis, perform PMCS as close as possible to the time in- tervals indicated. For units in continuous operation, perform PMCS before startlng operation if contin- uous operation will extend service Interval past that which is showen. 3-8.
