(a)Class I: Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
(b) Class II: Leakage of fluid great enough to form drops but not great enough to cause drops to drip from the item
being checked/inspected.

CAUTION
Equipment operation is allowable with minor leakage (Class I or II). Of course, you must consider the

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 or direct support maintenance.
