Leakage. 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 III Leakage of fluid great enough to form drops that fall from the item being checked/inspected.
NOTE
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 in doubt, notify
your supervisor.
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 unit maintenance.
