LEAKAGE CLASSIFICATION AND DEFINITION
Extreme weather conditions, periods of high use, or combat conditions may dictate that PMCS is performed more
often than is required in the PMCS Tables.
As PMCS is performed, look for and be aware of an unusual amount of puddles, or unusually large puddles.
Excessive puddles could indicate a leakage problem.
It is necessary to know how fluid leakage affects status of fuel, oil, coolant, and hydraulic system. The following are
definitions of the type/classes of leakage necessary to know in order to determine status of the enhancement.
Learn, then be familiar with them and REMEMBER - WHEN IN DOUBT, NOTIFY THE SUPERVISOR.
Equipment operation is allowable with minor leakage (Class I or II). Consideration
must be given to the capacity in item/system being checked/inspected. When in
doubt, notify Supervisor. When operating with Class I or II leaks, continue to check
fluid levels as required in the PMCS. Class III leaks should be repaired per
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 that fall from item
Class III. Leakage of fluid great enough to form drops that fall from item being checked/inspected.
