LEAKAGE DEFINITIONS.
a.
It is important to know how fluid leakage affects the status of the trailer. The following are types/classes of
leakage an operator must know to determine whether the trailer is mission-capable. Learn these leakage
definitions. When in doubt notify your supervisor.
Leakage Definitions for Operator/Crew PMCS
Class I
Seepage of fluid (as indicated by wetness or discoloration) not
great enough to form drops.
Class II
Leakage great enough to form drops, but not great enough to
cause drops to drip from item being inspected.
Class III
Leakage of fluid great enough to form drops that fall from the
item being inspected.
CAUTION
When operating with Class I or II leaks, continue to check fluid levels in addition to
that required in PMCS. Parts without fluid stop working or may be damaged.
b.
Equipment operation is allowed with minor (Class I or II) leakage. Fluid levels in an item/system affected with
such leakage must be checked more frequently than required in PMCS. When in doubt, notify your
supervisor.
c.
Report Class III leaks IMMEDIATELY to your supervisor.
