f. The designations left, right, front, and rear as
used in the preventive maintenance checks and
services (PMCS) indicate the side or end of the
centrifugal pump as viewed when facing the control
panel.
g. 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 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 organizational maintenance.
h. The Equipment is Not Ready/Available If: column contains the basis for classifying the equipment as not
ready/available because it is unable to perform its primary mission. An entry in this column will:
(1) Identify conditions that make the equipment not ready/available for readiness reporting purposes.
(2) Deny use of the equipment until corrective maintenance has been performed.
