FLUID LEAKAGE
It is necessary for you to know how fluid leakage affects the status of the E-CHU. Following are types/classes of
leakage you need to know to be able to determine the status of your equipment. Learn these leakage definitions
and remember, when in doubt, notify your supervisor. Equipment operation is allowed with minor leakage (Class I
or II), except for fuel and brake fluid where no leaks are allowable. Consideration must be given to the fluid
capacity in the item or system being checked/inspected. When in doubt, ask your supervisor.
When operating with Class I or II leaks, continue to check fluid levels as required in the PMCS.
Class III leaks should be reported immediately to your supervisor.
Leakage Definitions
Class I
Seepage of fluid (as indicated by wetness or discoloration) but 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
the item being checked/inspected.
Class III
Leakage of fluid great enough to form drops that fall from the item being checked/
inspected.
