a. It is important to know how fluid leakage affects the status of the CBT. The following are types/classes of
leakage an operator must know to determine if the CBT is mission capable. Learn these leakage definitions.
When in doubt, notify your supervisor.
Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
Leakage of fluid great enough to form drops, but not great enough to cause drops to drip
from the item being inspected.
Class III Leakage of fluid great enough to form drops that fall from the item being inspected.
Equipment operation is allowable with minor leakages (Class I or Class 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
Class III leaks should be reported immediately to your supervisor or Unit
Equipment operation is allowed with minor (Class I or Class 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
