1-10. LEAKAGE CLASSIFICATION AND DEFINITION
It is necessary for you to know how fluid leakage affects the status of the Roller. The following are types/ classes of leakage an
operator needs to know to be able to determine the status of the Roller. Learn these leakage definitions and remember-when in doubt,
notify your supervisor.
CAUTION
· Equipment operation is allowable with minor leakages (Class I or II) except for fuel
leakage. Consideration must be given to fluid capacity in the item/system being
checked/inspected. When in doubt, notify your supervisor.
· When operating with Class I or II leaks, continue to check fluid levels as required in your
PMCS.
· Any fuel or class III leaks should be reported immediately to your supervisor.
