GENERAL PMCS PROCEDURES CONTINUED
f.
Electrical Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Report loose connections and faulty wiring to your supervisor.
g. Hoses, Lines, and Fittings. Look for wear, damage, and signs of leaks. Check for loose clamps and fit-
tings. Wet spots indicate leaks, but a stain around a fitting or connector can also mean a leak. If a leak
comes from a loose fitting or connector, tighten it. If something is broken or worn out, correct it if authorized
by the Maintenance Allocation Chart (WP 0429). If not authorized, notify your supervisor.
h. Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of your machine. The
following are definitions of the types/classes of leakage you need to know to be able to determine the sta-
tus of your machine. Learn and be familiar with them and remember: when in doubt, notify your supervisor.
CAUTION
Operation is allowable with Class I and Class II leakage. WHEN IN DOUBT, NOTIFY
YOUR SUPERVISOR. When operating with Class I or Class II leaks, check fluid levels
more frequently. Class III leaks must be reported immediately to your supervisor. Failure
to follow this caution may result in damage to machine and/or components.
NOTE
Notify your supervisor of any leaks you cannot fix.
