INTRODUCTION
2. Rust and Corrosion. Check the TWPS body and frame for rust and corrosion. If any bare metal
or corrosion exists, clean and apply a thin coat of oil, report to supervisor, or prepare an SF 368,
Products Quality Deficiency Report. Using key words such as "corrosion", "rust", "deterioration",
or "cracking" will ensure that the information is identified as a Corrosion Prevention and Control
(CPC) problem.
3. Bolts, Nuts, Screws. Check for obvious looseness, missing, bent or broken condition. Correct or
report to supervisor.
4. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If a bad
weld is located, report it to the supervisor.
5. Electrical Wires and Connections. Look for cracked, frayed, or broken insulation, bare wires and
loose or broken connections. Correct or report to supervisor.
6. Hoses and Fluid Lines. Look for wear, damage, and leaks. Make sure clamps and fittings are
tight. Wet spots or stains around fittings and connectors indicate leaks. Correct or report to
supervisor.
7. Leakage definitions are as follows:
a. Class I: For oil and fuel: Seepage of fluid (as indicated by wetness) but not enough to
form drops. For water: Seepage of fluid (as indicated by wetness) or leakage great
enough to form drops, but not enough to cause drops to fall.
b. Class II: For oil and fuel: Leakage of fluid great enough to form drops, but not enough to
cause drops to fall. For water: Leakage great enough to result in more than a slow
dripping from the leaking item.
c. Class III: For oil and fuel: Leakage great enough to cause drops to fall from leaking item.
For water: Rapid dripping or spray deemed to be a safety hazard or has the potential to
damage other equipment.
CAUTION
Operation is allowable with Class I and II leakage. Class II leaks should be
corrected when operational demands allow. Check regularly for any increase in
leakage.
Do not continue operation with Class III leakage.
