(d) Corrosion
Carefully examine any cable for corrosion that has a broken wire in a section not in
contact with wear producing airframe components such as pulleys, fairleads, etc. It may
be necessary to remove and bend the cable to properly inspect it for internal strand
corrosion as this condition is usually not evident on the outer surface of the cable. Replace
cable segments if internal strand rust or corrosion is found.
Areas especially conducive to cable corrosion are battery compartments, lavatories, wheel
wells, etc., where concentrations of corrosive fumes, vapors, and liquids can accumulate.
NOTE: Check all exposed sections of cable for corrosion after a cleaning and/or metal-
brightening operation has been accomplished in that area.
(e) Cable Maintenance
CAUTION: TO AVOID REMOVAL OF CORROSION-PREVENTATIVE COMPOUNDS
AND CABLE INTERNAL LUBRICANT, DO NOT USE VAPOR
DEGREASING, STEAM CLEANING, METHYLETHYLKETONE (MEK)
OR OTHER SOLVENTS.
CAUTION: DO NOT OIL CONTROL CABLES.
Frequent inspections and preservation measures such as rust prevention treatments for
bare cable areas will help to extend cable service life. Where cables pass through
fairleads, pressure seals, or over pulleys, remove accumulated heavy coatings of corrosion
prevention compound. Provide corrosion protection for these cable sections by lubricating
as specified in the Lubrication Chart, Section II.
