Various cable system malfunctions
may be detected by analyzing pulley conditions.
These include such discrepancies as too much tension, misalignment, pulley bearing
problems, and size mismatches between cables and pulleys. Examples of these condition are
shown in the figure.
Inspect fair-leads
for wear, breakage, alignment, cleanliness, and security. Examine cable routing
at fair-leads to ensure that defection angles are no greater than 3° maximum. Determine that all
guides and anti-abrasion strips are secure and in good condition.
CORROSION AND RUST PREVENTION.
To ensure a satisfactory service life for aircraft
control cables, use a cable lubricant to reduce internal friction and prevent corrosion.
CABLE MAINTENANCE.
Frequent inspections and preservation measures such as rust-
prevention treatments for bare carbon steel cable areas, will help to extend cable service life. Where
cables pass through fair-leads, pressure seals, or over pulleys, remove accumulated heavy coatings
of corrosion-prevention compound. Provide corrosion protection for these cable sections by
lubricating with a light coat of grease or general purpose, low-temperature oil.
