and cables should be inspected for corrosion attack and
cracking of the wire insulation. Cable shielding is
particularly prone to corrosion.
Ram Air Turbine (Rat) Compartments. Maintenance
personnel should inspect RAT compartments for
moisture traps. They should inspect all mounting
hardware, electrical connectors, terminal boards,
junction boxes, and the RAT itself for signs of corrosion
that may have been caused by moisture spray.
Electrical Bonding and Grounding Straps. The
bonding and grounding straps used on aircraft and
electrical equipment are major sources of galvanic
corrosion. Usually, this strap is made of a metal that is
dissimilar to the areas to which it is attached. Thus, a
galvanic couple is created. Unless maintenance
personnel take proper preservation action, this
couple, in the presence of moisture, corrodes at a rapid
