(10) Check and clean drain holes regularly.
(11) Battery compartment and vent openings are especially prone to corrosion due to spilled
electrolyte. Fumes from overheated battery electrolyte will spread to adjacent areas and cause
rapid corrosion of unprotected surfaces. Frequent cleaning and neutralization of deposits will
minimize corrosion in this area.
(12) Magnesium parts are prone to corrosion. Special attention must be given to their surface
treatment, proper insulation (due to dissimilar metal corrosion), and paint coatings.
(13) Electrical components and connectors must be checked. Inspection frequency is based on
operational environment and past trouble.
(14) Skin joints and lap-overs are two areas that can trap and hold moisture. Corrosion in these
areas may go unnoticed unless particular attention is paid to them during inspection.
(15) Hoses, having an internal wire braid, which are located in a position where they are frequently
water soaked, need a protective treatment.
(16) Drilled holes and trimmed ends of sandwich panels must be protected. Use an inhibitor
solution or sealant application. Any gaps or cavities which allow dirt or moisture to enter must
be filled with sealant.
