During routine UH-60 maintenance, how is corrosion prevention performed on the airframe?

• A. Clean the surface, apply corrosion-inhibiting compounds, inspect for corrosion, remove and treat, apply primer and paint as needed; maintain protective coatings.
• B. Skip cleaning and rely only on cosmetic paint.
• C. Apply primer only and skip corrosion inhibitors.
• D. Disassemble the airframe to remove corrosion.

Answer: (A)

Corrosion prevention on the UH-60 airframe is a disciplined, multistep surface protection process. It starts with thorough cleaning to remove dirt, grease, salt, and other contaminants that can trap moisture and initiate corrosion. Next, corrosion-inhibiting compounds are applied to create a chemical barrier against oxidation. The surface is then inspected for any signs of corrosion; if found, those areas are removed and treated to halt further damage, and the surface is prepped for coatings. Finally, primer is applied to promote paint adhesion and add an additional protective layer, followed by the appropriate topcoat. Ongoing protection comes from maintaining the protective coatings and repairing any coating damage to prevent moisture intrusion. Skipping cleaning, relying only on cosmetic paint, applying primer without inhibitors, or disassembling the airframe are not suitable for routine prevention because they leave contaminants, fail to provide continuous protection, or are unnecessary for normal maintenance.
