What are common corrective actions for corrosion?

• A. Replacing the entire airframe
• B. Cleaning, applying inhibitors, patching or replacing
• C. Ignoring until next check
• D. Repainting only

Answer: (B)

Corrective actions for corrosion focus on removing the damage, slowing its return, and restoring the surface so it remains protected. Start with cleaning to remove corrosion products and contaminants and to prep the area. Then apply corrosion inhibitors to slow future attack and protect the cleaned surface. If the affected area is still structurally sound, patching a damaged section or replacing the component ensures the integrity of the structure. Replacing the entire airframe is not a typical remedy for common corrosion and would only come into play in extreme cases where the damage is widespread and safety is at stake. Repainting alone doesn’t fix corrosion, because it doesn’t remove the corrosion or stop it from continuing.
