List three general methods for preventing corrosion on aircraft surfaces.

List three general methods for preventing corrosion on aircraft surfaces.

• A. Protective coatings/primer, sealants, and thorough cleaning/maintenance and inspection.
• B. Increase airspeed, reduce weight, change lubricant.
• C. Replace metal with plastic, daily repaint, avoid inspections.
• D. Use more fasteners, apply wax, wash weekly.

Answer: (A)

Corrosion prevention on aircraft relies on creating barriers, sealing joints, and removing corrosive elements through proper maintenance. Protective coatings and primer form a physical shield that keeps moisture, salts, and chemicals away from the metal. Primers are specially formulated to resist corrosion and to provide a good base for the topcoat, enhancing overall protection. Sealants fill gaps and joints so moisture cannot seep into crevices where corrosion starts. Thorough cleaning and regular maintenance remove corrosive agents like salt, dirt, and oils, and inspections catch early signs of corrosion so you can treat them before they spread. The other options don’t address corrosion directly: they either don’t prevent moisture contact, could introduce new problems, or rely on practices not tied to corrosion control.
