What should you do after removing corrosion from an aircraft surface?

After removing corrosion from an aircraft surface, it is essential to restore protective surface films. This step is crucial because corrosion protection is key to maintaining the integrity and longevity of aircraft materials. When corrosion is removed, the underlying surface can be exposed to environmental factors, which may lead to re-corrosion or further degradation if not treated properly.

Restoring protective surface films can include applying protective coatings, sealants, or other treatments that prevent moisture and contaminants from penetrating the metal. These protective measures ensure that the aircraft surface remains resilient against future corrosion and adheres to safety standards.

While applying a new layer of paint may seem like an appropriate action, it often comes after ensuring that the surface is adequately treated and protected. Inspecting for structural damage is important as well, but it typically should follow the initial corrosion removal before any protective coatings are reapplied. Leaving the surface untreated would increase the risk of corrosion returning, compromising the safety and structural integrity of the aircraft.
