What does "corrosion" refer to in the context of aircraft maintenance?

In the context of aircraft maintenance, "corrosion" specifically refers to the deterioration of materials, typically metals, due to chemical reactions. This process is predominantly influenced by exposure to moisture and air, which facilitate the chemical interactions that lead to rust and degradation. Corrosion can have severe implications for the structural integrity and safety of an aircraft, making it crucial for maintenance personnel to identify and address corrosion issues promptly.

Understanding corrosion is vital for maintaining the longevity and operational efficiency of aircraft, as untreated corrosion can lead to structural failures and increased repair costs. Maintenance practices often include regular inspections, protective coatings, and corrosion prevention methods to mitigate these risks and ensure aircraft safety.
