What is the best time to prevent corrosion?

Preventing corrosion at the design stage is critical because decisions made during this phase have a lasting impact on the materials and construction of the aircraft. By selecting corrosion-resistant materials and applying appropriate design principles—such as avoiding areas where moisture can accumulate or ensuring that coatings and sealants are applied correctly—engineers can significantly reduce the likelihood of corrosion developing later.

Choosing the right materials tailored to specific environmental conditions encountered during operation is essential. Additionally, incorporating features that facilitate drainage and aeration further aids in minimizing corrosion risks. Prevention at the design level sets the foundation for the entire lifecycle of the aircraft, making it the most effective time to address potential corrosion issues before they can arise.

In contrast, while manufacturing is important for the application of protective measures, maintenance focuses on addressing existing corrosion, and inspection involves assessing for corrosion that has developed. These activities are reactive rather than preventive and cannot eliminate the risks established at the design stage. Thus, the design phase is undeniably the optimal time to implement corrosion prevention strategies effectively.
