Why is technical cleanliness crucial in aerospace engineering?

Technical cleanliness is a critical factor in aerospace engineering. The cleanliness of components and systems directly impacts their performance and reliability. Contaminants such as dust, dirt, fibers, or particles can lead to malfunctions or even component failure. Technical cleanliness is particularly important in the aerospace field. In aerospace, components and systems must operate under extreme conditions such as vacuum, temperature fluctuations, and radiation. Contaminants not only cause malfunctions but also degrade material quality. To minimize these risks, aerospace engineering has developed stringent technical cleanliness guidelines and standards, including cleaning procedures, packaging regulations, and control measures.
