When should the surface of an aircraft component be inspected for flaws?

Inspecting the surface of an aircraft component for flaws is crucial to ensure the overall safety and integrity of the aircraft. Conducting this inspection before painting provides a significant advantage. It allows any surface damages, such as scratches, dents, or corrosion, to be identified and addressed prior to applying a protective coating.

If flaws are present and not detected until after painting, they might be obscured, making it more challenging and time-consuming to correct issues later. This could lead to degraded coating performance and potential corrosion, which could compromise the structure's integrity over time.

Inspections during the manufacturing process are important as well, but focusing on the surface condition right before painting ensures that the component is ready for final finishing without any hidden imperfections. Addressing flaws at this stage leads to improved durability and safety in the long run, making it an essential step in maintenance and pre-flight checks.
