What should be done after deburring holes before reassembling the parts?

After deburring holes, it is essential to visually inspect the pieces to ensure that there are no remaining burrs, foreign objects, or imperfections that could affect the integrity and proper fit of the assembly. This inspection helps maintain the quality standards required in aerospace assembly, where even minor defects can lead to significant issues during operation. It provides a final check to confirm that the parts are clean, properly shaped, and ready for safe reassembly.

While cleaning with water may seem like a plausible step, it is not the primary focus immediately after deburring, as debris may still be present that isn’t removed solely by cleaning. Ignoring alignment would compromise the assembly's functionality and safety, and leaving the assembly as is would not ensure that all necessary post-deburring checks have been made. Visual inspection is a critical best practice that enhances the reliability and safety of the finished aircraft components.
