A common mistake when preparing for drilling in an assembly is not reviewing the drill bit size. Selecting the correct drill bit size is crucial as it ensures that the hole being drilled will accommodate the intended fastener or component accurately. An incorrectly sized bit can lead to improper fit, which can compromise the integrity of the assembly and may even require additional repair work or replacement of components.

Choosing the wrong drill bit can result in various issues, including excessive play in fasteners, stripping of threads, and weakening the overall structure of the assembly. Thus, reviewing the size of the drill bit before starting the drilling process is essential to achieve the desired outcome and maintain the safety and quality standards in aerospace assembly.
