Is it necessary to consult the engineering drawing to identify which fasteners and collars to use in the assembly?

Consulting the engineering drawing is essential in identifying which fasteners and collars to use during assembly. Engineering drawings provide specific details about the components required for an assembly, including exact sizes, materials, specifications, and configurations of fasteners. They ensure that the correct parts are used, which is crucial for maintaining the integrity and safety of the aerospace structure. Incorrect fasteners or collars can lead to structural failures or compromised performance, making it imperative to follow the specifications outlined in the engineering drawings closely. This practice is not just a best practice but a critical aspect of adhering to industry standards and regulations in aerospace manufacturing. It's important to recognize that relying solely on memory or general knowledge when selecting fasteners can introduce risks, and consulting the drawings mitigates those risks effectively.
