What should be reviewed at the beginning of each step in the assembly process?

Reviewing the engineering drawing and work instructions at the beginning of each step in the assembly process is crucial for several reasons.

First and foremost, these documents provide the technical specifications and details necessary for the assembly task at hand. The engineering drawing contains essential dimensions, tolerances, and part identification, ensuring that the mechanic understands exactly how the components fit together. This can prevent errors in assembly that may arise from misinterpretation or misunderstanding of the parts involved.

Moreover, the work instructions outline the specific procedures to follow during assembly, including the methods, techniques, and quality checks that need to be performed. By confirming these details before proceeding, a mechanic can ensure that they are fully prepared and that the assembly will meet both safety and quality standards.

This initial review serves as a foundation to build upon in the assembly process, reducing the risk of mistakes and promoting efficiency. Ensuring that all requirements and details are clearly understood before starting helps create a smoother workflow and supports adherence to best practices in aerospace assembly.
