What documentation shows you exactly where to drill the holes for the pre-installed ground studs?

The engineering drawing is the critical documentation that provides specific details on where to drill holes for pre-installed ground studs. These drawings contain precise dimensions, locations, and annotations that are essential for ensuring accuracy in assembly processes. They often include essential information such as tolerances and other specifications related to structure and component placement.

In aerospace assembly, adhering to the engineering drawing is vital to maintain the integrity and safety of the aircraft. It allows mechanics to align components correctly and follow the necessary specifications laid out by the engineers, thereby reducing errors and ensuring compliance with aviation safety standards. Other documents like the operational manual, safety guidelines, and maintenance schedule may contain useful information but do not provide the specific, technical details necessary for drilling holes in the installation process.
