What is the main purpose of drilling in aircraft repairs?

The main purpose of drilling in aircraft repairs is to create holes for the insertion of various hardware. This is essential in the assembly and maintenance of aircraft, as it allows technicians to secure components together using rivets, bolts, or other fasteners, ensuring structural integrity and safety during flight.

Drilling is a critical operation in aircraft maintenance because correctly placed holes enable the secure attachment of parts, facilitating repairs or modifications as needed. Without accurately drilled holes, the effectiveness of fasteners would be compromised, leading to potential failures in the aircraft's structure.

While decorative patterns, cutting metal sheets, or smoothing surfaces may serve specific functions in other contexts, they do not align with the primary objective of drilling in the realm of aircraft repair.
