Where can the radius of a bend typically be found?

The radius of a bend is typically found in AC 43.13 or in a relevant textbook, which are authoritative resources for guidance on aircraft repair and maintenance. AC 43.13, published by the FAA, provides standards and practices for aircraft repair, ensuring that structural repairs adhere to industry standards and safety requirements. Textbooks can also contain information regarding bending practices, including appropriate bend radii for various materials used in aircraft structures.

While aircraft maintenance manuals, engineering drawings, and manufacturing guides may provide various details about components and repair procedures, they may not specifically list the appropriate bend radii, which are more comprehensively addressed in the referenced literature. Understanding where to find the correct bend radius is crucial for ensuring that repairs do not compromise the structural integrity of aircraft components.
