Which part of the engineering drawing indicates where to install the lockwire?

The correct answer is that notes on an engineering drawing provide important information about the installation of lockwire. In many engineering drawings, notes are used to convey additional details that are not explicitly depicted in the graphical elements. These notes may include specifications for the type of lockwire to use, the locations on the assembly where the lockwire is required, and the proper methods for securing it.

These instructions are crucial for ensuring safety and reliability in aerospace applications, as lockwire is commonly used to prevent bolts and other fasteners from loosening due to vibrations or centrifugal forces. The specificity found in the notes helps mechanics understand exactly where to apply the lockwire on a particular assembly, facilitating compliance with regulatory standards and operational safety requirements.

Sections, hazard notes, and assembly instructions may contain useful information, but they do not typically provide the specific details required for lockwire installation. Sections focus on the cross-sectional views of components, hazard notes address potential risks, and assembly instructions guide the overall assembly process rather than pinpointing detailed fastening requirements.
