What documentation provides step by step directions for constructing a composite component?

The correct answer is planning papers. These documents are essential in the aerospace industry as they outline the complete manufacturing and assembly process for composite components. Planning papers provide comprehensive guidance that includes the sequence of operations, tools and materials needed, quality control measures, and safety considerations. This ensures that assembly mechanics have a clear understanding of how to construct a component effectively, maintaining consistency and adherence to safety and quality standards.

Technical drawings are often detailed representations of the component specifications and dimensions but do not inherently provide the operational steps necessary for assembly. Assembly instructions, while they may seem similar to planning papers, typically refer to a specific set of guidelines for putting together already defined parts, rather than the broader planning framework. Approval documents serve to verify and validate processes and components but do not include operational guidance on construction. Thus, planning papers are the most suitable documentation to provide step-by-step directions for constructing a composite component.
