Which of the following is not listed as a reference for load rigging?

• A. TM 4-48.12
• B. TM 4-48.09
• C. TM 4-48.10
• D. TM 4-48.11

Answer: (A)

When studying load rigging, the references you use are specific manuals that cover sling-load procedures, equipment, inspection, and operations. The manuals typically cited for rigging are the ones that directly address sling-load rigging topics. The reason the choice in question is not listed is that this particular manual is about a different subject and not part of the official rigging reference set. So while the other manuals focus on sling-load rigging details, this one does not, and thus isn’t included as a rigging reference. In practice, always verify which TM numbers are cited for rigging tasks, and focus your study on those that are explicitly relevant.
