Mandatory related maintenance will be indicated by which symbol?

Mandatory related maintenance will be indicated by which symbol?

• A. A circle
• B. An asterisk
• C. M
• D. #

Answer: (D)

The symbol chosen to indicate mandatory related maintenance is the hash sign. This marker flags that when you perform the listed maintenance action, you must also address related maintenance tasks on interconnected components or systems to preserve overall safety and function. In practice, replacing a part often requires inspecting or servicing adjacent elements that share interfaces or are affected by the change, and the hash signals you to plan for those related tasks. Other symbols like a circle, asterisk, or M generally serve different notes or indicators and do not specifically denote mandatory related maintenance.
