Which maintenance symbol should be used when an ops check (IFOC) is required?

• A. Red X
• B. Red Diagonal
• C. Red Dash
• D. Red Circle

Answer: (C)

In this maintenance symbol system, the symbol choices communicate specific actions that must be taken or statuses of the item. When an ops check is required, the red dash is used. This symbol signals that a functional or operational verification must be performed before the item can be considered serviceable, ensuring the system operates correctly under its intended use. The dash is placed where it will be seen by the maintenance team or flight crew and stays in place until the IFOC is completed and the status is updated accordingly. The other symbols indicate different conditions and do not convey the need for an operational check. A red X denotes an unserviceable item that cannot be used, a red diagonal line represents a different kind of status or action, and a red circle points to other specific flags or requirements. None of these three specifically communicates that an operational check is required, which is why the red dash is the correct choice for an IFOC.
