What symbol is used to enter a general fault on a PMCS form?

• A. Circle
• B. Circled X
• C. X Mark
• D. Cross X

Answer: (D)

In PMCS forms, you use a specific symbol to flag faults that require maintenance action. The general fault is shown with a cross X—two diagonal strokes forming an X across the item. This symbol is the standard way to indicate a general fault on the PMCS form, signaling that the item needs corrective maintenance.

The other marks don’t carry the same standard meaning. A plain circle, a circled X, or an X mark without the cross styling can be interpreted differently or may be used for other statuses on different checklists, which can lead to confusion during maintenance actions. The cross X is chosen specifically for clarity and consistency in signaling a general fault.
