How do maintenance terminology describe a fault vs a defect?

• A. A fault is an abnormal condition; a defect is a deviation from required specification or workmanship.
• B. A fault is cosmetic damage; a defect is a functional failure.
• C. A fault is intentional damage; a defect is random wear.
• D. A fault and a defect are the same thing.

Answer: (A)

In maintenance terminology, a fault is an abnormal condition within a system or component that indicates something isn’t operating as intended. A defect is a deviation from the required specification or workmanship, meaning the part or output doesn’t meet the design or quality standard. So the fault points to how the system is behaving, while the defect points to how the part was made or specified. This aligns with the correct choice, which defines a fault as an abnormal condition and a defect as a deviation from required specification or workmanship. The other options mischaracterize the ideas: cosmetic damage isn’t inherently about operational abnormality, a defect isn’t limited to just functional failure, faults aren’t defined as intentional damage, and faults and defects are not the same thing.
