Aviation Institute Of Maintenance (AIM) Block 16 Practice Exam

What is the function of a placard or data plate on an aircraft component?

To provide critical information such as part number, limits, operating instructions, and safety warnings To identify color To store maintenance logs To indicate installation date

Correct Answer:

To provide critical information such as part number, limits, operating instructions, and safety warnings

Explanation:

Placards or data plates carry essential, permanent information directly on the component. They identify the exact part with a part/serial number and specify the limits, operating instructions, and safety warnings that must be followed. This allows technicians to verify you’re using the correct part, ensure it’s operated within approved parameters, and perform the proper procedures for installation and maintenance. The safety warnings help prevent hazardous mistakes and support regulatory compliance. Color identification, storing maintenance logs, or indicating installation date aren’t the function of the data plate, which is focused on providing the critical data needed for correct identification, safe use, and traceability.
