During disassembly, labeling components helps with what objective?

• A. Speeding up reassembly.
• B. Providing a color-coded map for maintenance.
• C. Documenting the weight of each component.
• D. Maintaining traceability and preventing mixing serviceable and unserviceable parts.

Answer: (D)

Labeling components during disassembly ensures traceability throughout the maintenance process and prevents mixing parts that are serviceable with those that are unserviceable. When each piece is marked with its origin, orientation, and status, technicians can reassemble correctly, verify what was inspected or replaced, and quarantine items that must not go back into service. This safeguards safety, integrity, and compliance with procedures. The other options miss the primary purpose: labeling isn’t mainly to speed up reassembly, create a color-coded map, or record weight, none of which address ensuring the right parts with the right status are kept separate and trackable.
