Which document tracks all serial-number tracked components on an aircraft?

• A. AFTO 103
• B. AFTO 781J
• C. ACMS Configuration Report
• D. MDL

Answer: (C)

The question is about how you know exactly which parts with unique serial numbers are currently installed on an aircraft. Not all serial-numbered components are tracked in the same way, so there’s a specific document that serves as the authoritative record of the aircraft’s serial-number tracked configuration. The ACMS Configuration Report lists every serial-number tracked component installed on the aircraft, capturing the part identifiers, serial numbers, installation locations, and current status. This makes it the best source for confirming the exact hardware configuration, which is crucial for maintenance planning, troubleshooting, and configuration control.

AFTO 781J records maintenance actions and the parts replaced during those actions, including serial numbers for items involved in a given event, but it isn’t a single, current inventory of all serial-number tracked components. The other documents referenced aren’t intended to provide that comprehensive, up-to-date serial-number configuration record.
