When documenting alterations, what must be captured in configuration records?

• A. Both major and minor alterations and their approvals; recorded in configuration records.
• B. Only major alterations require entry.
• C. No entries required for minor modifications.
• D. Only the cost difference recorded.

Answer: (A)

Configuration records are the official history of an aircraft’s configuration, so every alteration must be captured to maintain traceability and continued airworthiness. Both major and minor changes should be documented, along with the approvals that authorize them. Include a description of the alteration, the applicable data (such as ADs, STCs, service bulletins, or engineering orders), the change type (major or minor), the date and authority of the approval, and the relevant document references. Also note how the alteration affects the configuration—the equipment installed or removed, wiring or system changes, weight and balance implications, and any required inspections or maintenance. Recording all alterations with their approvals ensures an accurate, auditable record for future maintenance and regulatory compliance. The other options miss critical aspects by omitting minor changes, or by focusing only on cost.
