In aircraft configuration management, which combination of actions ensures accurate configuration?

• A. Update logbooks only during major modifications; ignore engineering approvals; maintain a single configuration file; discontinue older records.
• B. Maintain timely logbook entries for all changes; ensure alignment with engineering approvals; maintain master configuration records; perform regular reconciliation.
• C. Only rely on the master configuration; never update logbooks; ignore approvals.
• D. Rely on pilot memory for changes.

Answer: (B)

Maintaining accurate configuration hinges on traceability, authorized changes, and alignment between the aircraft and its official records. The best approach is to keep timely logbook entries for every change so there is a continuous, verifiable history; ensure each change has engineering approvals to validate and authorize the modification; maintain a master configuration record as the authoritative source of the aircraft’s configured state; and perform regular reconciliation to confirm the actual aircraft configuration matches the master records and approvals, correcting any drift promptly.

This ensures a clear, auditable trail, proper validation of modifications, and ongoing consistency between what is documented and what exists on the aircraft, which is essential for safety and compliance. Relying only on the master configuration without logging changes loses traceability; ignoring approvals bypasses necessary validation; skipping reconciliation allows discrepancies to accumulate; and relying on memory is unreliable for accuracy.
