What should logbook entries for electrical maintenance include?

• A. Work performed.
• B. Part numbers only.
• C. Work performed, part numbers, manuals referenced, and service actions taken.
• D. Date only.

Answer: (C)

Recording complete maintenance actions requires clear, traceable documentation of what was done and how. The work performed describes the actual tasks and their scope, giving a precise picture of the action taken. Including the part numbers identifies exactly which components were installed or replaced, which is essential for future part compatibility checks, warranty, and sourcing. Noting the manuals or task references used shows that the correct procedures and standards guided the work, helping verify that the right steps were followed. Recording the service actions taken captures the results of inspections, tests, adjustments, torque values, and verifications, so the aircraft’s condition after maintenance is clear. Together, these elements create a complete, auditable history that supports safety, regulatory compliance, and future maintenance decisions.
