What FAR requires that an inspection checklist must be used in performing an inspection on an aircraft?

• A. FAR Part 21
• B. FAR Part 43
• C. FAR Part 91 Appendix D
• D. FAR Part 23

Answer: (B)

FAR Part 43 governs maintenance, preventive maintenance, rebuilding, and alterations, and it requires inspections to be performed in accordance with data and methods approved by the FAA. Using an inspection checklist is a practical and common way to apply those approved methods consistently, ensuring every required item is checked and properly documented. That alignment with approved data and a systematic approach is what makes Part 43 the correct choice.

Other parts cover different areas—how aircraft and products are certified, or design and operating rules—not the requirement for the method of performing an inspection.
