Each person performing an annual or 100 hour inspection shall use a checklist that contains at least those items in the appendix of 14 CFR Part 43.

• A. 14 CFR Part 43 Appendix
• B. 14 CFR Part 39 Appendix
• C. 14 CFR Part 91 Appendix
• D. 14 CFR Part 21 Appendix

Answer: (A)

Maintenance checklists for annual and 100-hour inspections come from the FAA regulation that covers maintenance and alterations. Its Appendix lists the specific items that must be included, ensuring every inspection covers the same essential systems and components. That’s why this Appendix provides the required checklist for those inspections.

The other parts regulate different areas: one governs airworthiness directives, another covers general operating rules, and another deals with certification of aircraft and parts. None of those appendices provide the mandatory inspection checklist for annual or 100-hour inspections, so the Appendix to Part 43 is the correct source.
