What additional requirement does CFR Part 43 specify for an inspection checklist for rotorcraft?

CFR Part 43 outlines specific regulations regarding the maintenance, preventive maintenance, and alterations for aircraft, including rotorcraft. The requirement for the inspection checklist to include specific items from Appendix D is particularly significant because Appendix D provides detailed criteria related to the inspection of items that are crucial for the safe operation of rotorcraft.

Including specific items from Appendix D ensures that all critical areas are inspected consistently, meeting safety standards and operational efficiency. The items listed are essential for thorough inspections, reflecting the unique complexity and risk associated with rotorcraft operations and their respective maintenance needs.

This requirement underscores the importance of having a detailed and standardized approach to inspections, thereby helping to minimize oversights that could lead to safety issues. In doing so, inspectors can better adhere to the regulatory framework designed to promote aircraft safety and reliability.

The other choices, such as needing manufacturer approval for checklists, inclusion of engine checks, or having the checklist signed by an IA, do not provide the same level of regulatory specificity as the requirement to include items from Appendix D. While these other aspects may be relevant in certain contexts, they do not address the core regulatory focus that this question highlights – the importance of adhering to established standards in the inspection process for rotorcraft.
