Which part of the regulation contains the scope and detail of the 100-hour inspection?

The correct answer emphasizes 14 CFR Part 43 appendix D, which specifically outlines the requirements for the 100-hour inspection for certain aircraft. This appendix provides detailed guidance on what needs to be included in these inspections, covering areas such as the necessary maintenance procedures, operational checks, and any other relevant information that is mandated for ensuring safety and compliance.

In the context of aviation regulations, it is crucial to refer to the appropriate sections that detail compliance requirements for inspections and maintenance. While other parts of the CFR relate to aspects of aviation regulations—such as airworthiness and registration—appendix D to Part 43 specifically addresses the 100-hour inspection, making it the go-to source for understanding the scope and detailed procedures involved.

This specificity helps maintenance personnel and operators ensure they are fully compliant with federal regulations, which is vital for the safe operation of aircraft. The clarity and structured guidance provided in this appendix serve as an essential tool for anyone involved in aircraft maintenance and inspections.
