Which of the following contains a minimum checklist for 100-hour inspections of engines?

The correct answer is based on the regulatory framework established by the Federal Aviation Administration (FAA) concerning maintenance procedures for aircraft. The 100-hour inspection is a specific type of maintenance requirement for certain aircraft and is governed under 14 CFR Part 43, which outlines the maintenance, preventive maintenance, rebuilding, and alteration of aircraft.

Appendix D of this part specifically details the requirements for the 100-hour inspection. It provides a checklist that ensures that the inspection meets all necessary safety and regulatory standards. This checklist is critical for maintenance personnel to follow, ensuring that all components of the aircraft, especially the engines, are inspected thoroughly and properly.

The other options pertain to different regulatory areas that do not specifically address the minimum checklist for 100-hour inspections. Each of those parts covers different aspects of aviation regulations, making them unsuitable for this particular requirement. The focus on the checklist for the 100-hour inspection found in Appendix D makes it the definitive source for ensuring compliance and safety in engine maintenance.
