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

The document that contains a minimum checklist for 100-hour inspections of engines is 14 CFR Part 43 Appendix D. This appendix outlines the specifications and requirements that need to be adhered to during the 100-hour inspection process. Specifically, it provides a standardized checklist that helps ensure that all essential components and systems of the engine are inspected and evaluated properly.

This regulation is critical for maintaining a consistent safety standard across the aviation industry, as it dictates the minimum requirements needed for thorough inspection. Such consistency ensures that every inspection performed meets federal safety guidelines, protecting both operators and the flying public.

In contrast, the other choices offer helpful resources related to aviation maintenance but do not specifically contain the checklist mandated for 100-hour inspections. The Aviation Regulations Handbook provides broader regulatory information, the Aircraft Service Manual may include specific maintenance tasks or procedures, and FAA Aircraft Maintenance Guidelines serves as a general resource for maintenance practices but lacks the prescribed checklist details found in 14 CFR Part 43 Appendix D.
