What is the required minimum for a checklist used during annual or 100-hour inspections?

The required minimum for a checklist used during annual or 100-hour inspections is established by 14 CFR Part 43. This regulation outlines the standards for maintaining, preventing, and altering aircraft, which includes the requirements for performing inspections. Specifically, it mandates that all maintenance procedures, including inspections, are to be performed in accordance with data acceptable to the FAA and that a checklist should be used to ensure compliance with the inspection requirements.

This regulation serves as the foundational legal framework governing aircraft maintenance practices, thus establishing the importance of following a specific checklist to ensure that all necessary inspections are completed systematically and thoroughly. The correct answer emphasizes that adherence to Part 43 is essential for maintaining safety and regulatory compliance in aviation maintenance activities.
