What does the FAA require for conducting a 100 Hr or Annual Inspection?

The Federal Aviation Administration (FAA) requires that for conducting a 100-hour or annual inspection, an Inspection Check List must be used. This requirement is in place to ensure that all necessary checks are performed systematically and that no important tasks are overlooked. The use of a checklist helps maintain consistency and thoroughness during the inspection process, thereby enhancing safety by ensuring that all critical components of the aircraft are inspected according to established standards.

A checklist typically includes specific tasks and inspection criteria that align with regulatory guidelines and manufacturer recommendations. By using this organized approach, mechanics and inspectors can ensure that each part of the aircraft is reviewed adequately, reducing the chances of errors or omissions.

Other options may imply different practices. While averaged checklists might be useful informally, they do not meet the regulatory standard set forth by the FAA for official inspections. There are no specifications that allow for inspections to occur without a checklist, which makes the "no specific requirements" option incorrect. Lastly, an inspection manual, although it can provide guidance, does not serve the same role as a checklist for ensuring that all inspection items are completed during the required inspections.
