What type of inspection is specifically required to be completed before an aircraft can be deemed airworthy?

The correct answer is the Annual/100 Hour Inspection, as it is mandated by the Federal Aviation Administration (FAA) regulations for an aircraft to be considered airworthy. This inspection involves a thorough examination of the entire aircraft, including the powerplant and all its components, ensuring that everything is functioning correctly and safely.

The Annual/100 Hour Inspection is designed to verify that the aircraft meets all airworthiness standards and maintenance requirements. For operational aircraft, these inspections must be completed at least once every 12 calendar months (annual) or every 100 flight hours (100-hour), depending on the nature of the operation. Only after successfully completing these inspections can an aircraft be certified as safe to fly.

Other types of inspections, such as visual inspections or pre-flight inspections, do not encompass the comprehensive checks required for airworthiness certification. While a detailed inspection may uncover specific issues, it is not a regulatory requirement for airworthiness on its own. Thus, the distinction of the Annual/100 Hour Inspection as a prerequisite for deeming an aircraft airworthy is critical in maintaining safety in aviation operations.
