What type of inspection is required every 12 months for general aviation aircraft?

The correct answer is the Annual Inspection. This type of inspection is mandated by the Federal Aviation Administration (FAA) for general aviation aircraft and must be carried out every 12 calendar months. The purpose of the Annual Inspection is to ensure that the aircraft is in a condition for safe operation and to identify any potential issues that may affect its airworthiness.

During an Annual Inspection, a thorough examination of the aircraft is performed, which includes checking the airframe, engines, systems, and components as outlined in the manufacturer's maintenance manual and FAA regulations. The inspection is comprehensive and typically requires a certified mechanic to conduct it in accordance with the applicable regulations, ensuring that all parts of the aircraft are properly assessed.

Other types of inspections, such as a Routine Inspection or a Comprehensive Inspection, may occur but do not have the specific regulatory requirement of being completed on an annual basis like the Annual Inspection. Monthly Inspections are not a standard requirement in general aviation maintenance protocols, making the Annual Inspection essential for maintaining aviation safety and compliance.
