What is required for an individual to conduct a complete 100-hour inspection on an aircraft?

To conduct a complete 100-hour inspection on an aircraft, an individual must hold a mechanic certificate with both airframe and powerplant ratings. This certification ensures that the individual possesses the necessary skills, knowledge, and qualifications to perform comprehensive maintenance and inspection tasks on both the structural and engine components of an aircraft.

The regulation stipulates that only certified mechanics have the authority to conduct such inspections, as they have undergone extensive training in various aspects of aircraft maintenance. Holding both airframe and powerplant ratings is crucial, as the 100-hour inspection covers both the aircraft structure and its powerplant systems.

While other licenses, such as a private pilot license or a maintenance technician certificate, might provide certain skills or knowledge, they do not meet the regulatory requirements for performing this type of inspection. Additionally, inspector authorization certification allows individuals to approve and sign off on work performed but does not replace the need for a mechanic certificate to conduct the inspection itself.
