Which of the following options describes an inspection authorization holder's ability to approve repairs?

An inspection authorization holder can approve repairs when they follow approved technical data because this ensures that repairs meet the required safety standards and are in compliance with the applicable regulations. This is fundamental to ensuring the airworthiness of the aircraft, as the use of approved technical data provides a standardization for maintenance practices. It signifies that the repair process, materials, and components used adhere to the manufacturer’s specifications or are recognized by the FAA. This responsibility is integral to the holder's role in maintaining aviation safety and regulatory compliance.

Other choices do not align with the regulatory framework governing repairs. The ability to approve any repairs on any aircraft, or only repairs of their own work, fails to recognize the importance of following defined processes and standards. Similarly, the claim that alterations can be approved regardless of compliance directly contradicts the adherence to established regulations that govern aircraft maintenance and safety practices.
