The holder of an IA cannot approve the data for major repairs; his/her role is to:

The holder of an IA (Inspection Authorization) plays a critical role in ensuring that all necessary approved data is accessible and available for the approval process related to major repairs. This function is crucial as it guarantees that any maintenance work carried out adheres to regulatory standards and safety measures established by aviation authorities.

Making approved data available helps in the decision-making process for repair work, ensuring that all personnel involved have the correct and necessary information before proceeding. This oversight is essential to maintain compliance and safety within the aviation maintenance framework, as the holder of the IA must not just be knowledgeable but also ensure that all documentation is in order and that the data used for repairs is properly vetted and sanctioned.

On the other hand, the other options relate to functions that do not align with the responsibilities of an IA holder as per regulatory standards and practices. Accessing and filing documents is a support activity, conducting personal inspections exceeds the IA holder's role, and preparing reports may fall under other aspects of maintenance oversight but is not a primary responsibility of the IA holder. These activities do not encompass the critical function of ensuring available approved data for repair approvals.
