When a Part 145 repair station uses FAA Form 8130-3 to return a component to service after a major repair, what is required?

When a Part 145 repair station uses FAA Form 8130-3 to return a component to service after a major repair, it must include a maintenance release as a required attachment. This is essential because the maintenance release provides assurance that the component has been restored to a condition for safe operation according to regulatory standards. It documents accomplishments of repairs or alterations, validates that the work was performed in compliance with approved procedures, and indicates that the necessary inspections and tests were completed satisfactorily.

In context, the inclusion of a maintenance release helps ensure traceability and accountability, which is crucial in aviation maintenance practices. It serves as an official record that can be referenced if issues arise later, thereby enhancing safety and regulatory compliance. The use of FAA Form 8130-3, along with the maintenance release document, forms a comprehensive return-to-service package, ensuring that all regulatory requirements have been adequately addressed.

The other options fail to recognize the necessity for documented verification that a component has met all applicable standards before being deemed airworthy. Thus, the requirement for a maintenance release is a critical part of the process, ensuring solid adherence to the FAA's regulations and aviation safety protocols.
