When is the 8130-3 form used to return an aeronautical product to service?

The 8130-3 form, also known as the Authorized Release Certificate, is crucial for ensuring that aeronautical products meet the necessary safety and regulatory standards before they are returned to service. This form is used in conjunction with major repairs and major alterations as defined by the FAA, which indicates that significant changes affecting the airworthiness of the product have been made.

By utilizing the 8130-3 form for both major repairs and major alterations, the integrity and safety of the aircraft are endorsed; it provides a traceable record that the work complies with regulations. This is important because major repairs and alterations may affect the airworthiness of the aircraft, necessitating a formal declaration that the work complies with aviation standards.

Routine maintenance, on the other hand, does not typically require an 8130-3 because it usually involves tasks that are less complex and do not significantly impact an aircraft’s fundamental operational capabilities. As a result, the form's application is specific to instances where major changes or repairs have occurred, supporting the broader goal of aviation safety.
