Introduction - Does the 8130-3 Guidance Seem Confusing?

8130-3 was not designed to be solely a return-to-service document for use in complying with 14 CFR 43.9. Its other uses include export airworthiness approvals of Class II and Class III products; conformity determinations; identifying the airworthiness approval status of products (engines and propellers) in domestic transactions; airworthiness approval of parts and appliances under 14 CFR 21.305; and splitting bulk shipments of previously shipped parts.
