14 C.F.R. § 21.271 Airworthiness approval tags.
Title 14 - Aeronautics and Space
(a) A manufacturer may issue an airworthiness approval tag (FAA Form 8130–3) for each engine and propeller covered by §21.251(b)(4), and may issue an airworthiness approval tag for parts of each product covered by that section, if he finds, on the basis of inspection and operation tests, that those products conform to a type design for which he holds a type certificate and are in condition for safe operation. (b) When a new model has been included on the Production Limitation Record, the production certification number shall be stamped on the engine or propeller identification data place instead of issuing an airworthiness approval tag.
