EMBASSY OF THE UNITED STATES OF AMERICA No. IS STOCKHOLM, April 24, 1973 EXCELLENCY:

I have the honor to refer to conversations which have taken place between representatives of our two Governments relating to the reciprocal acceptance of airworthiness certifications, in the course of which discussions were held regarding appropriate actions necessary to work towards common safety objectives and to establish standards which will be as similar as practicable. It is my understanding that the two Governments have reached an agreement as set out below. It is also my understanding that this agreement does not relate to noise abatement or anti-pollution requirements.

Agreement Between the United States of America and Sweden Relating to Airworthiness Certifications

1. This Agreement applies to civil aeronautical products (hereinafter referred to as "products") and certain components referred to in paragraph 3 of this Agreement when such products or components are produced in one Contracting State (hereinafter referred to as the "exporting State") and exported to the other Contracting State (hereinafter referred to as the "importing State"). and to products produced in another State with which both Contracting States hare agreements similar in scope for reciprocal acceptance of airworthiness certifications.

b. In the case of a product produced in another State with which both Contracting States have agreements similar in scope for reciprocal acceptance of airworthiness certifications, if the competent aerocertification that the product conforms to the design covered by the nautical authorities of the State exporting the product provide a certificate or approval issued by the importing State and certify that the product is in a proper state of airworthiness, the importing State shall give the same ralidity to such certification as if the certification had been made by its own competent aeronautical nuthorities in accordance with its applicable laws, regulations and requirements.

This provision shall only apply to those components which are produced by a manufacturer in the exporting State pursuant to an agreement between that manufacturer and the product manufacturer in the importing State. Furthermore, it shall only apply in those instances where, in the judgment of the importing State. the component is of such complexity that determination of conformity and quality control cannot readily be made at the time that the component is assembled with the product.

4. The competent aeronautical authorities of the importing State et heation by the come shall have the right to make acceptance of any certification by the competent seronautical authorities of the exporting State dependent upon the product meeting any additional requirements which the importing State finds necessary to ensure that the product meets a level of safety equivalent to that provided by its applicable laws, regulations and requirements which would be effective for a similar product produced in the importing State. The competent aeronautical authorities of the importing State shall promptly advise the competent aeronautical authorities of the exporting State of any such additional requirements ã. The competent aeronautical authorities of each Contracting State shall keep the competent aeronautical authorities of the other Contracting State fully informed of all mandatory airworthiness modifi- TIAS 7611 Page 149

They shall also assist in analyzing those major incidents occurring on products to which this Agreement applies and which are such as would raise technical questions regarding the airworthiness of such products.

7. The competent aeronautical authorities of each Contracting State shall keep the competent aeronautical authorities of the other Contracting State currently informed of all relevant laws, regulations and requirements in their State.

8. In the case of conficting interpretations of the laws. remulations or requirements pertaining to certifications or approvals under this Agreement, the interpretation of the competent aeronautical authorities of the Contracting State whose law, regulations or requirement is being interpreted shall prevail.
