The consolidated version of the U.S.-EU Cooperation Agreement on Civil Aviation Safety Regulatory Cooperation (BASA) was developed by EASA to provide stakeholders with an up-to-date and easily readable publication. It was established by the combination of the corresponding text of the BASA, officially published, and all the amendments made to the BASA annexes adopted so far by the bilateral supervisory board. Please note, however, that this document is not an official publication. This document cannot have the same validity as an official text published in the Official Journal of the European Union, as it cannot be guaranteed that any recent changes to the legislation will be immediately included in the consolidated publication. Please understand, therefore, that the Agency cannot assume any liability arising from the risk associated with the use of this document. Readers are invited and encouraged to report errors or comments perceived at easa.europa.eu International in the context of this publication. A bilateral aviation security agreement (BASA) will be signed between the EU (and its member states) and a non-EU country. It is used when cooperation between the two parties is aimed at mutual recognition of certificates. EASA is helping the European Commission negotiate and implement these agreements. So far, the EU has concluded a BASA with the United States, Canada and Brazil. Working procedures are a type of agreement with a foreign CAA with which the FAA has not entered into a bilateral agreement. They are used to define methods by enabling the FAA aircraft certification service to assist another state in authorizing aeronautical products and items exported from the United States to that state. In accordance with the bilateral agreement BETWEEN the EU and the United States (BASA) (see below), a DUAL authorization is required for the acceptance of used engines/components of a US-based repair station.
EAS is working to facilitate the free movement of European products and services around the world. It helps non-European authorities certify European products and services. On the other hand, it issues European certificates for non-European products. Legal instruments for this purpose are bilateral agreements and labour agreements. In addition to airworthiness certification, basas, MoUs and WAs offer bilateral cooperation in other areas of aviation, including maintenance, air operations and environmental certification. Bilateral airworthiness agreements are executive agreements reached prior to 1996 through an exchange of diplomatic notes between the U.S. State Department and its foreign counterpart, based on the FAA`s technical recommendations. (Note: U.S. no longer enters into bilateral airworthiness agreements)) AMC M.A.501 (a)5(a)/AMC 145.A.42 (a)1a) refers to a publication document issued by an organisation as part of an existing bilateral agreement signed by the European Community. These agreements are being signed: bilateral agreements facilitate mutual airworthiness certification of imported/exported civil aviation products between two signatory states.
A bilateral airworthiness agreement (BAA) or a bilateral aviation security agreement (BASA) establishing airworthiness implementation procedures (IAP) provide for technical aviation cooperation between the FAA and its civil aviation authorities.
