AMC M.A.501 (a) 5(a) /AMC 145.A.42 (a)1 bis) refers to a declassification document issued by an organization in accordance with the terms of an existing bilateral agreement signed by the European Community. Such agreements are currently being signed: a bilateral aviation safety agreement (BASA) is signed between the EU (and its Member States) and a third country. It shall be used where cooperation between the two parties is aimed at the mutual recognition of certificates. ETA assists the European Commission in negotiating and implementing such agreements.

So far, the EU has concluded a BASA with the US, Canada and Brazil. The consolidated version of the “US-EU Agreement on Cooperation in the Regulation of Civil Aviation Security” was developed by EASA to provide stakeholders with an up-to-date and easily readable publication. It was developed by combining the officially published BASA text and all amendments 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 all recent changes to the legislation will be immediately included in the consolidated publication.
