Such agreements are currently signed: In accordance with the terms of the bilateral agreement BETWEEN the EU and the United States (BASA) (see here), you can only import an engine with the status “rebuilt” in block 11 if it has been released by the original engine manufacturer on a form 8130-3 using blocks 13a to 13e. (left). In addition to airworthiness certification, BASAs, moUs and WAs provide for bilateral cooperation in other aviation sectors, including maintenance, flight operations and environmental certification. CMT monitors and manages cooperation to enable the development and implementation of standard regulatory and policy solutions for certification issues and to support greater harmonization. The CAA and Japan`s Civil Aviation Bureau have also agreed on a new working agreement that would come into force in the absence of an agreement. The following rules will enter into force in the event of a no-deal withdrawal from the European Union. Further arrangements will be reached when the UK remains a member of the EASA system after its withdrawal. This applies to the case where component maintenance includes the installation of a used (sub)-owned component that is only authorised on an EASA Form 1 with “single release” and therefore the construction group is not suitable for US-registered aircraft. . . .
