Bilateral arrangements in the form of Bilateral Aviation Safety Agreements (BASA), Working Arrangements (WA) or Memorandum of Understanding (MoU) are in place between the UK/ Civil Aviation authority (CAA) and other countries and their aviation regulators. These enable design approvals of one country to be used in the other by a process of Acceptance or Validation. The processes are specific to each BASA or WA and are detailed in Implementation Procedures.
Details of the bilateral arrangements that the UK/CAA has in place.
There are two processes for validation:
- When the CAA is the Validating Authority (VA) for designs certificated by a Foreign Certification Authority (CA) seeking validation in the UK.
- When the CAA is the Certificating Authority (CA) and assists a UK Applicant in obtaining validation by a Foreign Validating Authority (VA) - also referred to as Certification Support for Validation (CSV).
Validations typically fall into one of three main categories, but the details within the Implementation Procedures specific to each bilateral arrangement must be checked before submitting an application:
| Acceptance |
For simpler design approvals such as minor changes/repairs and equipment approvals the VA accepts the approval issued by the CA without any further technical or administrative involvement. An application is not required and no validating approval certificate is issued. |
| Streamlined Validation |
Typically for simpler Type Certificates (TC)/Supplemental Type Certificates (STC) and major changes. An application is required and a validation certificate is issued without the need for a technical investigation. |
| Technical Validation |
For complex TCs and STCs and major changes. The VA may conduct a technical investigation but is generally limited to the areas of novel technology, safety significance or where there are significant differences between the certification standards of the CA and VA. An application is required and a validation certificate is issued. |
| Administrative Validation |
This simplified process requires no technical investigation by the CAA and is used in two cases:

Eligibility
Holders of a foreign Design Approval may apply to CAA for validation of their designs in the UK. That application should be made via their Certificating Authority (CA).
UK Design Approval Holders may apply via the CAA for validation of their designs by a foreign Validating Authority (VA)
For projects that are subject to Technical Validation, applications are also acceptable where a concurrent certification and validation is requested.
How do I apply?
An application for Streamlined or Technical Validation is made using CAA Form SRG1726NR.
An application for Administrative Validation is made using CAA Form SRG1727.
The process outlined here is generic and details may vary according to the Implementation Procedures associated with the respective BASA or Working Arrangement.
