How will these be renewed, if for instance a UK maintenance organisation is no longer allowed to sign out work on non-UK EASA aircraft?
So if a UK maintenance organisation continued to work to EASA standards and got another organisation (possibly even EASA itself) to certify that it was working to those standards, would that not solve the problem.
If IRC in my industry we worked to ISO9002 and there were a number of independent organisations that could certify us for that.
Surely it's the regulations you are working to and proving that that is what you are doing, that is the issue, not where you are doing it? Correct me if I am wrong on this.
