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?
Variety of possible solutions:
- agree a comprehensive airworthiness bilateral with EU
- transition period of continued, temporary EASA membership or association
- agree stand-still arrangements with EASA
- etc.
Anyway I don't see how this is a problem:
- Non-UK reg'd a/c can be maintained in remaining EASA states
- UK reg's aircraft could have new UK Cs of A issued on back on EASA ones & UK AMOs can thus do work
