Ambi: whist you state truth with regard to EASA (or whatever it morphs into), you should remember that the CAA are very adept at filing Exceptions to Euro rules.
And they could do so for this matter.
They already only partially recognise JAR OPS-3, even though all UK AOC Holders are forced to operate under these rules. The CAA does not recognise all of JAR OPS-3 - only the bits they like.
