The CAA does refer to the 2 year derogation in
this new document, e.g. page 10.
In this doc, they have correctly stated the EASA position re the
operator being non EU resident, and they explicitly state that the N-reg situation is OK till April 2014.
What is not clear (that I can see) is whether the present ICAO IR to JAA IR
15-hour conversion option will also continue till April 2014, or will end April 2012 as it currently appears.
