How could the CAA force you to have your N reg serviced in the USA? They MAY be able to stop you having it serviced in the UK (I don't know for sure, but suspect they could), but how could they stop you having it serviced in another country?
If you F reg has to be serviced in accordance with FAA regs to stay legal on the F reg, and it's not illegal under local laws to have it serviced in a particular country, then how could they stop you?
I mean could you not fly over to Ireland, and have it serviced here by an FAA approved outfit. CAA can't tell you what you can or can't do in Ireland on an F reg aircraft, flown on a FAA PPL.
Then when you are returning to the UK, you are flying in a N reg, with all its maitenance uptodate, and with an FAA licence. ie...you are ICAO compliant.
Am I missing something?
