2-Reg
Before we all start think about putting our PA-28's and Cessna 150's on the 2-Reg, look at the potential cost....
From either N-reg or G-reg, the aircraft will almost certainly need an export C of A. Now, if you have ever had the CAA anywhere near your aircraft recently, you will know this is not an enjoyable experience and could be expensive (what is this tiny switch? do you have an STC for it?? where is the Form 1???).
Unless you are resident in the CI, you will still need an EASA Part FCL licence.
The IOM allow FAA or EASA maintenance but then send a surveyor to issue the C of A every year - that's not cheap, I bet.
The CI based companies that offer N-reg trusts are the most expensive for this service so I doubt the CI trust, if that's how it will be run, won't be cheap.
