Turkish Airlines medical

[che ci dò che ci dò!]

Dear all,

I've just passed the screening for an A320 DEC position with THY but
I was stopped by their aeromedical centre just before the medical examination. The reason has been the OML limitation on my JAA class 1 certificate which was raised by my CAA's Ams following a cancer now in remission.
I understand THY medical examination consists of a full national initial class 1 and they couldn't let me go through it because an initial certificate cannot be issued with an OML limitation on it.
I was told that my position could be reconsidered in 6/12 months when the OML limitation will be lifted by my licencing authority.
I've just checked on the JAA website and I noticed that Turkey is Jar Fcl 3 compliant. If they're Jar compliant and I hold a valid Jar class 1 certificate, why the f__k I'd have to go through a full Turkish initial class 1 and they cannot just accept my JAA certificate?
Even the management pilot who checked my documents at the interview did say there would have been no problem. This issue was raised by the aeromedical centre thereafter.
Does any of you have any clue on how I could get away with it?

Thanks!
