so your saying Havick that I will have to show my CASA IPC is valid to an examiner doing an USA A320 check ride with my FAA medical and ATP license? Rubbish
If the FAA is directing you to your 'instructor/training organisation' and that organisation says you need a current IPC, then.......you need a current IPC. I know of two organisations that 'require a current ME IPC'
So, it's probably best to have a current ME IPC.
havick has been on this thread for a particularly long period of time, I don't know the person, haven't ever communicated with him/her but in this case, I'd be taking their advice. Some of the early E3's are now LCA's. Some of them have spent time in the training departments, I think they know what they're talking about.
