212man - thanks, I did but my ATPLH was issued in 1991 and converted to EASA 2 years ago. My 139 TR was completed SP as I couldn't demonstrate completion of an MCC.
I may have got it all wrong and simply needed to show the ATO (non-UK) my logbook.
well if you have an EASA ATPL the CAA has already acknowledged you meet the MCC requirement as you cannot have one without. So the ATO doesn’t understand the rules! You may recall that some previous ATPL holders that only had SP types were only issued with EASA CPLs.
