This won't be what you want to hear, and you will need to find out for yourself - but from what I've read in the past the Tier II will cause issues with any current clearances. I remember reading a post about a guy that had to hire a lawyer to get his clearance back so he could fly his personal airplane a couple years ago.I was just notified that I’m tier 2 and will require further evaluation due to my MMPI results. I understand this will add some time to my FAA pre-employment which is fine but my worry is how this could affect me maintaining my class II for my current contract tower job. If anyone has any info on this, it would be greatly appreciated.
