And since our pilot records have been "improved" thanks to Congress, most of these options stick with you for life now, I believe.
Correct. An act of Congress last year put an end to the practice of expunging violations from pilot records five years after the violation. Administrative actions like Warning Notices, Letters of Correction, and remedial training still get expunged after two years.
BTW, while those things all get expunged from your "official" record, there is a dark vault deep in the ground below the FAA records center where
everything goes and
nothing gets expunged --
ever. It takes a very special situation (such as a Wright Brothers Award review) to get a "blue ribbon" package out of that hole, but if push ever comes to legal shove (say, you answered "no" on a question about whether you
ever had a violation because your last one was more than five years ago and was expunged under the old policy and a
criminal case is begun), that information could be used against you. However, one place where expunged actions will
not be seen is in an FAA violation proceeding, so if it's been more than two years since that Warning Notice about something you did, and you did it again and got caught, the investigating Inspector should not see anything about that old infraction.
