I'm using my original NavData.db3 from waaay back - copied it across each update (although I don't generally bother copying it from the laptop to the desktop) - and there is no HUNT in the actype table. Not that this really matters, as the actype table isn't actually used by RB as far as I'm aware.
However, I do have a selection of Hunter records in the aircraft table of NavData.db3.
Have you searched for 43C2EE in MyLog, just to make sure that it isn't hiding? I've just done this and there is our friend. There isn't a record in NavData, so the MyLog record isn't populated.
I will now manually add 43C2EE using DataBase Explorer and when I do a MyLog Populate, it should fill in the blanks.
