when I did my CFI initial there was in excess of a 4 month wait to use an FAA examiner. I study aircraft accidents in depth and I have yet to hear of an examiner sited as the reason for an accident. I have heard about CFI's being held liable because they forgot to put in a logbook entry that running out of fuel or flying into a thunderstorm might get you killed. I have joked many times that if I was sitting in the last row last seat of a 747 and it went down a contributing factor would the cfi not making the proper decision. To get back to the thread dont worry youll get past this and do fine. I failed a type rating check rating type once and as of yet no one has held it against me.
Good Luck
